All my searching leads me to a jza70 supra but I am not 100% sure so can anybody confirm this?

if you have to ask, must be from a chaser

Well I admit my knowledge of 1jz swaps is rather limited, I am trying to find the proper wiring diagram but I need confirmation as to what this is from?
What makes you say chaser?

Two row ECU plugs = JZA70

Three row ECU plugs= Chaser/Mark II/ Soarer/ Aristo

Seeing that it only has two usable plugs at the end I would say it's a Chaser/ MarkII

You need a ECU plug from any mid 90's V6 Toyota Car to power up the ECU, since it looms from a body harness patch. Time to hit the junkyard.

Bummer if that's the case^^ Here is a pic of the ecu

So a mid 90's toyota camry should do the trick? V6 only?

Yes 4 plugs if that's what you mean by rows?

2 rows of ECU pins is Supra harness.

Your harness has more than 2 rows and it's missing two ECU plugs; clearly a chaser harness.

Sorry i dont mean to thread jack but im in a similar situation. Im go to attempt to do a little wiring for my friends 1jz swap. Its clearly not a jza70 harness since it has 4 rows of pins. My situation is that the body plugs have been cut. Just wanted to see if you guys have any info on the pinouts for the body plugs or have any suggestions. Id prefer to not have to trace every single cut wire. Thanks in advance.

No worries ^^
I am searching for a jzx90 pinout right now which I found one but it's not in english so the search continues.

Let me know if you find one. Im sure its floating around here somewhere. Ive checked the diy 1jz swap section, but i can only find the ecu pinouts. From there i can wire a few wires to the body plugs, but not all of it.

Get the Sc300 FSM PDF online, that will give you the Body colors and decode.

I also go over the JZX90 Chaser wiring in my own thread as well. Check it out.

Then you use the Soarer/Chaser ECU pinout and wire that pig up!

Score on getting all the plugs!
