1978 trans am carb ls2 alternator wiring question
I have been reading and searching for days now and I can't figure out how to wire up my new powermaster 230 ad alternator into my original wiring harness. i bought the holley pigtail for that alternator to connect to the brown wire (i-field). see attached picture. I know to connect one red wire from the battery to the lug on my new alt. My question is where do I connect the red wire (sensing) on my new alternator? Also, what do I do with the third red wire that is with the a/c line conn in the picture. Those two red wire (sensing and the bottom one) connects together in a 4 wire splice with 2 wires going to to 2 different spots on the bulkhead connector. if that is too confusing, let me know.
So what I have done so far is cut away that 4 way splice. So i have 2 wires coming from my harness going to FZ and CY on the bulkhead connector. I do not know where to connect them to my new alternator.
Thank in advance for any advise.
