Re: C20/cummins 12 valve

Wiring:

Would I need a voltage regulator for a cummins for the swap?
Which wires need to be connected to make this work?
Should I run the grid heater? Don't get cold in Texas.
On the 68 I have the following for the alternator.
Red
White
Blue
Black
On the starter side I have the following.
Purple
Black
Yellow

On the cummins I have the following on the alternator:
Big black
Green
Blue

Don't have anything for the starter or the injection pump/shutoff solenoid.
