Error on GM diagram: 04 Avalance Hey guys. I'm working on my wiring and found an error on the wiring diagram. The AC pressure sensor wire (gray) is on C1 (blue) PIN 45, but the wiring diagram shows Pin 46. Pin 46 is actually for the EVAP. I thought I would point this out in case anyone else might get tripped up.

It could be a 5 Volt reference wire as many of the gray wires are. If you look, you may see that there are 4 pins in a row that all supply 5V reference signals to various sensors. So, even if you swapped the wires, as long as the sensor is getting the 5 volts, it is going to work. Just a thought.
