EZ wire ignition switch with MSD (no ballast)
67 Dart273. Thanks so much for this! Installed MSD 8388 ProBillet replacing 5 Point Mopar ignition to get rid of the ballast and ECM. Ended up I had Ignition 2 (brown wire) hooked to my coil initially so was only getting 12v during cranking and as soon as I let go of start the engine would quit because of no spark. Spliced Ignition 1 (blue wire) to the positive port on the coil along with the brown wire and MSD harness and she fired right up! 12v at “on” from the blue wire which shuts off at “start” but brown wire provides the 12v at “start” and shuts off at run. I think what’s confusing is the blue wires from the alternator, voltage regulator, ignition, and coil are all tied in together. I used a four way wire connector. Anyway for anyone swiping from a Mopar 5 pin ignition to an MSD 8388 I hope this helps.
