MAD electrical upgrade for 1973 Dart

Ballast is not required on an MSD 6 box. The wires from original ballast to MSD only turn the box on. You can leave it in series, but, it's not necessary.

The mad deal gets rid of the black charge wire and red power wire from the relay lug bypassing the bulkhead. If you want to run a fuse link, I put it attached to the relay lug and have two wires (alt wire and relay lug) travel into the car attaching to the existing black and red wires inside.
