One Leg Ballast Resistor or Two

mopardude62,

It looks like your plan will work fine. Your bottom drawing shows single terminals in place of your current dual. If true, you don't have to cut/splice wires. You should be able to release the "57 terminal" female connectors from your dual pin housings using a tiny screwdriver and re-insert them in single pin housings (your old ones, junk yard, or ebay). I wouldn't remove the green/red wire, but just leave it in the harness. It won't be connected at either end.

As a probably unwelcome rant, I wonder why people fool with the old Mopar electronic ignition and pay $$ for new MP parts and $$$ for new harnesses designed for it. A GM HEI ignition is easy to retrofit, gets rid of the ballast, and lets you use a better E-core coil. I put them together for several of my cars for ~$20 in junkyard parts, as have others. As you are finding, new high-dollar stuff is not always "plug and play".
