running 12v to msd distributor

I just bought a streetfire dizzy. There is a connection labeled Batt. The instructions say I need to run 12V through at least a 14 gauge wire. Where would be the best place to pull power from? The white/pink wires from the old coil are 20gauge (so I read), so that option is out.

Would have to replace the pink wire all the way back to the Ign switch as that is where the supply comes from for the coil

The factory wires aren't even close 20 gauge. Where did you read that?

I read it in another forum. What connection do I use? There are two connections that clip into the stock coil. Both of them have white and pink wires.

Simple
One of the plugs on a dual connector coil goes to the harness (Ign switch ), the other to the dist.
Use the pink wire from the plug that goes to the harness
If you want your tacho to work use the white from that same plug to the new dist
