trebor69 Posted March 15, 2015 Share Posted March 15, 2015 (edited) A lot of people are looking at doing this but are unsure of the wiring procedure, below is a list of my notes after successfully completing this conversion. These notes are about 97% accurate as I think I changed a wire or two but can not be sure as to which but I can guarantee that the car WILL run wired this way, the only thing that doesn't read correctly is the dash temp gauge (I have fitted an aftermarket temp gauge and now use that) There are 5 Soarer plugs that need reducing into the 3 Supra plugs. These notes are as follows.....Soarer plug orange 23 pin to Supra plug colour and pin number: SOARER ORANGE 23 PIN 1 pink/black to Supra orange plug 21 2 green/yellow to Supra grey plug 17 3 grey/yellow to Supra grey 13 4 turquoise to grey 5 5 green/red to grey 6 6 red to orange 8 7 blue/red to orange 2 8 black to orange 29 9 yellow/green to orange 24 10 to orange 12 11 red/black to orange 36 12 grey to orange 7 13 blue to orange 1 14 green/white to orange 18 15 not used 16 green to orange 17 17 white to orange 27 18 blue/yellow to orange 15 19 white/red to orange 6 20 yellow/black to orange 25 21 green/orange to white 3 22 grey/red to orange 5 23 purple/red to orange 33 SOARER WHITE 25 PIN 1 black/orange to grey 9 2 blue to grey 16 3 4 5 6 7 8 9 green to grey 19 10 11 brown /black to grey 18 (this one and 23 below need checking) 12 13 14 15 16 17 18 19 20 21 22 23 brown to grey 18 24 25 purple to grey 15 SOARER GREY 14 PIN 1 green to grey 8 2 red/blue to orange 20 (needs checking with soarer white 12 pin plug wire number 2 below) 3 black/orange to grey 1 4 5 yellow/green to orange 34 6 black/white to grey 7 7 black/orange to grey 9 8 pink to grey 12 9 10 yellow to orange 23 (needs checking with soarer grey 17 pin plug wire number 13 below) 11 red/yellow to orange 32 12 black/red to orange 13 13 14 red/g to grey 4 SOARER GREY 17 PIN 1 red to grey 3 2 white/red to white 10 3 pink to orange 11 4 5 6 green/black to orange 4 7 green/white to grey 11 8 9 brown/yellow to white 11 12 13 black/yellow to orange 23 14 15 16 green/red to orange 14 17 SOARER WHITE 12 PIN 1 2 to orange 20 3 4 to orange 26 5 to orange 31 6 7 8 9 10 11 12 These are the notes I made and worked from, please update this thread with any corrections or additions regarding air-con etc. I hope these are useful to anybody thinking of doing this conversion.

trebor69 Posted March 15, 2015 Author Share Posted March 15, 2015 I'm pretty sure that the blanks have no wires in those locations at all, not that I'm not sure of them but the Soarer plugs do have a lot of unused pins. Quote Link to comment Share on other sites More sharing options...

trebor69 Posted March 16, 2015 Author Share Posted March 16, 2015 Comprehensive list of the Supra pin outs and functions there Lyndon, Thanks mate. Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted March 18, 2015 Share Posted March 18, 2015 Yeah, will help people do other conversion like 1uz's and the like. EA2 I think must be a Canada or US spec fuse box connector as I've never seen one. I didn't mention that the CF, CI and CH codes refer to the 1jz Soarer connectors.

Hi, I have a Lexus is200 and currently in the process of putting a 1JZ into it, the 1j was originally from a chaser and then was dropped into a mkIV supra, For some strange reason the guy scraped the car, from what i could see it was mint but I got the engine and it was mostly wired for a supra with an EMU standalone... Anyway it has the orange 38pin and grey 20pin from the above list and i have been rewiring it accordingly, what i casnt work out or find out is where orignally these plugs would have been in the supra? where would they normally plug into for the supra, its just thrown up some confusion as there are a fair few wires in the wrong places, injectors where wired up all wrong along with a couple of sensors and the VSS. Thanks for your help Quote Link to comment Share on other sites More sharing options...
trebor69 Posted October 15, 2015 Author Share Posted October 15, 2015 Only just spotted this post, all the blocks connect to the supra wiring in the passenger footwell, ecu to the right and all other block connections on the left. Quote Link to comment Share on other sites More sharing options...
RTurner93 Posted September 12, 2017 Share Posted September 12, 2017 A lot of people are looking at doing this but are unsure of the wiring procedure, below is a list of my notes after successfully completing this conversion.

Hi mate can you answer why pin 7 on soarer grey 14pin orange and black goes to supra grey pin 9 but also have another wite going to the supra grey pin 9 the soarer white 25pin plug pin 1 orange and black? Do you join both to same pin 9? Thanks Quote Link to comment Share on other sites More sharing options...

Hey mate just a quick one. Probably a stupid question. But did you use the 2jz ge ecu? Thank you for your time Quote Link to comment Share on other sites More sharing options...
trebor69 Posted September 25 Author Share Posted September 25 Hi mate, no I used the 1j Soarer ECU that came with the engine. Quote Link to comment Share on other sites More sharing options...
