Im installing pertronix II on a 1970 318. I've spliced the ballast resistor wires together as instructed. The directions say to attach the blue wire I've just spliced to the positive side of the coil, and run the red wire from the pertronix to the positive as well. But, on a 318, there is also a brown wire attached to the positive side of the coil, it runs to IGN 2 in the steering column. Do I put both my spliced blue wire and my IGN 2 brown wire on the + coil?
