5. The 2 wires from the harness connector itself (now with the quick connectors) will be wired to the black (-) and orange (+) wires from the MSD unit (as these wires go to the coil - and +).
6. The other 2 wires (that led from the ECU to the harness connector before you cut them) will be connected to the MSD thin red wire (+) and to the (-) wire of the MSD tach adapter. In the picture above, I used a white wire (NOT from the MSD unit) that leads to the (-) of the tach adapter.
