Everything original under the hood was bypassed. The brown...blue and all wiring to and from the ballast resistor and the voltage regulator. All wires were terminated at the Firewall plug.
The coil is being powered directly by the MSD Box. The constant 12 volts would be supplied from the blue wire (Ignition 1)that is tied into the MSD (Small Red)...
I can tie the brown in with the blue but I wasn't sure if it would hurt anything.
By tying it into the yellow I knew it would only have 12 volts while cranking...(ignition 2)
In reviewing a few diagrams I think it would work either way???
The Ford starter relay has two connections but allows for 1 large wire to run to the starter while having both terminals on the starter crossed with a metal plate. This wire is only hot once energized by the yellow wire attached to the relay.
