1jz will not turn off after key turned to off position and removed!

[808steeze]

A little about the setup, it is a motor, tranny, ecu, and harness not a front clip. I basically took a 7mge engine harness hacked it up and spliced it into the 1jz harness. Car starts up and runs great, however will not shut off when key moved to off position. I probably missed a wire but do not know which one. Any help much appreciated.

Thanks.

How did you wire it up?

Sounds like you have a relay wired wrong. Or the power to ecu is constant and not switched

So basically what I did is take that yellow plug by the fuse box and wires up to the ecu and strip them from my 7m harness and hooked it up as follows.

red and black wire: BT(T1)(, B+(T12), and a third wire going to B1 9
yellow and black: Bat(T2)
orange and black: M-REL(T3)

IGSW(T13)ECU goes to B1 16

!!!!!One thing I did do that might be wrong is I wired all my injector power wires into switched power?!!!!!

Let me know what you think. THANKS

The injector wires should have been wired up already. All you had to do was splice into b+ for the red black wire to the c1 connector.

What Ecu are you using?

When I got my 1jz engine harness someone had already lengthened it, however while doing that they ended up pulling all the pins out of my T connector that plugs into the ecu. That is where the splicing of the 7mge harness came into play.

As for the injector wires. I am pretty sure they were injector wires and two other sensors that needed power. A large group of black wires that had been soldered to a grey connector with like three red and black wires coming off of the connector. I cut the connector off and ran these wires to a lead off of switched power. I have no idea what kind of power source these wires need.

I am almost positive my computer is a JZA70 Supra computer!
