So, I have the vehicle listed above C10 deluxe. I bought a new heater switch panel but my wiring on the new panel doesn't match up with the OEM wiring so I was just wondering if I could get the wiring diagram for the heater switch panel, please and thank you

Hi,

I suspect this is an 81 since you indicated that in the post. If it is a 91 (heading), let me know.

Because of the model year, 1981, my resources are very small. I found a schematic of the dash and instrument panel. The only thing I am seeing is related to the fan switch. I have a 1978 and other than a light, which is the only electric to the controller.

The page this came from was huge and extremely difficult to follow. I highlighted the areas that may help you. Let me know if it helps or if you have questions.

Take care and Happy Thanksgiving.

Joe
