So the interior cabin fuse 16 is not powered until remote start or running. Tape a fuse add a circuit will be my solution for the 12v power

Thank you!!!👍

A member is posting wiring for 2026. Interestingly c200 is the bottom harness now. Where as the original post it's the top harness. It's still the same pin number 38.. 2025 c200 is still the top. There's no yellow/green wire running to it as previously reported.

Thank you! Huge help

Do you have the pin out information for c200 and c201?

Does anyone access to the pinout diagrams for the various 2025 models? I'm looking for the wiring information for 12v power for the heated steering wheel. It seems they change the pinouts and maybe even the wiring from the fuse box on yearly basis(?). (Should be in that driver's footwell...

That's actually helpful. Hopefully stays true. Thanks

I'm messing with a 2025 XL. Your harness at least looks like mine. Did you ever figure out what wire or pin number?

Ah and I almost bought a new sccm! I too have a leather wrapped from doing the adaptive cruise. (Buying a wheel with buttons cost same as buying buttons!) But since I'm stubborn. And you've already ventured a bit. Can you tell me how you got the 12 volt power from fuse 33? There is a fuse...

Sorry for such a late reply! Did you use the newer sccm part or the one listed in this thread? What's pmi through fdrs? FORScan won't work?

Thanks I'll figure it out

I did the cruise control upgrade a few months back and put a leather heated steering wheel on. But never did the clock spring sccm. Can I use any of the ones with the heated out put or does it have to be DA one? Also did you buy one with the switches (blinker and wipers) attached or used...

I thought this video was linked in here already. But it was extremely helpful. I think that man.

I did get it all working. But Ive noticed when not using cruise control the lane keep assist doesn't really work. Sometimes it steers the truck back, but it doesn't vibrate the wheel like it did before and it often doesn't do anything for course correction. Wondering about the settings, if...

Did you get your 25 working? Can you explain to me the wiring? The original post is confusing to me. The wheel needs just 12v positive and a ground/negative? And the rest is already in the harness? (I understand the clock spring needs replacement). Thanks

LB5T-9E740-AE is the steering wheel switch I have. So I don't know why the code lines didn't work. But easy mode for the win

Helpful trick: For anyone going through the dash with the wires. If you roll the rubber boot back push a straw from a refillable cup in to it and then roll the rubber back you can easily feed through the rubber boot without cutting.

Just did everything except calibration drive. It's 1am... My steering wheel buttons while parked, don't seem to do anything including the mute button. Is this normal and will clear once I calibrate? (Also the buttons came with a heated steering wheel so could be the wrong ones...) Thanks
