What about converting the 99' harness into the 04 harness? I have the 04 harness, and located the harness for the CoP and I found this:
The color wires for spark on 99's
It's in the front of the engine? yeah wtf right?
Black/white,black,brown,brown yellow. Those are the ignition.
They come over top the engine plug right there at the water pump neck, then go between the intake/engine where the injectors are? It's weirddd.
If the power comes to the top that's where I'm splicing I would imagine? I just don't understand why it's going back threw and (I think) down to another bundle of wires.
The only thing is, the 4 plug these plug into comes out as black, black, black/white, black/red. Yeahhhh.
