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! |

I'm pretty sure that #31 should get grounded by the ECU when it sees that the engine is rotating. It does not get a full-time ground.
