I have a King wood stove and it has a blower unit with a two position switch. The blower switch unit is made by Martin Industries Model KB 902. There are two on positions and one off position. One of the ON positions turns the blower on directly while the other ON position activates a thermal switch that doesn't turn on the blower until a certain temperature is achieved. I bought it used and the wires were unhooked. I need to know how to wire this back up. Any suggestions will be appreciated. Thanks, Randy
