wiring diagram who needs

Thanks for posting this info. I'm planning a BHW swap project later this year.

Runninwild, Your spreadsheet inadvertently has an extra row inserted at Pin-47, resulting in 95 pins. I've been digging through wiring diagrams also and match your list once you back those after Pin-46 down a digit.

thanks I edited it. For anyone wondering the ecu output signals to the fuel pump, rad fans and other accessories are switching ground not 12v
