Fitech Wiring Issues

There's your issue. You do not have 12V on the white wire, while cranking. The brown and blue come from the IGN switch. Those have to be wired together and the white wire wired into them. Verify there is 12v while cranking on that set of wires.

The brown wire that was coming from the right side of the ballast or are you talking about brown wire that's coming from the steering column?
