MSD HEI distributer question for 62 C10

[dhamilton62]

Is anyone running an HEI MSD distributor setup on their trucks? I have a sbc 350 in mine and the previous owner did some crazy crappy wiring on the whole thing. There are three wires coming from the distributor to the fuse panel ( which is falling apart ) and the three wires are just tucked into the fuse crimps which really scares me. Does anyone know where all three of these wires should be going to on a stock fuse panel? Thanks so much and sorry if this is a dumb question.
