I'm in the middle of wiring a bigport 4AGE up in a oz spec AE86.
The wiring is pretty much all from a JDM AE86 but the ECU is from a smallport oz spec AE82.
What we have working so far:
Alternator
Starter motor
Ignition (get a nice beefy spark when turned over!)
Fuel pump
Having a few problems wiring up the injectors.
I'm thinking that this yellow wire in this picture (the wire in the middle of the plug)
is supposed to be connected to the ignition switch. With it connected to power i get the required voltage at the ECU when i check it and the continuity to the injectors checks out to. The voltage measured at the ECU on the injector wires falls off slowly when the ignition is turned off, seems odd but i don't know if it's good or bad.
This is the ECU side of the plug by the way (JDM end).
And this is the oz side of the plug
Anyways thats as far as i've managed to get. I guess my next course of action is to check the wires from the crank angle sensor to the ECU (2 wires).
Also i would really like to know what the top wire in these photos is (black and orange wire), it's present on the JDM loom but not on the oz spec loom, do i need it for somthing?
Also this is the location of the plug in the engine bay by the way, at the back there.
JDM side to the right of the photo, oz side to the left.
Also one final thing, the ECU plug is OEM on two of the plugs however the plug that connects to interior things like the dash etc has been left off, only the constant power, and the two main relays have been connected on it, am i missing anything there?
There are a few pins which i'm unsure as to what they do.
They are:
Variable resistor (possibly for the fuel pump? i've wired the fuel pump up separately from the OEM setup.
Fail safe relay.
Circuit opening relay
Warning lamp (check engine light?)
Thanks

ae82 small port ecu? or do u mean ae82 redtop 4age cos they use the same ecu, i think the smallport has the grey plugs.
also the camry (sv21, 3sfe) have the same ecu plugs
