EFI help needed, Wiring questions.

If my alternator is internally regulated and has a sense wire that goes to a 12v source, (either the starter relay or a distribution block to battery +) wouldn't that eliminate any overcharging caused by harness voltage drop? 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 @67Dart273

For now I will be skipping the relays. Soon, within weeks after getting it running, I will tackle the relays. I will bypass the Amp gauge for now and use a voltage gauge.
