Hi all! Im new to this forum and I really need some help with the stock wiring in this car.
Vehicle- 1993 lexus sc400 (1uz-fe)
ECU- Megasquirt V3.0 from DIYAutotune
Wiring- Using stock wiring harness and also used a fuse block and a relay thats connected to the battery wire from stock ECU

My question is how do I wire up the stock ignition/distributers to the megasquirt wiring harness.

I have looked at many diagrams showing what each wire does on the stock wiring harness and the only thing I see that has something to do with the distributers/coilpacks/spark is the igniters. For some reason there is four and I have no idea how I can connect that to this MegaSquirt wiring harness.
