The parts in the pics are from a '70 Cutlass side marker lamp.

I've seen this same crap soooo many times on 60s & early 70s GM cars. Wiggle the bulb, it comes on. Plug it back into the housing, it goes off. Wiggle the wire, it comes on. Turn the light switch off, then back on, and the bulb isn’t working. So frustrating! It’s now fifteen minutes later. Spray some contact cleaner in the socket: same thing. Install a new bulb, same thing. It literally is the same damn thing all the time. The bulb is loose and the contacts on the bulb are not contacting the wires.

At one point they reengineered this socket to be all rubber and have integral wires, but in '70 you had a plastic housing with removable terminals/contacts. They used this same socket for lots of interior applications too, but the side markers after fifty years are nearly always rusty:





So many terminals are available for lots of applications on these cars; they're plentiful, inexpensive, easy to replace and make for an invisible repair.


Both contacts in this socket were wasted!







I searched the net for an hour and found some terminals that look really close, but not exact. The pictures of them do not allow you to see for sure if they're fashioned for the GM plastic housing.



Does anyone have a source for these that led to success? It would make such a quick and easy repair to just install new contact terminals, plug them back into the housing and be done.

Got a picture of a good connector

 

This is the terminal.

 

I just came across this old post and knew I had the part number saved for these terminals.

Aptiv (formerly Delphi) part no. 12089139

OP likely came up with a fix by now but maybe this will help someone else.

 

Thanks for posting this. I could only find a few companies that had them but they are out there.

 

Are the "side market socket 194" on ebay appropriate? Or the the molded socket visible portion a mismatch? Maybe just extract the terminals and leads from one.
