** THIS IS A WORK IN PROGRESS. PLEASE BE PATIENT WHILE I RECREATE THE DELETED THREAD & ASSOCIATED LINKS AGAIN **
see ... 2013+ radio thread missing.

** Posts 1-12 and 15 are updated with working links and pictures **

I take NO credit for any of this, just wanted to sum this info up for everyone here. All credit goes to Getupkid, Duneflyer, Mondo161, Cptwing, PJW67, and others for getting this project started and all their research.

Be sure to thank Cptwing and Indaram for these original posts wherever you see them as well as the original folks who did all the work to figure this out...

(again, I had nothing to do with it, I'm merely the tech secretary here that put Humpty Dumpty back together again)

2018 & 19 CLASSIC OWNERS !]

* It is NOT recommended to install a 13-17 RAx radio in a 2018 or 19 classic!

It 'can' be done but you 'CURRENTLY' can't get rid of Cellular System needs service error message at startup (unless using the recommended 2018/19 classic UAx radio, & you will need ATC w/UAx upgrades to avoid hvac blend door issues).

Converting a 2013+ (thru 2016) RA1/RA2 MTC bezel
with 4 speed blower
to a RA3/RA4 MTC bezel and Radio.

** POST 17 : Important note/Caution about using cheap cloned blower resistors **


Cptwing said:
Cptwing's original post recreated/edited below...

It’s been quite a journey developing this harness along with Getupkid, Duneflyer, Mondo myself and several others. We now have a complete DIY solution for upgrading to the RA4 or RA3 from the RA1 and RA2 radios. The basic Radio is PNP now that we can use the 8.4 bezel and HVAC controls.

There are currently two factory setups for the hvac blower: the 7 speed and the 4 speed.

This is how I understand how the trucks were built, if they were equipped with the RA1 or RA2 radios.

2013 1500's have the 4 speed blower setup. (Fixed Displacement Compressor)
2013-2018 2500/3500's have the 4 speed blower set up. (Fixed Displacement Compressor)
2014-2018 1500's have the 7 speed blower set up (Var. Displacement Compressor)

NOTE:
The conversion for the 7 speed factory fan set up while similar is different and involves not only a different HVAC module but the pinouts for the conversion harness are also slightly different, see Post 2.


Parts Required For MOD:

01. 8.4 Uconnect Radio (VP3/RA3 - Non-Nav) or (VP4/RA4 - Nav)

** For Compatible RA4 Radios see here. **Check car-part.com, Schram, ebay, etc.

** Optional: DUAL ZONE 8.4" (ATC) BEZEL, while not preferred, will work. See POST 15

03. Base to 8.4 Radio Conversion Harness (4 speed Fan specific):
. . See below to make your own in standard or extended length
. . (or get an extended one from: M² Mods )

04. HVAC CONTROL MODULE: 68105017Ax (AA, AB, etc) (4 to 7 speed Fan specific). Replaces 68186216Ax, 68236773Ax, 68268187Ax.
. . ** If you use the wrong/incompatible module (ie xxxx8186Ax = No A/C & 6 vs 7 fan speeds)

< 10/4/19 edit > 2018 2500/3500's w/UAx = 68366553Ax HVAC module. See post 89.
** UAx Radio Upgrade has very high likelyhood of HVAC Blend door issues that are fixed by adding the ATC wiring mod with conversion. See links in UAQ/UAS Upgrade thread. **

05. Fan Motor Power/Resistor Harness: 68048906AA (Req's Modification)
. . (or see DeereGuy's write-up of 00R/T's notes to make your own at roll-up posts 1765-1766 or get the plug-n-play version at M² Mods ... watch out for poorly made ones elsewhere)

06. 7spd Blower Resistor: 68048901AA (same as Denso PN 499300-2121) See ebay ad and Post 51 )

07. 911 Error Fix/Cell Bypass Plug: (or SharkFin Antenna mod)

Next, the item 05. harness (purchased Fan Power/Resistor Harness) will need to be stripped down to retain only the needed parts. Here it is before mods...

dscn0471 - 68048906AA - Before - Fan Motor Power Resistor Harness.jpg
(updated picture, thanks JRG18) of the Fan Power Harness (as purchased) with added notes.
35579618172_3b31ebf798_c.jpg

In order to prep the bought harness (item 05), we must de-pin connector i32A (mis-ID'd as 132A), to do this you need to remove (release position) the TPA (terminal position assurance) the red thing. Then using a small jewelers screw driver pry back the locking tab and pull out the wire and pin.

