Should I disconnect ballast resistor when using MSD ignition?????????????????????

Duster360, don't have to run the ballast. However, if you want to keep it for nostalgic reasons you can disassemble the ballast and solder in a wire to bridge the connection and re-install it. It's how my buddies and I run our units.

How is it nostalgic with a big MSD box on the inner fender? lol
