Default Alternator wiring 2003 sc430

Hey can anyone please help me. My car has been down for over a month. All because I was changing the alternator out and the pigtail snapped. The connector broke. I ordered a new one. I don’t know how to wire it up. One of the color wires are red and blue. Yellow. I can’t remember the other color. There is no black. Once again I need to know what colors go in what order. You help is greatly appreciated

Yes, the aftermarket replacement plug pigtail assy's I see have Red, Green and Black wires.

Here is the info from my 2004 SC430 Electrical Wiring Diagram manual.




That should help you get the wire order/location correct.
