try using google..... delco voltage regulator year or years about and make and or model of vehicle and use google images and there u should get a ideas.
couple wires to alternator, another going to be ground, 1 to a idiot light or diode, or gauge which also will break the circuit when shutting down, another to battery or solenoid or a wirng block of somekind, another to ignition or somewhere where it can monitor the voltage used.
figure what alternator or generator you have then look for a basic diagram.
or you can get a basic gm 10 or 12si 1 wire alternator and make it simple
you can get a gm 3 wire and wire it to sense its own voltage which basically will make it a 1 wire
