Im hoping someone here can help with a fairly large issue I have. I currently Own a 1986 Toyota Supra and recently obtained the 1JZ engine/tranny/wiring harness & ECU from a 1991 Lexus Soarer. I have checked thru both the local Toyota & Lexus Dealers and neither can obtain the information i require to complete this mutant motor change i have going. The main reason for not being able to get what i need from the dealerships is that this particular car is a Japanese spec car, not offered in the USA. What I require is the wiring diagram for the Soarer that tells me what color wires go where from the main engine wiring harness to the internal harness of the car. I would be very appreciative of any assistance here.
