2002 Deville Dash diagram
 

Hello fellow owners.
Am brand new here. In herited a 2002 base modle Deville from my uncle.
122,xxx miles, instrument panel was total busted up and came out in about 120 peices.
He had a coffee can and two sticks propping it up. I found a used one with only two small breaks that
I was able to repair and it is now installed and looks great.
When I opened it up to start removing stuff for the replacement of the plastic portion of the panel, I found a white plug
laying loose on top and forward of the right side bolster panel.. Nothing obvious and the heating and ac work pretty well
so it must be a control for a rarely used item.
Anyway, trying to find diagrams on the car for this area and not much luck on finding a quality diagram.
The male connector has a label on it with information. Am going out to take pics of that area and will either edit this
original post or just ad below if I can't figure it out (remember, am new here, lol).

OK, I am back with some information ans hopefully pictures. The connector has a paper lable near it that is identified as 50154. It is a 6 pin male connector with only two pins used. The first is purple and the 2nd is green. The wire bundle has a label identified as 0819 and there are no other connectors on this particular bundle.
I looked everywhere around this area and can not find a box with a connector missing. If I could find a quality diagram I may be able to identify this connector.
I know that in the aviation industry there are many connectors that are part of the basic harness and they are stowed with a cap and labeled for their intended usage. That is in case that standard but optional equipment is added
down the road that harness is there and ready to go with the exception of adding a circuit breaker or fuse for the new device. Not sure how GM did this.

Only two wires, guessing glove box light? Check with multi-meter.
