Wrong Door Harness Suggested

[Juan Andrés Del Moral]

So I bought some new towing mirrors from gmc that required me to change out the door harnesses for both sides in order for the lights on the mirrors to work. I was told to get gmc part #84622369 for the driver door and gmc part #84622370 for the passenger door. 
 

I got the mirrors installed perfectly. 
 

I got the driver harness installed and all 7 plugs plugged in like it was supposed to. I get to the passenger side and the harness has a different plug for the power window regulator. The original harness has 7 wires as did the new driver side harness ending in 2369. The new passenger harness power window plug only has 2 wires and will not fit. I have contacted all the local dealerships around me and all of them say the same thing. That I have the right part.  I do not know what the wiring diagram looks like bc I messed up the pins from the old harness taking it out so just cut wires before noticing the wrong plug.  Black and blue plug is wrong plug.  Gray plug is what it should be.

ask to see another harness if they have 1, possibly it got marked wrong at the factory where the left side was correct. you may be able to pull up a picture with some research too

I’ve been googling the part number for pictures and haven’t had any luck and the part is hard to find bc no one locally has it in stock.

Your pass door has an auto down AND up regulator.  That door harness is for auto down only regulators.
