Thread: GM Power Seat Wiring

Tweet

I have a set of 2005 Cadillac CTS Power Seats and need help with the wiring. I need a wiring diagram for the seats and seat heaters. Any help would be appreciated.

Thanks,

Ken

I've been working on 2002 Buick seats for my F100. The nearest I've found (without paying for it) are seat diagrams for a 2003 Pontiac. The Caddie should be pretty close because the're all GM. check this link -

The passenger side was no problem, just connect power and ground. The drivers side is another story...

The drivers side controls go through a circuit board which controls the seat position from memory. I had to bypass the memory circuits and connect the controls directly to the relays on the board to control the position of the seat. There may be an easier way, I don't know.

Good luck,

I suspected an issue with the memory functions. Do you have any more info on how you wired around the memory circuits? Any details could save me some research time.

Thanks,

I tried the passenger seat and no problem, just like you said. After taking a closer look at the diagram and my driver's seat, I connected 12+ to the small red/white wires in the seat connector to power the memory module and it worked. All the functions work just great. Now on to the seat heaters.

Thanks,

Ken
