Hi does anybody have a wiring diagram for the ecu as i have a loom im trying to wire up but some one has taken one of the plugs off the ecu and im trying ti wire up a new plug but the colours are a different colour for a 4age with a map sensor of a mr2 my ecu number is 89661 17020

Thanks

bump... all i need is the wiring diagram of the plug with the 14 pins and in what order...

thanks

if you open it up, it should list on the circuit board what each pin does.

yeah i have opened the computer and its doesnt say what pin goes to what colour wire i just need someone with a 85 mr2 with a 4age to tell me ir have a look on the plug with 14 pins to what orger the pins to colour wire they are....

no the AE86, AW11 MR2 and the AE82's all have interchangable ecu's.

Different wire colours?

by **opticalblue** » Fri Feb 17, 2006 4:16 pm

well ive undone the whole loom and see that most of the wires from the 14pin plug run... im guessing for the light on the dash or so and one green one to the main relay and none to the sensors.. so does anybody know what they are...

thanks

That plug only goes to the dash. I cant help as far as what pin goes where, but I put a 4AGE into my carb'd AE82, and left that plug out. You dont need anything connetcted to it to run the engine. I just used the factory dash loom connected to the appropriate sensors on the 4AGE

Ahh, you sure? I think not.

The only ones you really need are the three power supplies, and if you want the fuel pump sw and the warning light.

Ahh yeah, Sorry. Matts right, i ran the fuel pump off ign feed, but the minimum you will need are the three power feeds.
