Need Firewall harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jtminton · 05-02-2005, 09:25 AM

While trying to figure out why my temp gauge wasn't working, I have discovered that the harness that the sender plugs into on the engine side of the firewall is melted from some electrical fire of yore. Does anybody have a plug with some wire on it so I can splice it onto the existing wires? From what I can tell, there are two plugs, one that's sort of a rectangle and one that is shaped like a backwards 'C'. I need the rectangle one. Here is a picture with an arrow pointing to it. Thanks!

It doesn't have to be pretty . . .

One is your forwardlight harness and the other is your engine harness.Besure to tell us if your truck has the deluxe gauges or just warning light for there is a difference.Also year model would help too!

Sorry I forgot that. It's a 72 C-20 with gauges and a factory tach. I guess I need the engine harness plug.

I'll check the one I removed from my 72 C20 later today.

I left a message, but never got a call back. What do you want for that shipped to 76036?
