Hi all. On a 66 mustang... the red/ green wire going to the coil.... will i be needing that wire any more since i am converting to an msd digital 6 ignition? What is the purpose of that wire?

It is the coil power wire now, and has a resistor section under the dash that is a fat pink wire. MSD suggests bypassing the pink resistor wire. You will be using the RED/GRN wire as the "switched +12v power" feed to the MSD, to act as the ON/OFF switch signal.
