to me, the instructions show to bypass the ballast for the 12v to turn it on, but what goes to the coil +? i left the stock setup as is and just ran the red wire to the 12v ignition switch side of the ballast.
The wire that is feeding the coil is going to feed the Distibutor also. One thing to keep in mind is that the blue wire only has power on it in the run positon. You will also have to keep the brown start hot wire on the ballast also. They are having you use the ballast as a juncion block for all of the original wiring.
