I have a 1953 GMC truck converted to 12v and need to wire a Standard HS98 heater switch (photo below). Any help is appreciated.

Connect the wire from your power source to one of the terminals. Connect the wire to your heater motor to the other terminal. It's a rheostat type control so the coil on the back will get very hot when being used.
