Looking for a brake switch plug 79 C10

[chrismoore701]

I have been having brake light problems for a while now, narrowed it down to the brake light switch plug. I have a 79 c10 frame off with a new painless harness. I believe I used the original plug for the brake light switch. it looks fine. Measured for continuity across the switch and it works. Measured 12 V for the power side of the plug and all good. connected plug, pushed brakes, no power to the other side of the plug. removed wires from the plug and connected straight to the switch. All is good. I have no idea.

Anybody know where I can get this plug?

Advanced, Autozone, local hotrod shop, classic parts of America and LMC, no good.

I can always just connect insulated connectors to the switch, but would like to have it correct.

Thoughts?

thanks
Chris
