Currently swapped a d-series motor to a b-series. Old d-series was 2 barrel carburettor. There are no wires for Injection. Most of the loom to the ecu has been fed to the ecu. I have a main relay and engine wiring. I need help connecting the Yellow/black wire that comes from the injectors, it is supposed to connect to the main relay and other parts. Anybody have a diagram or advise I can follow.
