i know this thread has come up a sh*tload,but i got some big time issues goin' on that noone can or will help me with. jzx90 1jz goin' in a 90 ma70. jzx90 harness under the dash is the main issue. NEEEEED ect,trc and abs ecu pinouts PPPLLLEEAASSEE!!!!
thanks a lot for any input, and at least trying.

i will try to help you. need a little more info though. do you have the jzx90 ecu or the jza70? and or you trying to go jzx90 to ma70 harness?

jzx90 with a jzx90 ecu, but the ma70 ect and abs ecu's

can you get me a pic of the ecu (plug side)?

got plenty of pics, the ecu,the plugs i cant figure out, and the colors of the wires that i don't know what they do or where they go.
thanks
grady

The JZX90 ECU pinouts are identical to the JZZ30 1JZ ECU pinouts.

Use the Soarer JZZ30 Pinouts.

I know this because I have a Soarer Engine set in my Cressida, but I am running a JZX90 ECU, so it would fit in the stock location. It's plug and play!

plug and play on the ecu,definitely, that's not the problem. the problem is the body plugs on the harness that are under the dash. i've traced one plug most the wires go straight to the TRC at the trhrottle body. so i'm guessing that is for the TRC ecu. but there is still two more to go.

hey man im still waiting on those diagrams so i can get them translated. let me know if you still want my help.

yeah man, definitely need the help, just been busy as hell.

let me know when you have time.

First you said you couldn't figure out the ecu plugs, now you say that's not the problem?

I'm gonna guess that means you figured out the ECU side?

Not sure what you are needing to translate, but if you have your MA70 chassis/ecu and JZX90/JZZ30 ecu diagrams, that's all you really need!

(Granted you'll be ohming out some wires to trace them, but all the information you need on a wire's function is on the ECU diagram).

i talked to him over the phone he wants the wire colors translated. and i told him the same thing about ohming the wires. but i dont think he really wants to do that

body plugs, ecu is good. three plugs that go under the dash, i know i need some of the wires to run the car, one plug i traced and it runs mainly to the throttle body and traction control plug at the throttle body, only missing 1 wire on that body plug, there are 2 plugs left, guessing trans control, and abs. the 7m trans ecu runs the abs ecu, but the jzx90 engine ecu runs the abs ecu. what i'm looking for is the diagram for the wiring harness, or the trans and abs ecus pinouts, that way i can determine what to bail and what to cut and splice to drive the car.

I need major help. I did not get a front cut. All I got was engine ECU and tranny. I could not tell you what type of car it came out of. All I need to do is find out what wire does what. And lastly I have no clue how to post a pic. if you think you can help please email me and I will send you pics. mr_alaska00@hotmail.com
