The heater switch was out when I got the truck, there are 3 wires coming from the heater, a yellow and 2 orange.Could someone give me some info on how to hook these up? The truck is converted to 12 volt.

Some replacement motors have two wires to handle positive or negative ground. Take a trickle charger and test it to see what each wire is for. Maybe there is an extra winding to create two speeds. | | |
