I've been googling. Looks like the terminals are marked TACH and BATT. All I have to do is run a hefty (10 ga) wire with battery voltage to the BATT terminal, put the distributor in with the rotor pointing to #1 when it is TDC, get HEI wires, gap the plugs at .045, and I'm in business.
Just make sure it is a key on switched hot. And on in the start position. If it is hot all the time, your engine will run on and on and on and.........
