    Default **How to wire a soarer 1JZ into MA70**

    UPDATED: Added pictures of the plugs.

    First off, I'd like to say that Odomd did all the figuring out of the wiring. With his permission, I'm posting the instructions for those that happen to get a soarer 1jz and want to put into a MA70. I used the instructions and mine runs now with no problems. Use these instructions at your own discrection. Myself or Odomd aren't to be held responsible if you wire it up wrong.

    **Note** This is the wiring for a 1987. I used the same instructions for my 1990 and almost all the wires are the same color. Only a few were different on mine were a little different, but easy to pick the right one anyway. Also, the PPS wiring, some of the AC wiring, and cruise wiring, and the reverse lights if using a manual aren't complete yet. I will edit when that gets done.

    **Note** If you get the soarer 1jz, you WILL need to get the supra 1jz mount bracket if you are dropping it into an 89+. If you have the pre-89 crossmember, you will need to use the BIC mounts. Also, the soarer rubber mounts won't drop right in either. You will have to get the 89+ supra mounts or shave off the dimple on the bottom of the mount.

    How to wire a 1JZGTE from JZZ30 into MA70

    There are two plugs on Driver side near Junction Block #2, a 3 wire plug and 7 wire plug

    3 wire plug EB2

    • Black – yellow from old alternator plug and black from EB1
    • White – white from old alternator plug
    • Black/Red – Black/Red from C1 plug and Black/Red from EB1

    7 wire plug EB1

    • Blue –Blue from old AC connector
    • White – White of C1 plug
    • Black/Red – Black/Red of C1 plug and Black/Red of EB2
    • Black – Black of EB2 and Yellow of old alt plug
    • Black/Orange – Black/Orange of C1 plug
    • Black/Yellow – Black/Yellow of C1 plug


    Next you are going to be using wires from engine harness are IJ1, IJ2, IK1, IK2
    7M plugs that you are going to use from inside the glove box are M1, B1, B2

    EB1 and EB2 plugs






    IK1


    IK2


    IJ1


    IJ2


    The EB1 and EB2 plugs are usually cut off and are in the general area highlighted below.


    Wiring the M1 plug is mainly for your gauges
    • Brown – Brown from IK2 (ground for cluster)
    • Yellow/Black – Yellow/Black from IK1 (Oil pressure gauge)
    • Grey/Green – Blue/Yellow of IK1 and Yellow/Green from IJ1 (Engine Light)
    • Purple – Black/Yellow from IJ2 (12v switch, alt to charge batt)
    • Red/Black – Red/Black from IK1 (Reverse lights)
    • Yellow – Yellow from IJ2 and Red/Blue IJ1 (Speed sensor)
    • Yellow/Green – Yellow/Green from IK1 (Water Temp Gauge)
    • Pink – Pink from IJ2 (Speed)
    • Black – Black from IK1 (Tach)

    Wiring the B1 plug is mainly for ignition and fuel
    • Green – Brown from IK2 (Ground for Fuel Pump)
    • Black/Blue – Black from IK2 (NSW)
    • White – Blue from IK1 (AT Switch)
    • Black/Red small – Green from IJ1 (Fuel)
    • Black/Orange small – Black/Orange from IJ2 (switched power, ignition)
    • Black/White big – Small Black/White from IJ1 (Starter)
    • Black/Yellow – Black/Yellow from plug on engine harness loom (VSV Water)
    • Yellow – Red/Green from IJ1 (Fuel)
    • Red/Yellow – Red/Yellow from IJ1 (ELS)
    • Black/Orange big – both Black/Orange from IJ1 (Switched power, ignition)
    • Black/Red big – Black/Red from IJ1 (Fuel Main)

    Wiring the B2 plug
    • Blue – White from IK1
    • Green – Green from IK2
    • Yellow/Blue Red IJ2

    No check engine light here. I believe the green wire from the B1 plug to the brown wire from IK2 grounds the signal so there isn't a check engine light.

    I got the auto one since I already had the r154 and of course a lot cheaper. Just had to of course get the 1jz bellhousing, 1jz lightened flywheel, and r154 clutch. The auto wiring harness has 4 of 5 extra plugs that I chop off.

    this isnt stickied yet?? BTW, (not to hijack) but af, who did you go through and what did it run you.

    There's something about cruising the streets in a highly modified 20+ year old Japanese car, and absolutely raping the newer domestics/imports that I just couldn't replace with a newer car... - shaeff

    Yea, I thought it would be stickied by now.

    I got the engine from Osaka Motors. The engine was is pretty good shape when it arrived. Only problem was one of the ECU plugs was crushed. But, Odom had a spare for me. I think that it was around $1000 shipped for engine/tranny/ecu and everything else. Even had the ignitor and map sensor.