Here is the connector and TPA (From later pictures).
34907649734_ee97d6e68a_c.jpg



Here is the stripped down unpinned harness item 05, this is what you will use the rest will be discarded.
dscn0471 - 68048906AA - MODDED Fan Motor Power Resistor Harness.jpg
35708560756_8022b0c2e7_k.jpg

The stripped down Fan Power harness (item 05) connects to the fabbed Conversion Harness (item 03) on the HVAC module side using the DB/LB 16 gauge wire that goes to pin 2 in the resistor plug. I cut this wire to 25.0 inches long and crimped a female pin on it for the 24 pin connector and inserted it into cavity number 17. Note this is a 16 gauge wire and these pins are not designed for wire this thick so you will only be able to crimp the stranded wire into the pin and not the insulation. The other alternative would be to crimp a pin on a smaller 22awg or 24awg wire and solder them together (or butt splice=less reliable).

MPG edit: I think a 12" (i.e. 22Awg) pinned extension for pin 17 would allow better routing of the wire.
Also recommend not shortening the wires.

Next I cut the black ground wire coming out of the resistor plug to 20.0 inches long and crimped a 10 gauge ring connector onto the end and shrunk wrapped the connection.

The DB wire coming out of cavity 3 of the resistor plug is not to be cut. This wire is to be used to re-pin the existing i32A (prev. mis-ID'd as 132A) connector on your truck. I looped the excess wire back and taped it off.

. . (or see DeereGuy's write-up of 00R/T's notes to make your own at roll-up posts 1765-1766 {edit: lost with prior thread delete} or get one ready to go at M² Mods)

Now for the install,

First disconnect the battery, remove the following; center stack (and radio for access), cardboard bottom located under lower glove box, lower glove box and upper glove box cavity (door does not need to be removed), passengers side kick panel and passengers side dashboard end trim piece.

Note: Removing/Installing the radio and bezel are not covered here as there are several places on YouTube/internet that cover it (Separate instruction sheet available in post 3).

Mpgrimm2's panel/prep notes:

Radio C1 Connector Latch
35361938310_b5fc205380_b.jpg

Once the center stack and RA1/RA2 are removed, you will need to swap out the old bezel/HVAC controls for the RA3/RA4 (8.4A/AN) bezel. Set this aside until later.

Now for the parts install...

To install module slide it in through the lower glovebox cavity and position the two hex head screw into the keyhole cut outs in the dashboard sub structure and slide forward and tighten see below.

Make sure to orient with plug farthest forward to clear lower glove box when operating, see 3rd photo on this post.

Resistor & HVAC Modules factory locations.jpg
34940140733_8367bd59e2.jpg

Now to install the harness we have to first replace the existing resistor with the new one (part 3), remove the 2 phillips head screws securing the existing one and replace it with the new one using the existing screws.


Here is the existing resistor prior to removal

Now to install the harness:
Unplug the existing connector from the motor and tape it off along with the existing resistor plug they will not be used. Then unplug connector i32A (prev. mis-ID'd as 132A) and replace the wire located in cavity 7 with the one in the new harness, this is the 10 gauge wire you unpinned from part 1.

Plug harness into module and begin routing it to radio bezel along the same route as the existing body harness and SDAR / Cell antenna leads. The new harness is shown wrapped in corrugated split loom.

Finish routing the harness into the center stack area and plug the 24 pin connector on the harness into the existing 24 pin connector on the truck. Plug in the connectors you previously unplugged and also plug in the 8 pin plug into you new bezel.

Harness coming in behind bezel:

Reconnect battery and test everything and ensure it is working correctly. Reassemble your truck

And here is the bezel installed while testing harness showing all 7 fan speeds, yes that's right the fan now has seven speeds it seems to push more air and is quieter.

34940862973_48e81778ea.jpg

And here is the finished job! Everything on the bezel works as it should. Works perfectly!

