I too had already purchased this same module "68217268AF" before reading this. I hooked it up yesterday to my 2013 Laramie Mega/Cummins. I'm attempting to enable my soft keys for heated/vent/ seats/steering after upgrading from my Harmon to a UAS head unit. It seems that I will also need to retrofit a harness as mine is missing 2 of the 6 connector plugs for the newer module (68217268AF). Can anybody help with a harness P#?

You can get in touch with Mike of M2Mods on this forum. Get him some information and pictures and he can probably figure out what's needed.


Remember, if all else fails you can buy the module from Customtronix to correct the soft key issue even though it's kinda pricey. I think I paid around $250 for mine but it did work for the soft keys. It didn't help with any of the other known issues though.

Bring a few posts from another thread over here for reference....

I did a writeup on this this year's ago when with the help of 00/RT I was the first person to install the heated/vented seats in an Express/Tradesman. This has become an extremely popular upgrade that had been done by several people. I'm not sure where you got some of your information but there is already a thread dedicated to this. I will answer your questions with facts. I have done this to several trucks.

All 4th gen 13 to 18 come with the column pre wired for the heated steering wheel and adjustable pedals. I would think the Classic is the same but I haven't done a Classic yet. They do this because they install the same column in all the trucks no matter what the trim level is. There will be a connector that is in a dummy slot that's located in the clockspring. This is for the heated wheel Clockspring if equipped.

If your truck has two pink wires with yellow stripes going to the drivers seat yellow seat connector (i400) your truck is pre wired. If it doesn't have those two wires it's not. It's that simple.

The heated steering wheel will NOT work without the heated seat. It is controlled by the HSM (Heated Seat Module)

The dealer cannot enable these codes for you if you have an Express/Tradesman because they are not offered/allowed in your trim level. You will need the Alfa tool to enable them.

Regular Cabs are pre wired for the heated/vented seats and heated wheel because they build so few they use the same harness in all the R/C trucks.

Express/Tradesman Quad Cabs and Crew Cabs are normally not pre wired but I have heard some say that some of the Classic trucks have more of the wiring so you may get lucky. I haven't personally seen this.

If you have the wiring you will only need the heated/vented seats, heated wheel, heated wheel clockspring, switch panel and then enable the correct codes.

If your truck is not pre wired you will need all those things plus a conversion harness from M2 Mods (Mpgrimm2) who you can contact in the vendor section of the forum.

You don't need to add the heated wheel in order for the heated/vented seats to work. It can be added later if you chose.

In some cases the vented seats don't play well with the 3" or 5" screen radios. More so with the 3". In most cases people need to upgrade to the 8.4" radio but I have seen a few work with the 5".

HSM is part of the upgraded seat Set (driver side), ie Bighorn heated seats or higher trim. Laramie & higher seats have heated/vented leather (some Sport seats have both, but not all).

Make sure to get 2013-18/classic 4th Gen seats with SRS Airbag tags. 09-12 will bolt up but are wired differently/not compatible and don't have airbags. 2019+ 2500/3500's are 5th gen trucks and are also electrically different but will bolt up & should not be used.

There was a slight wiring change to floor length consoles in 2017+ that can affect heated rear seats and panel illumination for the usb hub... Otherwise the same.

Mike(M2 Mods) is a member of the forum and builds harnesses for the 8.4 radio conversion, heated vented seats and heated wheel ect. He is one of the guys who helped develop a lot of the harnesses we use. We speak often about ideas and possible harnesses. He is very knowledgeable and builds harnesses that look factory. I have installed several of his harnesses in trucks with no issues. The harness has nothing to do with any of the other features of the seats such as seat belt chimes, occupancy sensors ect. The harness simply plugs into the connector in the pins that aren't occupied. It is strait forward and well labeled. He also has detailed instructions. It is not hard to install at all if you familiarize yourself with the harness before you start.

All Laramie's have memory. If you get Laramie seats he can include the memory wiring as well. The passenger side seat will have the power inverter mounted to the seat bottom. You can also make this feature work and install the factory 115v outlet in your dash if you chose. Only the Laramie has memory seats and only the Laramie are heated and vented standard.

The Sport looks pretty much the same but they aren't available in memory and the vented feature is an option and not standard.

The Bighorn is only available heated if optioned & has no memory and most are power adjust on the driver's side only. If you get Bighorn seats make sure they're actually heated. They are listed incorrectly all the time.
If you install the Laramie seats you can also install memory mirrors and memory adjustable pedals. Plus the truck will have the radio settings and climate control memory. I have all these features working on my 14 Express.

