Really Need Your Help!! Chaser JZX-90 Wiring Diagram Pinout NEEDED!

Hello,

I'm trying to wire up a 93-95 JZX-90 Chaser 1JZ non VVTI motor. The ECU has 34/22/16/28 pins, and the following part numbers on it 89661-22470 and 175700-7785.

I've tried using the info at 1jz-gte.us, but the file "chaser.pdf" doesn't help at all because its all in Japanese, and the pinouts don't really match up.

Is there anyone out there that can point me in the right direction to find some info on the ECU pinouts, and the general EFI schmatics?

Thanks

Hey Pete. I have it saved on my computer at home. I'm almost 99.99999999999999% certain it is correct. And it is in engrish too.

thanks for the diagram. i had downloaded that same one from 1jz.net. i didn't realize the soarer was the same as the chaser. the problem was a bad igniter, not my wiring or the ecu. swapped out the igniter with a known good one, started right up!

AT soarer and AT chaser (according to the two pinouts that I have) are identical. Soooooo...MT to MT should fit as well.

Pete,
I'm looking for this wiring diagram too - www.1jz.net is in Japanese, so I'm screwed there.

1EVIL-JZX90 - can you send me this diagram? I have an inch thick stack of resources but this isn't in there - thanks in advance

^^^^

yeah thats what i ended up using. i thought maybe they weren't the same, because the car didn't run when i was done wiring it. turns out, the igniter was bad, not the wiring.
