Are you saying all GPs or GTPs came prewired for the auto-dim mirrors? And even if the 3 pin wire is there, he will need to wire the temp sensor in separately. The 3-pin wires will just cover power to the auto-dim and compass/temp display, the ground, and the disabling auto-dim in reverse feature. He will still need to run a wire from the temp sensor to get an actual temp reading, and I believe a separate negative is also required for that sensor. 4th, the temp sensor you're referring to, is it for the digital dual climate control?
