Looking for heated seats and steering wheel wiring

[BlueRam]

Hi everyone,

I have a Dodge Journey 2012 facelift (SXT), 3.6L, FWD.
From the factory, the vehicle was not equipped with heated seats and a heated steering wheel.

I sourced the seats and steering wheel from a salvage yard, but it turns out that’s not enough.

The connector where the seat plugs in goes down into the floor, and in my car those connectors have significantly fewer wires.

I was able to trace the additional wires up to the firewall; they go behind the HVAC unit, but I couldn’t trace them any further.

 

Does anyone have photos, wiring diagrams, or schematics showing this wiring—specifically where these additional wires go and how they are routed?

I would be extremely grateful for any help, as winter has arrived and I’d really prefer not to freeze in the car every morning 🙂

Thank you in advance!

You will need more than wiring there's  modules and the BCM would need to be set up

Also the Uconnect might need to be upgraded as it involves the touch screen...good luck

Thanks for answer.
I already have updated uconnect and I guess I have all modules I need.

Clock spring  in steering column for air bags\horn are different in heated steering wheel optioned cars. Keep it in mind if heated steering doesn't work when enabled by alpha obd programmer. May have to add a wire or get heated steering wheel vehicle clock spring to install from wrecker.

 

Our 2014 journey has the heated steering wheel, only turns on in the 8.4" main screen. Very nice in the winter.

Do you have the heated seats module, secured to the underside of the drivers seat?

[John/Horace]

He hasn't mentioned driver powered seat function. Probably a mouth full of turkey right now. If it's power to power seat swap, that harness may already have the heated seat wires in it. Would make it simpler.

 

Active head restraints are on some US models, but I believe not north of border models. One less thing to worry about I guess.

Of course the seat has that module. The question is not about the module or anything else. I’m asking specifically about the wiring that goes from the connector in the floor under the carpet.

Thanks. If I had the required wires, I wouldn’t have created this thread.

The wires are not there — that’s exactly why this topic exists. And my question is not about headrests, not about the module, and not about power seats. The presence of a power seat does not 100% mean the presence of heated seats.

Thanks everybody for the “help”.

I’ve already found all the wiring diagrams in the service manual, which was kindly posted in another forum thread.

Wire them up....
