Wiring harness advice

Hey Mattax, the replacement alternator I had was a squreback with both isolated brushes, but rebuilder had used a brush holder that had grounded one side to simulate a round back alternator. I pulled the grounded brush holder off and swapped one from another alternator on to make it an isolated field alternator like it was originally designed.

I guess round backs are getting hard to find, so they just convert newer ones now by grounding a brush to sell for the older cars. Since my car is kind of a Frankenstein any, I didn’t care.
