I'm in the middle of trying to extend my wiring harness, as its a JDM harness, and it doesnt reach my USDM car. That being the least of my worries, is somewhat easily addressed. Just extend the wires. Now that the wires are extended to the sufficiant length. I came up with a new problem. What isnt required for the motor to run. I mean, I'm doing a Non-Sequiential setup, and whatnot.

The biggest problem I'm having is.... My car is an 89 gtu. I've got 5 wires left over after extending them, the ones that go to the ECU. I'm posting this in hopes of having someone direct me to somewhere that I can get the information about where these wires to in the harness. I know where they go in the ECU plug.

I would also like to know what I can delete. I've got a white plug, a blue plug and two yellow plugs. I'm aware that the Yellow ones are ECU plugs. I was told by someone that the other two arent required for the engine to run. I'm assuing that there are some sensors attached to them, and I'm going to have to get a few aftermarket gauges and whatnot. But I'm already too far into this to just sell the engine/harness and try to get out while I can.

I'm going to see if I can get it to start with the Stock ECU - Just to hear it run before I get my Power FC and convert to single turbo.

Anyways. The wires that I need to identify are....

Green with yellow stripe
Brown with white stripe
Blue
Blue with black stripe
dull green

For each of these there are two wires that look exactly the same. And I know I cant just wire them up to either of them as one of the Brown with White striped ones goes to the throttle sensor.
