In an attempt to keep a numbers car looking stock under the hood. I solder a 12 ga wire at the rear of the 2 post ballast to provide constant 12 volts. Then I use a pertonix Electronic ign system inside the stock distributor, also to keep stock looking appearance. There are two wires exiting the distributor, but I use a shrink wrap to hide the 2, and make it look more like 1. Here is a pic, although not a great one.
