MSD problems

Hi Electric Gurus,
I just put an MSD 6AL, MSD distributor, on my 70 Dart. I have an aftermarket internal voltage regulator in my aftermarket Alternator. So I removed the factory under hood wire harness that went into the middle of the firewall bulkhead. I did not need the factory water temp, oil pressure gauge, alternator, ballast resistor, or coil hook-up, or do I. Since doing that I can not get the car to start. The MSD ignition box is putting power out. I am hooked into a constant 12V power up supply. I am getting intermittent spark to the #1 spark plug. The car just turns over, doesn't even try to start. Do I still need to have the wires going into the Factory dash Ammeter with the MSD? Shouldn't the MSD provide everything it needs to run the car, other than the switch at the steering column, and starter relay?

Looking for help, I am at wits end on this one...

It is a 70, I know there are differences in the 70 for column lock-outs, and linkage. Is there any kind of electrical differences in the ignition switch that would be causing me problems.

Thanks for any thoughts and help that can be given.
