Pay attention what you are doing connecting the ballast. It is two resistors in one assembly. Notice there is a "U" shaped index at one end. Here is a simplified diagram

Notice that the two connectors that are jumpered together go to the oblong hole index end. ALSO notice that there is an "U" index hole at the other end. The original factory harness connector indexed into this "U" to make sure it was connected properly. Notice the side that goes to the COIL This must be so. You can not reverse the connections on that end, as the ballast is two different resistances.

Here is where I'm at. Had to go get some more connectors to finish it up. The spliced end goes to the alternator correct?

Also, how many of these little tin caps are necessary between the plug and the ignition control module? There are several in my case. Maybe left over from frying/replacing older ignition boxes?

And exposing the wires (i.e. cutting off the factory tape around them) really helped in this endeavor a great deal.
