I am rewiring a 2003 Neon away from stock PCM which has the alternator voltage regulator inside the ECU. What would be my junk yard donor for an external hi-side regulator and it's pigtail?
If I just put the field wire to Vbatt I get 16 volts and too much load. I want to stay with stock harness so I do not want to change it to low-side regulator.
Just about any 80's or earlier carbed mopar should have a solid state flat pack regulator in it.
this link has good stuff in it on how to hook it up right.

New regulators are super cheap from rockauto, they also have the pig tail.

Right. The part I am confused about is that some of them the field wire goes to ground and some of them the field wire goes to battery - say 1st gen Neon field wire is PWM cycled to GND and 2ng gen neon field wire is PWM cycled to VBatt.
I see some $10 voltage regulators on rockauto and the 2-wire connector is under $5, that's pretty close to what I am looking for - the only downside if that I would need to ground the regulator case with a 3rd wire but I can live with that.
If there are 2 field wires ground one of them on your alternator. The second connection is ground on the v/r , use chassis ground and the third 12V goes to the input of your fuse box hot side. Easy pie.
swap in a GM alternator... there's gotta be a CS series alternator that isn't too hard to physically bolt up..
