I'm working on a 53 3/4 ton that's been converted to 12 volts.
the motor was in the truck when I got it and is 12 volts.
the colors of the wires are red which is the hot.
white, yellow, and green.
the switch has 4 terminals B P H and L.
I figure these to be batt, park, high and low
I don't know which of the yellow, green, and white wires are which.
I guessing the ground is through the mounting to the cab.
any ideas out there?
thanks
