wiring info needed please

[otef546]

I just set my cab back on the frame and I'm starting to put the wiring back in.I'm using a one wire alternator do I need to run a new wire all together or do I use the big red wire that was one of three of the original alternator wires?Also what do I need to do about the wiring to the voltage regulator that I should be able to get rid of, right?I'm also using a HEI and I know I can't use the original wire that provided power for the points due to not providing the voltage that I need so my ? is what is the best way to do this? Would I need to come off fuse box or ignition switch? Thanks in advance my the help.
