MSD 6AL wiring question

[Forces]

MSD 6AL with an HEI dist, MSD in cap coil. I've got everything wired up correctly except the 16 gauge red wire. It is supposed tie into two sources: key only (ignition) and it needs power while cranking.

The KOEO part is taken care of. How to I wire it into 'power while cranking'? I have a ford starter relay, but I am worried that if I tie it into the "S" or "P" terminal on the relay that when the engine is running, not cranking, the starter will keep trying to crank the engine.

Just run the old coil wire to the MSD, and the MSD output to the Distributor.

Well, after screwing around chekcing some things I found the the Black/White ignition wire, that origonaly went to the HEI "BAT" terminal is power in key only and Power while cranking. I have run into another issue though. I was cranking it over to see if I had spark, and through the windshield I saw a bit of smoke coming from the rear of the engine bay.....Just fried a $70 coil. What gives? I hooked all the wiring up exactly the way the instructions say to.

I did the same thing on an old mustang i had. Did you remember to hook in a ballast resistor?

OK lets see if I remember how to do this, heavy red and black go to the battery, orange and black go to the dist, white isn't used, you need an MSD wire to go from the dist to the magnetic pickup, and red goes to a switched 12v source normally the key. Are absolutely sure you have the orange and black hooked up correctly? They should go black to C- and orange to B+. They are very easy to screw up and I have done it several times. That should do it these things are really easy to use once you get the hang of it.
