I am in the middle of wiring my car and was wondering what size wire to run from the battery to the ignition switch and then out to the ignition? I had read that your not supposed to use to small of wire because of the draw of the ignition at high rpm's, but the article didnt say what size to run. thanks for the info.

Just wired ours this weekend. The MSD ignition has 12 gage wire for the battery and recomends using 10 gage if you're extending the length of the wires. That's what I did. And used 18 gage for the rest of the wire to the dist. ground and ignition switch.

I would not run smaller than #10 wire. That is what is on stock HEI setups.
