Adding heat/cool to rear Laramie seats

[brental1]

@brental1 .... I finally got the 2 connectors posted above, the harness isn't going to take long to make but finding the time is--- will update once complete--

-=F45=-

Did you have to buy a minimum quantity of the connectors? If so, do you have any to sell; and do you also have the pins?

 

[brental1]

I was wrong. I though you were asking about front; not rear.

Has anyone been able to make this work on 22 and up? I have all the parts to add venting; but I do not have the wire harnesses. Before I pursue harnessess, I want to make sure it's possible to add this option through computers.

I've made a lot of progress; but have one issue remaining. My truck, 2022 BH with Level 1 EQ, had none of the wires for the rear (also had none for the front) seats. I built a harness with XY430 and XY435A. 6 wires interconnect these 2 connectors. Also had to run 3 Fused Ignitions, 3 Grounds, and a pair for CAN IHS. New console harness (plus some additional wires including Fused Ignition and LIN BUS, I had to run from the truck to it). Added Rear seat heat/vent switches.. Then programming.. As of today, the Right Heat and Vent work.. Nothing on the Left works.. Seems I've narrowed it down to a bad Left switch. Strange because I both both switches new.

Open to any ideas on why the Left side doesn't work.

I'm wanting to do this myself.
I have a Laramie and have pulled the rears out for window replacement and have seen the harness is already there.
Thanks for all the Info Folks

I'd double check it all though, but this is what I have been able to find so far. Items labeled left/right, mean you have to buy 2.
As for body wire harness, I hope it's pre-wired as that bit is expensive.
Only 3 harnesses I found with label rear heat and they arr
68443995AC Body harness Heated Second Row Seats/Driver Seat Memory/6 Speakers/ParkView Rear Back-up Camera Parksense Ft/Rr Park Assist w Stop/Remote Start System
68444058AC Body harness 19 SPKR Harman Kardon Prem. Sound/ParkView Rear Back-up Camera/Blind Spot and Cross Path Detection/Parksense Ft/Rr Park Assist w Stop/Heated Second Row Seats/Driver Seat Memory
68444054AC Body harness 19 SPKR Harman Kardon Prem. Sound/Surround View Camera System/Heated Second Row Seats/Driver Seat Memory

In my opinion, up until body harness it is not that expensive to go factory. But as soon as body harness is added, it breaks the bank. And you'd have to tear the entire interior out, if you do have to swap in a different body harness. And the wiring goes under the truck and to engine compartment. Not worth it. So unless the rear heat module can be wired to the front, with a smaller harness it just won't be worth it. If I could get my hands on the ram wiring diagram, I could figure out what would be required to make a harness for that last run.
Or another option is to use all factory parts, minus the module. Then come up with a custom module(or 3rd party module) that can be wired to the factory switches and not require the need of the vehicle knowing it has rear heat/ventilation. Not like there is a menu on the touch screen for front to control it anyhow, so why the need for he body control unit to know it has it?

Thank You, Thank You, Thank You!!! I just made myself an Excel Spread sheet by copy pasting the parts into Mopar wholesale parts https://www.moparwholesaleparts.com/
Overall since my Laramie is wired not too bad as you said for a nice upgrade! You ROCK!
