need auto 4x4 on the fly pin out

[lurkinheavy]

Hows it going guys . i bought a used 1989 bronco II with automatic on the fly 4x4. i was trying to get the 4x4 working and i pulled the dash switch out of the dash and noticed that it was not plugged into a harness . no make matters worse . i found the plug and wires stuffed deep down in the dash and only one wire is pinned in the plug . i have no idea where the other wires go in the plug and cant find a pin out for that plugs orientation . does anyone on here know what wires go to which pins on the plug and just to clear this up again its the 4x4 toggle switch on the bronco II
