I have a question about the ECU wiring harness.
There are three pairs of white wires with female spade terminals on the harness. I believe they are the ground wires for the fuel injectors, but I can't find where they are supposed to connect. Should these wires be connected to the negative (-) terminal of the ignition coil? If anyone has a photo showing the correct connection, I would really appreciate it. Thank you! |

Mine is further back, right by the flywheel end of the motor. But still up on top. Really, any case bolt should work for a ground.
