I'm currently building a 1977 K5 for my son's first truck. I picked up a set of leather LTZ seats from a 2010 Suburban, fronts and 3rd row. I'm trying to figure how to wire the driver seat heat. Anyone done this swap and have the heat working? Does anyone know how to wire in the temperature sensors?

Here's what I've figured out so far:

Driver seat
- Larger gauge red/wht and smaller gauge red/wht are power (+)

- Larger gauge black is ground (-)

- This makes the forward, backward, up, down, recline, and lumbar work.


Passenger seat
- larger gauge red/white power (+)

- larger gauge black negative (-)

- larger gauge dark blue power (+) for heat butt/back

- larger light blue ground (-) for back

- larger gauge pink ground (-) for butt

I have no idea on the specifics of that seat, but usually there's no temperature sensors in seats. They're usually thermally regulated. They only get as hot with how much power you throw at them. 14v is full tilt heat. If you measure the resistance of the heater, you can calculate how much heat it puts out. Assuming 13v for an older alternator with accessories dragging it down a little, I=V/R which gives you the amps through the circuit. Then you can calculate watts, W=V*I. You can increase or decrease the amount of heat with a 5-10 ohm variable resistor.
