(Don't know if thiss will help because my car isnt running yet), for some reason the junkyard cut the alternator harness so i ordered a replacement connector that came with just one wire, the alternator should have a 12v battery wire and its case gounded, voltage regulator is built in, so it should only need one wire to power the coil, and i think the other wires are for voltage gauge and to turn off battery light when its charging not needed unless your car came with an ls1

If you put a one wire regulator in it.
One wire alternators only have a battery connection, the regulator is self-exciting, so it needs no other connections

Ok, mine also had the one wire harness. Would you put that wire to a key switch to excite the coil?

Anyone else have a take on this? If not, what other alternators could I use?

The one Wire goes to the PCM.. my 1999 Harness is a one wire Harness. I spliced into it for the Gauge Signal Wire for my stock Camaro Gauges.
