On my MSD 6AL ignition if i didn't have the white wire hooked up would it still run? cuz mine does and a guy said i'll be fine cuz its only for the rev limiter. white = to points amplifier. also can the car start up without the external coil on it? mine did and i just wanna see if its working or not, but when i took off the wire on top of my MSD Blaster 2 coil it was shocking the hell outta me and i'm like OMFG. lol.. that was a blast, any way i just wanna know if it is actually working or not. thanks
