Magnum Alternator Wiring

This has probably been covered, i have tried searching but not quite getting the info i need. swapping to a magnum from an LA as far as the charging system is concerned can i just hook the existing regulator wires up to the magnum alternator? and if so which one goes where? i know you can buy a kit. but what if you already have a working regulator all wired up. any input or help pointing me in the right direction to where i can find the info would be great thanks!
