Found open connector near BCM do not know where it goes... Any thoughts?
 

Hey guys, I was removing my overflow reservoir to clean it out because it had that brown sludge built up at the bottom. While I was unbolting the BCM from the resevoir I noticed this connector that was disconnected and I cannot figure out where it goes. I was wondering if any of you can point me in the right direction. I have attached a thumbnail of what I am talking about. Ever since I had my 02 Blazer Xtreme, the headlights never worked. Could this be the connection to the BCM that is preventing the lights from grounding? Thanks everyone who takes the time to look through this.

The ECM is bolted to the reservoir. The BCM is located in the cab.

Not sure about that plug. I'll check AllData when I get to school in a little while.

It looks like it is just plug terminated meaning that it has a dummy sealed plug installed into the end of the connector. It likely is for a feature that you do not have.

Anyone know “feature”/use of connector? I recently discovered it also (2dr 2wd ‘02)
