Hi to All Did a search but not much found. The 2JZ Supra loom alternator plug has 3 wires that go to pin 23 and 34 of the orange connector and a white going to the 3 pin connector engine to body plug. The MX83 has 3 heavy gauge wires from the engine bay fuse box to the alternator plug. What is the best way to conect up the 2JZ alternator in the Cressida, extend the MX83 wires to it and 2JZ Alternator Wiring.. What Colour Goes Where Yo dudes, Because I don't have a pot to piss in, I'm using a 2JZ-GE alternator from a gs300, on to my Soarer 1JZ. I'm going to wire it so it charges all the time, ie wiring straight to the + post, thats irrelivent ATM though..