Oh and prior to bundling it up I tried two other bezels I had. Both are dual zone with auto climate control. They also worked except for the actual dual zone or auto climate control functions. The drivers side temp switches were active to control the temp, but the passengers side temp buttons did nothing. Otherwise they were fully functional. Just something to think about if you already have an auto climate control bezel and do not want to buy another one. SEE HERE.
Enjoy

Cptwing's notes for making the conversion harness

Cptwing said:

First let me say I am no wiring GURU either! But I want to play one on TV.

The numbers are embossed on the connector shells, they are very small and depending on your age and eyesight you may need to use magnification to see them. Not all the cavaties are numbered just the outside 4 on any given connector, but they run sequential. The 8 pin connector is top row 1 thru 4 and bottom row 5 thru 8. For the 24 pin connector shells the top row is 1 thru 12 and the bottom row is 13 thru 24.

If your vision is normal, I would still recommend a nice pair or magnifying glasses to make thing easier on yourself, these connectors and pins are very small and the extra seeing power will come in handy.
,
As you say it is easy enough, the big key is having the correct crimping tool. The cheap crimping tool that come in the Walmart and Benny's kits will not work. The crimps need to be formed into a double roll, if you just squish them like the cheap crimp tools do they will not fit into the connector shell cavities.

I highly recommend a ratchet type crimper, these are the crimpers I used, they work perfectly, have great reviews and are not that expensive.
http://www.amazon.com/Iwiss-Crimping...molex+crimpers

crimpers.jpg

First remove approx. 1/8 inch of insulation from the wire
Second click the crimper until it just holds the pin in the jaws
Third slide the wire into the terminal pin until it seats and the insulation is inside the pin...
...Note these pins have two separate crimping sections which crimp simultaneously one the inner one is for the
...actual lead and the outer one is for the insulation.
Fourth squeeze the crimping pliers completely in one steady even motion.

The dies in the jaws of these crimpers are for different wire gauges, in addition each of those is a two section die, one is for the crimp with the just the wire and the other is for the crimp with the wire and insulation. In other words they are meant to be used one way, always slide the pins in from the side. The pins are inserted in the jaws from the side shown in the above picture.

Buy extra pins and do a few practice ones. The pins are very cheap, but the shipping is no, having to place an order for more pins would suck.

You could use quick splices, I assume you mean the 3M quick taps I would rather solder and heat shrink them for a more reliable connection, the 3M quick taps are also bulky as you would need to use 5 of them.

Ok I finally figured how to take macro pictures with my camera. So I thought I would share some information and examples of crimping pins and how to identify the cavity numbers on a connector.

Here is a picture of the 8 pin plug that plugs into the radio\hvac bezel alongside it is a 20 gauge wire crimped into a pin, note this pin is not for this connector (it is actually for the 3rd brake light connector) , but this gives you an idea of the size.
dscn0818.jpg


Next we have a close up shot of that pin alongside another pin crimped to 18 gauge wire that is used for the overhead map lamps, notice how the crimps are formed into a double roll and the insulation is crimped separate from the stranded wire. One of these is a factory crimp and one I did using the crimpers in the above post. I did the black one, which in my opinion is actually a better crimp notice the roll on the insulation of the two.
dscn0822.jpg

Next is an isometric shot of the 8 pin plug, the red piece is called the TPA (Terminal Position Assurance) or secondary lock. It actually has 10 slots, the outside 4 slots are used to access the locking tabs if you need to remove it. as pictured the TPA is in the unlock position, after all the wires are inserted into the various cavities it is pushed it and locks in place. Note not all connector shells use these, the 24 pin connector shells used to make the rest of the 8.4 conversion harness do not have them.
dscn0826.jpg

Next we are looking down on the connector TPA side which is the end that plugs into the bezel. Notice the numbers 1 and 4 on the top row and 5 and 8 on the bottom row.
dscn0824.jpg

Next we are looking up at the connector cavity side which is the end that the wires are inserted into. Notice the numbers 1 and 4 on the top row and 5 and 8 on the bottom row.

The RA3 and RA4 radios contain a sierra wireless aircard (cellphone), used to talk to 911 and useless connect. Since your current radio RA1 or RA2 does not have that capability your current antenna does not have the cellular antenna in it.

