I bought a procomp dist and coil and need help on the wiring. I understand red wire to + side of coil, I also have a short red wire coming off of main red where might this go? Black goes to -side of coil, I also have a short wire coming off black,where might this go? I have a long wire that goes to 12 volt source. My car is a 65 belvedere, do I bypass resistor or go to ign side with long wire? Also there is an opening on bottom of dist, which I assume is opening to adjustable mech advance,shouldn't there be a cover over this opening?
