I need the pinouts. I've searched and searched but I can't find what I need. Does someone out there please have this information?

Same as a 94 WRX...
Actually, same as an USDM EJ22T with the exception of the ignition where there are 2 more wires...

OK - I've made some progress with the wiring thanks to the above links. However, there are still some wires that remain a mystery. I have two wires coming off the ecu that are unaccounted for - but I can't remember the pins at the moment.

Also, I have a bunch of wires coming off the engine harness loom that are also unaccounted for. I'm talking about the engine harness connector that has three plugs. One small one and two larger ones - all multi pin rectangular connectors. Does anyone have a diagram that describes ALL the wires coming off the engine?

The wiring doesn't seem to be that bad. Remember that this is a conversion from an impreza 1.8 ecu to the JDM Turbo Legacy. Once the 'ecu harness' is seperated from all Legacy wiring there are only about a half signal dozen connections that need to be made to the impreza wiring as the engine and turbo control wires remain intact. The rest of the wires are power and grounds that I'll do seperatly.

You are likely dealing with the wiring for the AWIC pump...

nope - you can see on the legacy diagram that there is a pin for this. This is the same pin I have already accounted for.

I am just pulling this from memory from my car, but I think what you are dealing with is turn signal and corner light plugs. If you look at the wiring diagram, those cars were wired differently than ours. This threw me a bit of a curveball when I did mine.

IF that isn't it, get us some more detail of where they are on the harness, what color they are, and how many wires, and we'll see what we can come up with...
