EFI help needed, Wiring questions.

Kent mosby said

Also, when I jumper the dark blue and Brown together, the ecu , the ballast resistor wires have nowhere to go. So can I get rid of them, the 5 wire connector, the VR connector and the white ballast connectors . None of them go back into the harness..and there is no VR, ecu or ballast resistors? Help. please .

I thought I addressed this, read above again. The dark blue/ brown need indeed tied together and that splice is what feeds your EFI power "trigger." That was the reference to the old coil+ wire which "becomes" that wire lead.

And yes, reread posts above, you can unwrap and remove the ECU wiring and connectors

Essentially the dark blue "run" feeds several things depending on the year

Ignition run circuit feeds coil through ballast, and power to the ECU, and originally dropped power to the ECU through the second half of the ballast

Alternator field (light blue) VR power and sense--goes to the VR connector. (The green from the VR connector goes back to the alternator field, so it's a "dead" wire if not used)

If electric choke is used, feeds that

Some years, it feeds some smog doo dads.
