Ohshi7 Posted August 20, 2019 Share Posted August 20, 2019 Hey guys, i have started working on my 95 Supra, Basically im looking for a wiring diagram to re-pin my 1jz harness into my 2jzge body harness. I know it has been done before but i can't seem to find anything on any of the forum sites or if i do it usually has been deleted. If anyone would be able to help that would be incredible as im trying to finish the car up as urgent as possible. Thanks Quote Link to comment Share on other sites More sharing options...

Konrad Posted August 22, 2019 Share Posted August 22, 2019 Everything you need is probably here: http://wilbo666.pbworks.com/w/page/41678224/2JZ-GE%20JZA80%20Supra%20Engine%20Wiring I used this to make harness between 1jz engine and 2jz internal one without cutting single wire Quote Link to comment Share on other sites More sharing options...
Ohshi7 Posted August 24, 2019 Author Share Posted August 24, 2019 Essentially I wanted to re pin the connectors, will it be one of those diagrams where I need to match either wire to the same sensor ? ( If that makes sense ) Quote Link to comment Share on other sites More sharing options...
Konrad Posted August 24, 2019 Share Posted August 24, 2019 its more about matching what's on the end of 1JZ engine loom with what you got inside Supra (Orange and grey plug mainly) Quote Link to comment Share on other sites More sharing options...
Ohshi7 Posted September 8, 2019 Author Share Posted September 8, 2019 So I basically have started matching the pins to each other on the both diagrams but Ive run into a road block, with about 10 wires would you know which ones go where if I was to write them down on here?

Ohshi7 Posted September 16, 2019 Author Share Posted September 16, 2019 So has anyone been able to crack the code yet? Quote Link to comment Share on other sites More sharing options...
Shane Posted September 16, 2019 Share Posted September 16, 2019 So has anyone been able to crack the code yet? Those numbers mean nothing to me I am afraid. I recently did a 1uz conversion into a 2jz gte, ok not the same I apreciate, but principle the same. Using the 1uz ECU pinout and the details in the Wilbo666 link I was able to wire the whole thing and that was without half of the connectors from both the 1uz and the 2JZ, so assuming you have pinouts for both models you should be able to cross reference what goes where. If you have all the connectors from both cars it should be even easier. Quote Link to comment Share on other sites More sharing options...
