EFI help needed, Wiring questions.

It is actually fairly simple. The hard part is getting it "neat."

The two white connectors originally connected to the ballast.

1... One of those should have both terminals jumpered together. So the two terminals on one white shell are one big splice. Electrically you need to leave that all connected.

2....The remaining white connector, one wire/ terminal went to the ECU and is no longer used. If you pull that out of there it leads off to the 5 wire ECU connector

The second terminal goes one wire off to the coil + ring terminal, and the second wire is your brown IGN2 bypass circuit. That terminal, those two wires, get jumpered to the first, (1) above and the coil + ring terminal then becomes your switched ignition to key on the EFI and ignition

Then, there is one wire coming from the ECU connector that goes splices into the circuit from (1). So you can snake that one out or tape it off and actually, if you leave some of it "in the harness" you can use it for the wire you need to jumper / splice over to (2)
