bypassing ballast with stock ignition module

If the 5th pin is live you MUST use the dual ballast Look at the top diagram (5 pin) I posted. Look at the far left wire labeled "new wire" It is labeled that way because "they" were wiring this up from scratch I guess. A harness would already have that. In the diagram it goes to the left side of the ballast. Notice the "U" in the ceramic block on one end. This is so you can tell the two apart, the section on the right side on that page IS BASICALLY THE SAME as the old points ballast and wiring "does not change" for that section.

IN FACT let's say you have a working 5 or 4 pin Mopar ECU setup, and it quits. "You" just happen to have a points distributor in the trunk. You can grab it, unplug the box and the electronic distributor, slam the points dist. in there and hook the wire back up to coil NEG and it will run fine, and be wired right for ballast and the bypass circuit.
