Rear seat heat wiring info needed

[Tbruz]

Decided Im going to operate my aftermarket seat heaters by wiring them into the denali/escalade rear seat heat switches, that way the switches will look more GM factory-like and illuminate as well.
Got the pin outs for the aftermarket ones but need the factory wiring info.

Does anyone have the wiring info for the denali/escalade rear seat heat switches?
Thanks in advance
