So I've got an MSD 6al box, and an MSD Distributor and coil. The MSD box itself is hooked up and should be just dandy.

My question is how do I wire up my ignition switch/starter/alternator?

I've got the switched signal going to the MSD box, but what connects from the ignition switch to the starter so I can actually crank the motor?

So far as the alternator is concerned, I just need to figure out how it should be wired up to feed back to the battery properly when the vehicle is on.

Hooking up a new ignition system should not affect your starting or charging system, they should remain the same.

Mike, there should be a violet/purple wire that will get connected to the S terminal on the starter. Nothing to do with MSD system as stated. R terminal on solenoid is not used.
Not positive on this without looking at diagram but AI think the alternator feed goes over to the horn relay on your 75 and from there eventually ends up connected to the hot that is connected to the battery terminal on the starter. HTH
