alternator connector re-wiring

I see no reason you won't still have the CPU 'cause it is tied to the turn signals etc and it's not part of the EM harness on the engine. So if you keep that CPU that means the alternaor relay is still active inside the CPU and all you have to do is run a wire/splice a wire to the white/black wire at the CPU plug to the alternators small connector to have normal alternator excitation.

With a haltech etc your losing the EM harness that the white/black normally runs thru on a NON TURBO car and that's why you'd run a new spliced wire from the CPU's white/black to the alternators small plug. IF the car is a TURBO car the white/black does NOT run thru the EM harness on the engine but thru the harness on the left side of the engine (that's the engine harness) . That's shown in the first jpg I attached.
