Here's a couple of pictures to give you a better idea of the area. All of the pictures are of the same harness area. The two wire connector is one blk wire and one yel/red tracer wire ( old wiring, taking my best guess at colors) and the clip on wire is to the oil press send. Unit iirc its also a yel/red color of wire. That two wire connector and the sender clip on connector go into a grey connector, and that is where you see the blue wire that is cut, and then continues into the main harness on the Dr. Side. Hope this helps a little more.
Pic above is a clear shot of the two wire connector, and the one wire sender clip on connector, that goes into the grey connector that shows the blue cut wire, then continues into the main harness.
