IN general, these are the colors and functions and the leteer in () is stamped on the switch itself :
Light green = main headlight output to dimmer (H)
Tan = wire to instrument lights (goes via a fuse in the fuse panel) (I)
Yellow = switch grounds this to complete dome light circuit (D)
Pink = fused power (B2)
Black = main power in for headlights (B1)
Black ? = Parking lights (P)
Black ? = Taillights (R) (amy be combined with taillights out of one connection)
