Im gonna be doing the 2jz swap for a friend in his 91 ma70 coming up shortly, I will keep track of the wiring diagrams and even generate some good wiring diagrams just to add to the existing info present.
Wiring the 2jz into the ma70 chassis
- Thread starter shaeff
- Start date
I've been looking into this swap for quite some time now and have just recently on my searching of posts and thread travels got confused.
I have purchased an aristo 2jzgte with complete wiring harness and ecu, and plan on putting it into a usdm 89 mk3 since i have these items, wouldn't the only thing i need to do is extend the wiring harness and mate the ma70 body harness to the 2jzgte ecu by getting the pin outs for both 2jzgte 7mgte ecu's and matching them?
Or am i completely wrong and there is more to it than that? I will not be using such things as A.B.S and AirCon, Cruise etc and will just plug up what i need.
If i am far from what is to be done please don't set me on fire, just not sure on what exactly is needed.
Jus need some steering into the right direction. Thanks
Ps. i know about the oil pan, tranny housing, and mount issues

I'm doing the same conversion in my '89 but using a 2jzge and adding an aftermarket turbo despite the lack of turbo internals. Does anybody see a reason why that would change the wiring much? I believe they are the same but I could very well be wrong.
HI there i could really use some help iam geting ready to do a twinturbo 2j swap out of a soarer in to my mk3 87 i need all the swap info i can get if you dont mind helping me .?
Didn't see it on here but if your not good at electrical stuff or wiring at all you can always go with Dr. Tweaks. He makes plug & play harness. You'll have to send the 7MGTE & 2JZGTE harness (or whatever you have) if I'm correct. Haven't done it myself yet but I'm making plans of going 2JZGTE on my 87 & i researched & found him.

I had my harness done by dr. Tweak and I can recommend him. It is really nice to know that after all the hassle of swapping in the engine you won't have to worry about it starting due to electrical issues. Mine started in the first turn of the starter. Great service.
Is it all just basically making the body harnnes plugs match up right? You cut the mk4/aristo body plugs off and match the ma70 body plugs accordingly?
2jzgte needs a tach adapter correct also? Or can that work no problem?
Also off topic, but can you use mk4 mounts that bolt to the engine or do you have to get bic mounts or such?

1)You leave all the ECU plugs intact. You take all the MK4/Aristo body plugs off and mate your MKIII body plugs to the MK4 harness.
2)The tach adapter is not need if you are doing a swap on a turbo model. The NA tach will need a resistor removed and there is a write up on here on how to do that.
3)If your car is 89+, you can use the MK4 mounts with the 1JZ brackets. If you car is 86.5-88, you will need the BIC swap brackets.
Exactly what i wanted to know and what i thought.
But just to clarify. i have 89 turbo car so i will need these since i still have 7m:

Yes or you can you 1JZ brackets, the mounts are your choice, stock rubber or MKIV mounts and grind the tip off the top.
so what happened with the link i am going 2j and need some info on the wiring even though i will be not doing it
You have to find it, here is a direct link http://www.supras.nl/index.php?option=com_content&task=view&id=34&Itemid=50dubsupra209;1745583 said:
Fixing to start wiring my aristo harness to my 87 supra. Just a couple of questions.
1. Guys that put a hole in their fire wall on the drivers side. Do I need too extend the aristo harness to mount ecu in stock location?.
2. If yes to one how much longer?
3. On the big grey body plug on the aristo harness, I just cut it off and run the proper wires to the supra body plugs?
4. If yes to three how much more wire would I need to reach the supra body plugs?
5. The e10 section on the ecu would be completely unused?

It works for me, though google chrome gives me a warning that the site may be infected with malware, but when you go to the diagnostics page it states that malware has not been detected on the site in the last 90 days. So proceed at your own risk.

3. Yes, I took the time to fully delete the unnecessary wires from the harness as well.
4. I added 16inches and it turned out about right for me. I've heard different from other people.
5. No, there are still a few used wires on that connector.
