Help! 1JZ Wiring ECU
#16
Update:
I visited 2 JDM Engine importers today with my harness and ECU on hand. Apparently, 1JZ come in 2 flavors.
1. Engine ECU, Engine Harness, Body Harness and Transmission ECU.
2. Engine/Transmission ECU, Engine/Body Harness.
It is unknown if the differences are caused by year or body code but....
The first 1jz set-up obviously has a separated harness (Body and Engine) and ECU (Engine and Tranny) and the second set-up where the Main ECU controls both the Engine and tranny with 1 harness that connects to all.
I was told that the 1st type of motor set is usually imported for 5sp swaps (SC300 or MKIII) since you dont need the complexity of the tranny ECU. And the 2nd set-up is a straight Auto swap.
Unfortunately I have the engine with the separate engine harness and the upgraded ECU. I am debating about changing my wire harness or selling the motor to a SC300 5sp owner and buying the correct set-up.
Thanks for all the help.
