Hi all,
New to this forum. I was hoping maybe to get a little help.
I am installing an MSD distributor in my 1973 Challenger. Originally a 318 car, converted to 440 6-pack and about 500hp. Originally had the 318 distributor in, but the increase in HP leads me to believe I will need more spark, so I have purchased the upgrade.
I know I need to run full 12V to the new coil on the Ign. 1 circuit (hot on start and run). The question I have is what color is Ign. 1 wire, and what can I eliminate when doing this install. Through the process of elimination, and as far as I can tell, I can remove the ECM and its wiring, but I find that the voltage regulator and the ballast resistor are tied into some of the circuitry. Can anybody tell me what wire is Ign. 1, and how I go about dealing with the resistor and voltage regulator? I'm afraid that if I just start eliminating things that are "inter-wired" I will lose some functionality or the charging circuitry from the alternator.
Any help here would be greatly appreciated.
