2 wire alternator

Ok on my cuda someone really 'riged' everything, the belt configuration is like anythign my dad has seen, all the wiring is all messed up, i get no spark awwwww and the guy put a 2 wire alternator on my car, it has dual pullys how does this work

i have the orginal /6 wiring setup and one wire going to the alterntor, how do i get power to everything with only one wire hooked up, i tried looking around the house/yard and no luck with a one wire, not even with my dart :sad9: can someone show me a setup of how a belt setup should be on my cuda 318 ps and fan thats it, right now it has 3 pullys on the crank, then the front most one runs the fan/ps, and the middle runs the alternator...its so riged. Do i have to run a one wire, id like to, can i adapt it to 2 wire.

mainly i wanna get the bet setup right, right altertor, and for the car to fire.

i need a belt diagram
electronic ign diagram
and an explanation on how a 2 wire alt works on my one wire car

thanks i'm really stuck here
