What 1jz do I have?

[ma70mkiii]

I have been trying to figure out for a while what car my 1jz came out of. I got all of the wiring diagrams and nothing seems to match up to what I'm doing. Some of the wires coordinate with the diagrams... some do not. I have pics of my ecu and exhaust and front view of the motor. My ma70 B3 connector doesnt have the same wiring as the pdf diagrams I have. Pin 4 and 10 have 2 wires in them and pin 6 and 7 dont have a wire on them. This is goins into a 1989 supra with TEMS and I dont know if my body connectors are the wrong ones. I might need a different donor harness because when I bought the car there was no motor in it. It was all strung out and it had 2 different harness' but the one i used had the gray connectors so I dont know. Let me know what you guys think.

Perhaps you have an early 89 with yellow body connectors? If your diagrams are for late 89 and on, they'd be for the grey body connectors, which are someone different.

I have gray body conncetors but things just arent adding up. Here is what I have.

ecu is definitely from a jza70.

Well the diagrams weren't exactly right for my swap, there's some guessing involved. Do you have pics of the body plugs on the end of your harness?

The only pic I have as of right now is my EA2 connector, but hopefully soon I will be able to upload sum pics of the other connectors. Is there anyone who has a set of ma70 body connectors or even some pics so I can compare to mine to figure stuff out. I started on a couple of my body plugs but stopped b/c the coloring was off and I didnt know even if the colors were off if they still served that same purpose. But I do know most of the unmatched wire colors are on my ma70 plugs. I will post pics.

Ok more pics. I have all the pics of my body connectors, jza70 and ma70. The B3 ma70 connector is different compared to the one in the diagrams. Help plzz. Also some pics of my supras. The white one is the car my 1jz is going into and my blue/black one is my 88 n/a im trying to get rid of.

It's seems to be a soarer.... Looks like mines, I'll have to check mines to confirm though.
