What color the fuel injection wire is that goes to the ignition coil?

I am not sure I know which wire you are talking about. The fuel injection wire that goes to the coil is not on this wiring diagram.

So I am attaching the entire diagram below for your review.

Also, here are a couple guides that will help with testing the voltage if needed:

Please see the wiring diagram below and let me know the details about what you are trying to find and I can be of more assistance if needed.

Thanks
