I have to replace my alt, when I removed the old one the pig tail (3 wire)) disintergrated. I got a new one from Napa, but all the wires are black. Does any one know how to match them to the alt. One is larger and the red wire on the car is larger so I will connect these together, but the other 2 ?, Thanks Steve '93 Anniversary ED.

 

Get a continuity light or ohmmeter and identify which pin on the plug each wire went to and connect the new one the same. If that doesn't work get a wiring diagram that gives wire colors and pin locations and follow that.If all else fails find another 93 and copy it.

Here is a wiring diagram

The car has 235k and runs great, a few leaks but that's it.
