fan speed hasnt worked in my jeep for awhile, so i pulled my heater control box out the other day and the connector to the fan speed control is melted. i am going to cut the wires and put pin connectors on each wire and wire them to the switch. only problem is i dont know which wires go to which post. could really use a hand here if anyone knows.

on the speed selector switch there are 5 posts, B, AC, M, H, and L. its obvious what is what i just dont know which wires go where. THANKS!!!!
