jumpbike Posted October 19, 2013 Share Posted October 19, 2013 I've searched hi and low on the net for full wiring diagrams for a 94 JDM 2jz gte from anything really, I have an engine with full loom hanging off it but it still has all the old loom for the lights and everything and really I just want a diagram so I can follow wires back and find out what I can rip out. Im hoping to pick the loom from the vehicle its going in to keep the vehicles original lights, AC wiring etc. but i'll need some sort of diagram to splice the looms together for the dials mainly and any other things that usually go to the ECU etc. thanks people, hope you can shed some light on this.

If you mean ECU when you say computer box? I don't think there is anything you can do apart from swap it or place a wanted ad for a 2JZ GTE one.

Guest ALLAN 2JZGTE Posted October 20, 2013 Share Posted October 20, 2013 Ok thank you so much LoGie much appreciated iv been struggling with it cause iv heard there is a way of using the 1jzgte ECU for the 2jzgte engine but I don't know where to start maybe if they can upgrade the software on the 1jzgte ECU is that possible with a Diagnosis machine or dyno tuner?
