I have been embarrassed over having to ask this question for the last couple of days. I haven't fooled with installing an engine for years, and I have a terrible memory. Now I'm over the embarrassment, so here it is. I built an engine for a guy the other day, and he reinstalled it in his 72 chevy pick up. The wiring on this truck is kinda weird, but he could crank it with the old motor. So here is what i got, the battery is hot(horn blows). I have hot wire to starter, negative to frame. He had 4 wires hangin down for the starter, don't know what all of them are, but he said they were all used when he took the engine out. Doesn't one wire go from starter to Distibutor, one to ingnition switch, and that should be it. If it's hard to understand what I'm talking about, can someone tell me from scratch. Start from battery, starter, disributor, and ignition switch being in, with no wiring, and go from there.

The battery should have a main power wire going to the starter solenoid. Any other accessories that need constant power should be attached to the same post as the constant battery power. The wire from the ignition switch should go to the "I" post on the solenoid. If the distributor has a wire going from the solenoid it is either coming from the same one as the battery is going to, or another small post constant power terminal. The Other main terminal and the "I" terminal will only have power in the cranking position and as such, everything attached to those looses power when you are not cranking the engine.
Other than that, the coil needs power and should have ground wires running into the distributor.
Hopefully that helped? maybe it didn't lol.
Good luck.
