I wanna install the Temp/Compasss mirror in my 2002 Sierra, its has all the wiring to attach the mirror on the inside, but I cant find the wiring under the hood, temp sensor is suppose to be mounted beside the driverside headlight.

Does anyone know if there is a separate wiring harness that can be purchased from the dealer, or where it connects to the forward Electrical Bus.

Any info would be greatly appreciated

Thanks Ian
