Hi Bill, thank you for reaching out. The positive terminal is connected to the fuse block and the other to the battery depending upon the appliance, the second accessory terminal is connected to the LED or light bulb, and the third terminal is connected to the ground or negative. We hope this information is useful!

Heater switch.
Looked and performed as the original switch. As it was a bit larger than the original, it did require grinding a bit off the heater housing to make fit.
