I have figured out just about everything with the wiring, but there is one wire I haven't found an answer for. There is a black and yellow wire that goes from the main relay and connects from the front harness to the EFI harness then goes to the injectors. There is also a black and yellow wire that goes to the coils, my question is: does the black and yellow wire that goes to the coils come from the front harness that plugs into the ecu, or does the wire from the main relay connect to the injectors and coils without going through the ecu to the coils? The reason for the question is there is a black and yellow wire from the main relay and one from the front harness plug off the ecu. Any help is much appreciated, thanks.

The B/Y wire comes FROM the Main Relay for the coils and the injectors.

So I just connect the appropriate wires from the front harness to the coils and the black and yellow from the main relay, not from the actual harness off the ECU? I just wanted to be sure because the wiring diagram was a bit unclear in some areas, I know the black and yellow off the harness has it labeled as a Heat hazard sensor, and it didn't seem like that would go to the coils but I don't want to mess this up.
