1990 b2200 alternator wiring

anyone know which wires do what for the factory alternator wiring?
the colors i have are
red/white
white/black
(both in same plug)
yellow/green
(plug by itself)

i have searched wiring diagrams in my haynes manual as well as autozone.com and they both have different color wires for my particular year
i need help... if i can figure this out i will have a tech writeup on swapping out the sissy 55amp alternator to a 130amp mustang cobra alternator.

thanks,

jeremy
