Installing a toggle switch into your fog lights' electrical circuit allows you to control them remotely. Flipping the switch to the "on" position completes the electrical circuit and allows power to flow from the battery to the lights, while flipping the switch to the "off" position breaks the circuit stopping the flow of electricity. Always remember to disconnect the positive battery cable from your battery's positive terminal before servicing any electrical circuit on your vehicle. Failure to follow that simple safety step can result in painful electric shock and damage your vehicle's electrical components.

Step 1

Cut the wire connecting your fog lights to their power source using your diagonal pliers.

Step 2

Remove 1/4 inch of insulation from both new ends of the power wire with your diagonal pliers.

Step 3

Connect the wire running to your power source to the "source" terminal of your toggle switch.

Step 4

Connect the wire running to your lights to the "accessory" or "load" terminal of your toggle switch.

Cover all exposed conductors with electrical tape.


  • Never service an electrical system while it's connected to a power source.
