1JZ ECU Wiring Information
This page details the complete wiring information & pin outs for the Supra 1JZ-GTE powered car.
I do not take full credit for the information contained within these diagrams, this is an amalgamation of incomplete information from various sources across the internet. What I do take credit for is putting in the time & effort to cross reference the limited & random information available, confirming the information by testing it & carrying out more research & tracing to fill in all the missing pieces to complete the diagrams. I have also added where possible, additional interconnection details & system information.
It’s been a bit of a slog but, to the best of my efforts this information should now be 99% correct, complete & all together in one place!
