Wow! That was quick.

I am trying find an accurate wiring diagram for it, but my searches were in vain. Those boxes do look quite old.

The wiring diagrams I did find, seemed similar in wire positions but the color of the wires didn't match up. Just hate to invest a lot of time in guesswork wiring efforts.

That plug is ancient... A newer harness would probably be a good idea...

Ordered the wiring harness . When I took the old plug off, it was definitely corroded on the center contact. Thanks again for your help.
