81 alternator wiring
hi there everyone im doing a 100 amp swap onto my 1981 c3 it has a 4 wire plus 1 ground and 1 to bat setup on the new alternator and i currently have a 2 wire plus ground and positive to battery. i have done a bit of searching and found 2 different diagrams... im wondering which i should be using to do this swap? the new ALT has PLFS on it just for reference.

i have a rebuilt 4 wire alternator just sitting around and instead of going to buy an oe 100 amp online and have to wait for shipping (the only thing i can get locally is a 63 amp.) i was going to use the 4 wire alternator i had laying around.

All you need is an adapter pigtail to go from stock wiring to a CS130 plug.

This is the one you need since your car has an indicator lamp.
