it should work with the stock ecu if you follow the diagram.
but:
the brown wire splits for the 2 & 3 trigger; brown/yellow splits for the 1 & 4 trigger
black is a shared ground
blue is the 12v source
yellow/blue is the tach output, you need to attach the black/white to this lead for a 1v source to power the signal.
that's it.

it's that way all the way to 2005...dunno why after the first 3 years they'd swap it. I used the same.
when i was building the MSs I was reversing the output inside the CPU itself, so on the harness it will look different.

Again, that was from MEMORY. I wasn't looking at his car when I wrote that, as I'm not looking at it now. I just thought I remembered the yellow stripe coil was the dead one.
Not all of us can be cool like you with 4 triggers.

Well, I checked grounds and wire harness three times last night and it was perfect. Stupid me finally decided to check the coils and the number 3 coil wasn't firing. So just to check the harness and coil I swapped it with the number 1 and it still wasn't firing. I guess I got a bad coil and will have to go searching again. Thanks for all your help guys.
