I have come upon the final stages of my project and need advice on the installation of my MSD6al ignition box, I have the stock 67 wiring harnesses throughout. I am also using a dual field alternator, MSD probillet distributor, blaster coil, a voltage regulator and wish to use the stock ignition switch. I dont want to hack up the wiring on this car, any help or tips on this installation would be graetly appreciated. Where should I get my switched power for gauges or what color is it for my lights and such?