It is critical that you get seats from a 13 or newer 4th gen, preferably a newer version as there have been people report issues with the earlier HSM (Heated Seat Module) having glitches in the later trucks. The wiring is identical so you could install a newer version of the HSM if you got earlier seats and had issues with the HSM.

Correct me if I'm wrong since you & STecoD have actually put hands on more of these then just about anyone ...

He doesn't have the wiring to support heated/cooled seats?

- I don't see the matching grey, i401 (20 pin) plug for heated cooled seats coming out of the floor on the driver side (just the yellow i400 and grey i410).

- I don't see the ground wire at i420 pin 21 (yel) passenger side plug.

It would appear he does Not.

I always just tell everyone to look for the two pink wires with yellow stripes in the driver's seat yellow connector.

If you have that wiring then you at least have the wiring for the heated/vented seats and heated wheel. I tell people to just look for those two wires because it's quick and easy to check and in some cases I have seen the trucks had the 20 pin connector but it was shoved under the carpet for some reason and guys didn't think they had it. You will most likely not have the 4 extra wires for memory seats and mirrors or the 7 extra wires for memory pedals if you want them even if your truck came with the heated/vented seats and heated wheel wiring but obviouslyyou can add that wiring if wanted.

This is a pic of the MINIMUM wiring needed for Non Memory Heated/Vented Seats and Heated Wheel. You can see the two pink wires with yellow stripe in the yellow seat connector if it has that it will also have the 20 pin gray connector that's shown in this picture but it's sometimes under the carpet.

Other issues. The module did fix the heated/vented seats and heated wheel soft key issues.

I will be replacing my front driver manual seat with a powered seat (no heat, no cooling, no memory). The connector under the seat on my SLT apparently does NOT have the 12v power that is needed. What is the recommended gauge wire if I want to run the power from the battery to the connector under the seat? Do I also need to run ground wire? Any ideas on good location/method for getting through the firewall?

Thanks

It should work without a separate ground wire in most cases because the seat is grounded to the floor of the truck. Make sure you run an in line fuse for the power wire. I usually use a 20 Amp fuse. Run it through the clutch pedal delete plate as Mpgrimm2 stated.

Thank you... Before I start pulling new wires and tearing out the old seat - I am comparing the connectors under the powered seat with the connectors under the original seat. I notice that the powered seat has an extra gray plug with one black wire, that my original seat does not have. What is this one wire, gray plug for? Can I just ignore it?

EDIT: Install complete, working great even with nothing connecting anything to the extra gray plug.

The grey 20 pin connector is for heated/vented seats and memory pedals. it's not necessary in your application

Hey Fellas,

I have a 2014 SLT 5.7 Hemi 1500.

I'm going to be installing AFTERMARKET heated seats (I had them installed when I did leather upholstery). So, my question is:

1. What would I need to do in order to bring power to them? Is there power underneath the seats already that I could use? These are manually-operated seats.

I am also going to be replacing the steering wheel.

1. It's to upgrade to the audio controls (doing the cluster, too).
2. It just so happens it is heated.
3. I have the clockspring for the heated steering wheel.
4. I have the 5.0 touchscreen and do not intend on programming it (if that's even possible); but,
5. I DO intend on replacing my hard switches below the HVAC panel. At present I think I have the traction control shutoff and one other button...the rest are blanks.

Again, not factory for the heated seats, and only a hard switch to activate the heated steering wheel. By the way, COULD I use the hard buttons on the dash for the seats as well? If not, it has the switches that are drilled into the side of the seat.

Any help with parts and process would be greatly appreciated!

Best,

Maitai

Not working:
Heated Steering Wheel shows in radio under controls. When pressed, turns on for ~5sec then turns off.

Heated/vented seat icons MIA in radio.
-have double-checked Alfa
-have cycled radio
-have given radio days to take changes
-have pulled fuse to hard reset radio

I wasn't able to find the HSM initialize command in Alfa and am wondering if that might help the HSM and radio communicate.

I can connect to both MSM and HSM through alfaobd.

In the MSM I have a code B1D98. I ran a system check and the seat moved, but test stated failed.

In the HSM I had a code U1446. I was able to function the vents on high and low correctly as well as heat, but the test ends before you can really feel any heat in the seat.

I am NOT using the hard button panel, due to having the 5 aux buttons populating the bottom row. Unfortunately can not check functionality there.

My new heated steering wheel came with 2 connectors, one white, one black. The white one connects to the clockspring, the small, 2pin, black connector doesn't have a home. I'm using the wheel harness that came with my express steering wheel, do I need to purchase/install a specific heated wheel harness?
