Broken Connector
 

Tonight I took a back road to get home and my CEL came on about halfway. It was pretty icy and there were some rather large puddles with maybe a half to 3/4 inch of ice on the top. Anyway, I get home and check it out and a connector that appears to go up the drivers side of the tranny and runs along the cross member must have come loose and snagged on something. I can't figure out what the wires (it is a gray 4 wire connector) go to. Searching the board using keywords like 4 wire connector near transmission cross member and different variations larger and smaller didn't give me anything useful results. Can somebody help me out and at least point me in the direction of what it is that got disconnected? Engine runs fine, she drives and brakes fine and the 4wd still worked afterward.

Thanks
