So I am going through and redoing some of the electrical on my 1973 Chevy G20 van and I found this plug melted to the side of my engine block. Can anyone help me identify it when I found it the plug that was in it had four wires coming out the end there seemed to all be wired together but then I took it out and subsequently lost the piece with the wires that were together. So I need help identifying what plug this is so that perhaps I can replace it and maybe restore it so it's not rigged all funny

I don't have the answer, but I came across the very same question today on my 73 c20.
And I'd like to share my photo with the same interest.
I have 3 of these connections:
-The one in question is disconnected: What is its function?
-A second connected right into the firewall beside the bulkhead: What is its function?
-A third between the first two: What is its function?

rear lighting harness? do your lights work?
-
Yes my lights work but when I lost the plug my engine won't even turn over anymore. Whereas before it would turn over but not start
-
The wires coming out of it are green, light green, and two brown wires.

Some of the colors you have are standard for the lighting circuit. Take a look at this link. http://www.chuckschevytruckpages.com/80hlightschematic.html

It doesn't look like it's burned beyond use.
Take a razor knife and clean up the burned areas, use some brake cleaner to clean out the gunk.
Then plug it in and get on with life ;)
