Esprit-SE Posted June 7, 2011 Share Posted June 7, 2011 Has anyone swapped out the main 3 pin plug to a differnt style connector on an SC alternator before? I am trying to splice a 1992-94 style connector onto my 1995 SC 300 main harness so I can install a 92-94 fitment alternator.. The plug I have (that I am installing) is a round connector with the triangle stlye pin lay out, but the wire colors are totally different than the newer oval connector I have. (It might not be from a 92-94 SC Lexus originally)... The 95 main harness plug that WAS on my car has 3 lined pins (black wire w/yellow stripe, solid white wire and yellow wire w/green stripe... The oval harness plug I was given to swap to has a really thick gauge white wire comming of it with a green stripe, and two smaller guage wires (a red wire with a light blue stripe and a yellow wire with a light blue stripe) .. In short, I am not sure which wires to splice together from the factory 1995 car into the 1994 & prior style plug. I dont have a manual, so its a guessing game.. Any pictures or ideas guys???

Esprit-SE Posted June 7, 2011 Author Share Posted June 7, 2011 A wiring diagram would be phenomenal if any one has one. :) Quote Link to comment Share on other sites More sharing options...
Rocketrod106 Posted October 19, 2019 Share Posted October 19, 2019 I did this same swap last summer. I bought the pigtail needed off ebay. The listing included it’s diagram. Then I googled the diagram for the connector for my car’s year make and model. Cut and spliced accordingly. Hope this helps. Quote Link to comment Share on other sites More sharing options...
