    engine harness grounds the ECU. Sometimes people add a ground from the ECU case to ground just to be safe. My ECU wasn't grounded through the harness so I added one.

    Engine mount to chassis. Should be passenger side to frame rail.

    Ground at the front of the fuel rail.

    ground from the harness to the passneger side strut tower.