The one you currently have is called a puck and has one plug used for GPS and XM. The sharkfin has 2 plugs the other being for cellular.
33265613328_7622fa07a6_z.jpg

Without the extra cellular antenna the RA3 and RA4 radios will flash an error stating that the vehicle phone needs to be serviced.
46417337664_451eeece67_o.jpg[/url]

Replacing the antenna and leads is more expensive and difficult, so most opt for the dummy antenna seen in the Original Post. Many on here have made their own dummy antennas.
40176117793_8b4e0ab525_z.jpg

The benefit I have gotten out of adding the sharkfin is:

With my 2014 radio
911 works
Yelp works

With my 2015 radio
911 works
Yelp works
Roadside assistance thru Ram works
Registration screen comes up and phone dials and connects but I hung up not knowing what they could do to screw up my radio.

Not just by size but by type as well. The 52 position radio connector on the 2013 and up actually uses 2 different pin types. To find the correct pins you need the manufacture's part data drawing. In addition the connector drawings will list multiple size pins for the connector by wire size, so to match those up you need the pinout diagram from the techauthority website. The two types of pins used are 2.8mm and .64mm, while these pins are available for different wire size gauges, I have listed only the ones used by Fiat on the 2013+ trucks

Here is the Radio connector

For some reason the drawing no longer lists the pin part numbers for the 52 position connector, so here they are.

Here is the data sheet for the radio connector

FYI for the other 4 speed fan conversion folks...

Mondo posted this (here or the z) a while back and is a good reference for those of us that have to use the extra Blower Power Harness with the conversion harness.

@cptwing, can you add this to your post 85 link?

A couple notes on possible crimp tools for those wanting to make their own harness. If anyone else has links/details to affordable ones they used that worked well please let me know and I will update this post...

The link to the crimper cptwing used is/was broken.
It may have been this one by iWiss <--- RECOMMENDED!


From the original backup Cam thread..


The official Amp/TE Connectivity "Pro Crimper III" tool is likely upwards of around $210 at Newark or Mouser.
Manufacturer: TE CONNECTIVITY / AMP
Newark Part No.: 44F8409 (LINK)
Manufacturer Part No 58495-1

Note: A bread bag's Twist Tie with about 3/8" of the coating stripped off, makes a fairly decent pin lock/release tool if you need to pop out pins from the connectors after they have been installed....

I need to build a harness where did everyone get the connector ends and pins or I did not see them in the post thx in advance

Mouser Electronics, DigiKey Electronics, Newark Electronics, Allied Electronics, Nexus Electronics (NexElec.com) depending on who you can locate in-stock qty and reasonable minimums.

MPgrimm2 Harness Notes:

For those of you making your own extended harness, here is a bit of details from mine that may help you...

- Use twisted & soldered connections for splices (blobs can be unreliable)
- Use 1/8” heatshrink over splices vs electrical tape
- (optional) Lightly ‘flow’ solder at all pin crimps for durability and to prevent “pullouts”.

- Some other useful accessories if you do a lot of this stuff:
I use a Weller WES51 soldering iron with ET0 tip, helping hands, Solder Tip Cleaner, Kester 60/40 Solder (or similar),

- Here's a kit of wire with (6) 25ft rolls of 22awg wire with 6 different colors
or (10) 25ft rolls of 22awg wire with 10 different colors (10 Colors to match the schematic)

- Here's Braided sleeving: 25 FT 3/8" Black Expandable Wire Cable Sleeving Sheathing Braided Loom Tubing (main harness)
and 5 FT 1/4" Black Expandable Wire Cable Sleeving Sheathing Braided Loom Tubing (bezel segment)

00R/T's Crimping Notes:

00R/T said:

It's hard to explain how I crimp it, but I'll try.

Strip the wire so the exposed wire is just slightly longer than the wire crimp portion of the terminal.

Set the wire in the terminal so the insulation butts up against the wire crimp portion of the terminal.

Use pliers to press the insulation portion of the terminal (the ears) into the insulation just enough so the terminal will stay in position.

Hold the crimper so the open "mouth" end is facing you.

Place the terminal in the crimper with the open part of the terminal (the fins that fold over) facing the bottom of the crimper.

Align the terminal left-to-right so the insulation side is on the wider part of the crimping die and the wire side is on the narrower side.

