What is the 4 blade connector called 1991 GM

[stinkydogfilms]

Hello,
I would like to know what this Male-female connector is called? It has 4 rectangle blades. It is between the DS fender and the PS pump. The wires are
1 big yellow
1 small green
2 big black wires with pink stripes.

Ooops the single wire is my computer cable.

Thank you,
Mike

Looks to be part of the alternator charge harness. I don't have an exact name for the connector though.

I don't think it has a special name, and I doubt you will be able to find one new. That is another weak spot in the 2G charging wiring, another push-in connection for high amp charge wires

Usually that connector is crumbling apart. I replaced that on mine with heavy duty heat-shrinkable crimp connectors, which also aren't the best for a charge wires, but mine was falling apart to the point where the metal spades where almost free to move around and touch each other.

You can get rid of that altogether with a 3G swap, which is practically a 'standard' upgrade anyway

+1 alternator harness. I threw mine in file 13 and upgraded to a 3G alternator.

Old 2G alternator harness. That is a potential fire hazard....3G swap time.

I did a 3G swap on my dad's 91 last year. The plug on this harness literally fell apart when I unplugged it. I could tell it had gotten hot. 86 yours before it causes trouble.
