Looking for information on the wiring harness and temperature sensor for the electronic mirror. This sensor measures the ambient external air temperature. Installing one in a 2001 Chevy that has the wiring harness in the ceiling, but having a hard time tracing where it goes to see if the sensor is there or I need to add one. Temp. reads zero (0) right now so I don't think there is a sensor hooked up to the other end of the wiring harness. Any help locating where the wires come out under the hood would be a big help. Thanks in advance.
Jeff.
