I have a 2019 Classic Tradesman with the 5.0 with backup cam in mirror and manual AC controls and no steering wheel controls. I want to do the 8.4 upgrade with Android Auto, Back up cam in the screen and auto climate controls. How much would all the harnesses be to purchase from you? I'm refusing to buy anything from Infotainment. Also, I guess a missed the part number list for all of this, if someone could help me out please and thanks.
I'll send you a message with details to get things started shortly.

Guess because my account is new, I can't reply. I have the Uconnect 3.0 with handsfree and camera in the mirror.
That's okay. Since you can read the message, go ahead and send me an email with the requested info and I will get you squared away.

Shout out to M2 mods. Ordered my harness last week got it in mail within a few days. Well worth the $ for the harness as i always wanted a 8.4 with nav on my 2013. All plug and play no splicing. Detailed instructions and very informative.

Very impressed with the quality of the harness and the customer service. My nav swap and a/c upgrade work perfectly and were worth every penny. I like that the harness already has the ATC plug included, this was the only harness I found that included it.

Thank you Mike from M2 Mods for helping me with all my questions!

I recently upgraded to a 8.4 and after reading the instructions in this thread, I contacted Mike for the harness I needed for the HVAC module. I am new to this whole thing and Mike answered all my questions and gave me all the information I needed to do the job. When I ran into a few snags with what was happening, Mike responded quickly with very helpful information.

in the end, the whole process was pretty smooth and with the easy to follow instructions it helped a novice like myself.

I definitely am looking to modify something else just so I can get another harness from Mike!!

Finally - the upgrade that started almost a year ago, is finished and working correctly! I have @Mpgrimm2 and M2 Mods to thank.

I didn't buy from him from the beginning, wish I had - but I've removed the previous vendors harness, and used his (which he shipped in about a day after placing the order!) The installation instructions were above industry standard, and he was willing to offer assistance over the phone, at the drop of a pin. The quality and workmanship of the cabling, top notch.

I now have the humidity sensor installed, my A/C compressor is running only when called for, and my ATC is working FLAWLESSLY.

I can't say enough good things - he clearly is an asset to this group and community, cleaning up mess left from the other "vendors" installations.

My only regret, not finding this thread before my initial purchase.

I have a complete 2017 RA4 VP4-NA Upgrade kit with SINGLE ZONE ATC hardware option and Includes custom Single Zone ATC bezel...

** This is not an Android Auto Apple Carplay radio**.
(extra sensor Included for 4 speed 2500/3500, ATC wiring is already built in to the harness. 1500 req's an extra harness and sensor for a bit more). Ideally for a 2013-17 ram but can be used in a 2018/classic truck, but will have cell error service message that can be fixed with a work around.

Comes with used/tested 17ra4 w/unlock code & sw v18.45.x (very good condition), custom Single Zone ATC bezel, cell bypass plug, new HVAC module, our universal conversion harness with ATC (& New Mopar/ Denso fan Resistor & Plug n play fan harness for 2500/3500's).... & I can swap out parts for 1500 ATC harness setup.

17ra4 Nav radio & custom Single Zone ATC kit for 2013 -17 4spd 2500/3500 trucks

- 17 RA4 VP4-NA nav radio 68260661Ax with unlock code and sw version 18.45.01

- Custom 8.4 Single Zone ATC Bezel (see here.)

- 4/7 spd Universal Conversion harness w/ATC Pt1 v4
- 4 to 7 Speed Fan MTR Power harness v4 (plug n play)
- Cell Error Bypass Plug
- Mopar/Denso Fan Resistor and HVAC module for 2500/3500’s with RAx radio - New
- ATC Cabin Temp Sensor - New


Message me if interested. SOLD shipped/USA.

(Can also split up the kit if you have your own radio, ie UAQ or UAS that requires Single Zone ATC to work correctly, or can offer a new Single Zone MTC Bezel without the ATC sensor for $150 less. You can still add ATC later).

Glad you got the programming handled and can enjoy it.
I can still get you setup with a custom 8.4 Single Zone ATC bezel to finish off your ATC upgrade if you like.

Huge shout out to Mpgrimm2! I had a handful of questions I'm sure he's answered a thousand times, but he answered them all, and got me squared away in no time. I ordered up an VP4 w/nav, his harness, a 4 to 7 speed fan resistor and module, and the cell bypass. 8.4.jpg

The harness is impressive, to say the least. Instructions are easy to follow, and took me just about 90 minutes to do, since it was my first one.

I'm happy that I was able to support a forum member. If you guys take a minute and look, he's been actively developing this swap since these trucks came out!

If you're even considering an aftermarket deck to replace the joke that is the RA2, don't waste your time, just message Grimm!

You won't be able to use uConnect app/features ... FCA/Stellantis won't allow any non factory 8.4 upgraded trucks on their network.

If you have the original VIN/truck & radio info maybe you can claim that you bought the truck or it was a salvage title to get it working with them.

I've only heard of 2 or 3 people claim to get it working, but have never seen any proof or explanation of how it was done exactly.

Hello,
I have a 2018 Ram 2500 with the 4 speed fan. Wanting to install the 8.4 radio I found Mike Grim. After many questions because I have OCD and have to understand what is going on I purchased a wire harness, 911 bypass, hvac module and resistor. Instructions were easy to follow with pictures! Everything worked just like it was supposed to. I now have 7 speeds on the AC! No error code for 911. And most important volume controls! Plug and play. Get what you pay for! Thanks Mike!

I'm starting to gather all of the items needed to upgrade my 2018 3500 Tradesman 5.0 radio to the UAQ NAV radio. I ordered a used bezel with the one zone HVAC but have a question in regards to volume control. Is there a harness to buy that allows the volume control button to work once you upgrade? I don't have the steering controls and that looks like a huge PITA to install. It looks like Infotainment has a harness to get it working but I know they are way overpriced. Thanks for the help.
