Heated Steering Wheel - It can be done.

[RainierJeep]

Okay... I was able to feed the wiring harness through the firewall on the driver's side. I ran all the wires to the correct locations and then installed the heated pads on the drivers side. Bolted everything back together and reconnected the batteries. The lights turned on and I went inside the jeep to turn it on and it went black. dome lights, interior, all of it. I thought the battery may have died so i connected a battery charger and I could hear a clicking in the fuse box. Any ideas what happened and what I did wrong!

While the batteries were disconnected did the cables touch any thing metal? Sounds like the z case fuse is blown.

went back out and disconnected the power tap and reconnected the batteries. Everything turned on and the jeep started up fine. My uconnect only had HI LO and would not adjust to different temps but the heat was working. Thinking thats just because it was sitting for a while.


Could it be a bad ground? i used the body ground in the drivers side footwell

The body ground in the footwell should be fine, I have several things grounded there. Where were you pulling the power from?​

If you disconnected both batteries the uconnect needs time to reset.

I ran it straight to the battery. I relocated the grounds for the ground on the driverside footwell and the relay under the hood to be sure. Everything is back to normal but no heated seat. Just used the jscan and turned the heated seats function on, but didn't work when i tried to turn them on in the the vehicle.. will try again tomorrow.

When I just enabled the wheel in mine I had to restart all ECU’s and let it sit for awhile before it showed up in the radio and worked.

Hello all,

install is done and the seats are working. A couple of quick points for those that want to use the infotainment wiring harness.

1. I back-fed the wiring through the driver side firewall plug. Manual owners would need to find an alternative way.

2. the 12 volt connector is so long bc you are supposed to use the cigar lighter in the cargo area and move the fuse to battery. I connected to the cigar lighter in the dash and the seats don’t turn on with the auto start.

3. the heat is not as hot as my factory gladiator was. That being said, my temp gun measured 104 after I drove around the jeep for 30 min. High is still very warm and I moved to med heat and was very comfortable on a 20 degree day. It does not get blister your skin hot through. Maybe better than factory?

I hope this helps and it was easy once I figured out where to route everything. I would purchase again if I needed to do this for another vehicle

I will update when I do the wheel but it will be much later or next fall.

Hmm,
I think I would do this differently, if you connect it to the cigarette lighter in the cargo area and change the fuse to battery then the module would be powered on all the time. A simpler solution would be to use a fuse tap on fuse 58, 59 or 60 to power on the relays which would enable the remote start heated seats/wheel and save a bunch of wiring. Those fuses are the fuses for the factory heated seats and wheel.

So, we are in luck today. I am finally putting the heated wheel in my Jeep. It does matter where the two wires go in the clock spring connector. Cavity 3 in C4 of the comfort module goes to cavity 3 in the clock spring connector and 4 goes to 4. You will need to look at the C4 connector to figure out which is feed and which is return. Cavity 3 is the feed wire and cavity 4 is the return.

4 is the greenish connector on the bottom and cavity 3 is top right, 4 is top left in the photo below.

I have the wiring harness from infotainment.com. I have my seats working but I cannot seem to get the two pinned wires into the yellow harness for the heated steering wheel. Is there a trick to it? They get about 3/4 in then stop.

Any help is greatly appreciated!

You have to slide the yellow sheath off and then lift the white tab/bar about a 1/16 of an inch or so then the terminals will click in. Push the white tab down and put it back in the sheath.

Greatly
Appreciated. Was trying that earlier but I felt like I was going to break the yellow piece.

 

[Gregj]

The sheath is zip tied to the wires and it slides out the open side.

Hi everyone,
first of all, thank you for this thread — I’ve read all the pages. Since the discussion spans roughly from 2022 up to today, I just wanted to double-check in case anything has changed or a faster/cleaner solution has been found in the meantime.

Could someone be so kind to post a quick up-to-date summary of the OEM parts that are commonly used for the heated steering wheel + heated seats retrofit on a Wrangler JL?

From what I understand, I will need at least:

• Heated steering wheel (OEM)
• Center stack / HVAC control panel (climate control panel with the correct buttons)
• Heated seat elements / pads (cushion + backrest, plus sensors if required)
• Steering wheel clock spring compatible with heated wheel
• Seat & steering wheel control module (CSWM / heated seat module), if applicable on JL

Wiring question: for a 2021 European-spec JL, can I use the same harness / wiring solution mentioned in the previous posts, or are there EU-specific differences (connectors, PDC/fuse positions, CAN wiring, etc.)?

Thanks again — I really appreciate any quick guidance.
