I'm want to replace the 4 pin connector in the harness for the heater motor.
Years ago I saw a male/female part that you spliced into the original wiring for the repair.
Using Google I can't find it.
Maybe someone can direct me to it.
Thanks

The plug and jack has three 16 gauge wires and one 10 gauge.

Not sure if a weatherpack will accept a 10 gauge, they sell the pins and separately though so you can configure the plugs however you need to. If you need some tech help call quickcar they will know (most of the electronics stuff allstar has is made by quickcar)

But I saw a replacement plug/jack.
It might have been from a member here that makes up harnesses.
But I don't remember his name.

No that's the plug that goes on the resistor for the blower motor.
The one I want is on the harness that goes to it.
It's large white square male/female plug.
10 gauge red wire gets hot and melts at that connection.

I guess there are other no leads to finding what I'm looking for ?
Really don't want one from a donor car if I can help it.

I don't think you are going crazy, I remember seeing it for sale too, and thought about buying one as I could tell mine has gotten warm in the past, but I can't come up with it again...


Sometimes you just need a bigger hammer...

OK contacted Pico wiring, they don't make the pigtail connector.
Found the connectors are the Delphi Packard GM 56 style.

I found this on Ebay:

https://www.ebay.com/itm/DELPHI-PAC...84440384?vxp=mtr&hash=item542a26d340

The three 18ga. wires are still in the original plug, it's the 12ga. that got hot and was the problem.
Going to swap out the 18ga. wires into the new connector and put new 12ga. terminals on the larger one.
The plastic connector itself is used for small and large gauge wire.

P.S.
Wanted to post pictures of problem but don't how to do it.
I thought the icon at the top that looks like a picture would let me attach a picture from my files but it was no help.

Nice detective work!

When replacing the pin on the red wire, you may have to strip it back a bit to find clean wire, as it most likely got hot due to corrosion.

A great idea, it'll certainly be black from the heat, good luck!!

Yes I've done that already.
I used a butt connector that is shrink wrap type for the repair, but I want to install the correct style connector that isn't melted.
It has bothered me from the moment I did the repair.
