toyotanick

hey guys, i have recently gotten a caddy alternator that i am trying to put on my truck and the only thing holding me back is the stock plug wires for the stock alternator. i know exactly what i must do with the new alternator but i need to know what each color of the 3 wires that are there do. the truck is a 1994 toyota extended cab 4x4 pickup not wuite sr5 but definatelly not dlx.