Slowly close the crimper and make sure the terminal doesn't rotate.

Close the crimper all the way.

Fix the insulation part of the crimp with pliers if it isn't as round as it should be.

EDIT: On your crimper, the open side of the terminal may go up. You want it facing the part of the die that has the line down the center (like the top of a heart).

More Mpgrimm2 Extended Harness "Braided Sleeving" notes:

NOTE: I used braided nylon sleeving and heatshrink which can be a bit more difficult to work with vs split wire loom.

(i.e. I covered harness with 1/2' nylon sleeve/braiding. Finished with 3/4" & 1/2" heatshrink.)

Just a quick note on the bezel ...

There are 2 bezels that will work with the 8.4AN conversion...

- Preferred option 1:
SINGLE ZONE OEM 8.4" (MTC) BEZEL
P/N: 1UJ96DX9AC or 5VD75JXPAA (or AE, AF, etc)

40176284813_c2abcedca2_z.jpg

- Workable option 2:
DUAL ZONE OEM 8.4" (ATC) BEZEL
P/N: 1UJ97DX9AC or 5VD73JXPAC (or AE, AF, etc)

Cptwing said:

Yes the dual auto climate bezels will work, but will function as single zone manual climate control. The ATC bezel has all the same controls/buttons but also has 3 extra buttons that will be non-functional with the basic 8.4 upgrade/HVAC conversion; ie the 2 right side buttons (up/dwn) for the passenger side Temp control (dual zone), and 1 (1/2) button on the center knob for the Auto temperature feature.

Only the driver’s side temp button will function and the auto function will not work. But besides that it will function the same way.


The ATC bezel was verified to work minus the items noted above by Cptwing, Jared4.7, See Here, (and later by Mpgrimm2).

Jan 11, 2016

EDIT:
You can now enable/add Single Zone ATC (still no dual zone!)
- How to Add (ATC) to a Manual Temperature Control Truck

& it's possible to combine both bezels for a Single Zone ATC Bezel, see post 8 of ATC Thread.

EDIT 2:
If you really want to pursue true dual Zone ATC, it's possible but very involved.

While it's not recommended to install a 13-17 RAx radio in a 2018 or 19 classic it can be done with the correct parts but you 'CURRENTLY' can't get rid of Cellular System needs service error message at startup (unless using a 2018 UAx radio).

A heads up about using cheap Chinese clone blower motor/fan resistors....

IMO... You're better off getting a used OEM one vs a new clones version.

.just troubleshoot a similar situation and it turned out that a genuine resistor fixed the issue. Here's video of the issue with clone resistor vs OEM resistor

Updated video Link: https://youtu.be/STwZpe4pns4

Vs.

OEM resistor...Updated Video Link: https://youtu.be/2cfE0LAM_Ps


Thanks for posting. The fact that you bought a kit and can't get people to respond back when you have an issue after several days and had to contact me, is well ...


Let's see a picture of the resistor itself ie the face of it... I can tell if it's one of the Chinese clones vs Mopar/denso. I've seen reports from people claiming these work fine and I bet the clone is what you've got.

You don't even have to take it out. Here's a picture of a $100 genuine resistor vs $20 clone. (I've also see a clone resistor that looks nearly identical, and has issues. Probably used the original molds)

Spare post 20. - That should be enough posts for now if anyone wants to comment/add relevant info. ** I will go back and edit the first 15 posts when I get the chance **

Alright. 3.5hrs digging through cached webpages and I'm burnt out.

- Managed to get most of the Cptwing's Info on the conversion for 4 speed fan folks
(But no pictures)

- Absolutely could not locate a cached page of Indaram's Original post for the 7 Speed fan folks.

That original thread is locked and the relevant posts are missing.


- The 4 speed fan instructions by Cptwing at posts 81, 85, 88, 89, & 90 are lost along with the detailed pictures he posted.
I managed to dig them out from Google's cached web pages archive, but without the pictures.

-Indaram's original post 1 from his consolidated info thread detailing the 7 speed conversion was lost (part numbers, links, etc) and the entirety of his thread are gone.
I was able to go through the cached Google pages for relevant posts, but couldn't locate a cached page for Indaram's post 1.
