Hey guys, new to the forum here. Recently bought an 07 1500 classic, the truck was a rebuild and whoever rebuilt it decided they didn't need the cabin air sensor in the headliner above the driver, anyways I ordered the sensor and harness because they cut the factory conntector off. But on the replacement connector all 4 wires are grey and And the factory harness has black,brown, white with black strip, and a green wire. So I need to know which color wire goes to each pin on the sensor. I've been all over the Internet and can't seem to find a wiring diagram anywhere. Thanks

 

the headliner inside air temp sensor
4 wires
a-dark green
b-white/black
c-black
d-brown

the connector should be female. with connector facing you, lock at the top, longer nub of the connector on the lower right; the order of the wiring is a b c d reading from left to right

 

Thanks for the quick reply, just wired it up and it seems to be working right. Nice not having to set the heater on 90 to get any heat out of it
