I just removed the Mopar performance electronic ignition system in favor of an MSD E-curve distributor on my 72 318 demon and I've ran in to an issue with finding the proper 12v wire to power the coil. I feel a bit silly in having to ask this question, but what I thought was the proper wire ended up supplying power in the "on" position of the ignition switch and not the "start" position. I hooked up my timing light and the engine sparks once or twice immediately after cranking the engine but does not continue. I ran a lead from the positive terminal of the battery to the positive terminal of the coil just so that I could set the timing and take it for a test drive and it runs like a dream. What wire should I use to power the coil? Should it have power in both the "on" and "start" positions of the ignition? In addition to that, I'd like to know if any of you have a good wiring diagram of the ignition switch and wire paths through the firewall so I can find the proper wire.
Thanks all
