Hello,

Well, swap is underway. Putting in a 1993 J-spec 2jzgte from a supra into a 1993 SC300. I have the FSM for the sc300, and I found everything I needed to know about the supra wiring , such as which wires go from the ecu to the dash interface a.k.a Combination meters such, and the main ignition wires (this includes JDM wire colors and designations).

This being said. I cannot find which plugs I need to swap from the SC300 and what each wire represents. Any help would be great. (I'm looking for plug designations such as IJ2 and such) I thought I could just follow the ECU pinouts and come up with the wires I needed, but it seems that there are multiple wires with the same color and gauge. I try to follow the FSM, but it is so confusing and I get lost in the maze of diagrams.
Any help would be appreciated.

Thanks in advance.
