i need help. 84 4x4 pickup. alternator problem
i have a 84 pick up i just bought. ive been giving it its tune up and noticed the alternator wiring got chewed up and exposing the wires threw insulation. i decided to rewire it and the alternator plug fell apart on me. i have no idea where the wires go. its a 3 pin connector that i cant get ahold of. im just gonna use seperat connectors to wire the thing up. if anyone can shoot me a pic of the socket and what wire goes to which hole or if you just know. id be reallllly thankful. it isnt the round black connector. its the round to squarish connector. ive been calling all over.

just an fyi is that this was posted in the Pre '84 folder but no biggie.
saw this over on another forum, not sure if it will help or not (it was for a alternator swap but maybe the plug pictures will help):
good luck

I did this mod on my 82 Pick-up and it works great!
The early 22R's pre 84.5's run the 40 Amp externally regulated alternators.
While the 85+ 22R's have the 60 Amp internally regulated alternators.
Comparison photo, the early model alt is considerably larger.
The lower engine/alternator mounts are different, sorry I don't have pics of them. But the older 40amp alternator is mounted in a "female" fashion, while the older mounted in a "male" fashion. The upper mount/adjustment point are the same on both alternators/engines.
The wiring harness from the alternators to the fenderwell plugs are also different. They both are wired differently and have different plug patterns. The only mod necessary is on the fenderwell wiring:
-Carefully remove the 'cover' on the top of the plug(no pic again!)
-Pry the wires out the back of the plug
-Eliminate the external regulator with wiring, LEAVE enough wire to splice into the alternator connection.
-Simple color coordination here, just line up the colors with the coresponding color on the "new" alternator harness. yellow-yellow red-red black-black white-white
-You will have a extra yellow wire after you splice the new connector, I just spliced it into the other yellow wire. PIC
