Hey all. I am almost done with my 1jz swap into my s14. Have completed the wiring of my lt12s. And I am onto trying figure out the alternator wiring. It has the 3-pin connector. With this being a custom harness and a standalone. I have to make a harness for the alternator from scratch.

Can u guys explain the wiring to alternator? What the wires are I need for it to function and which pins.

Here is a pic.



there is also this plug coming from being alternator anyone know what it is?
