Diode Dynamics Add-on DT 4-Pin Foglight Wiring Harness

Overview
Add fog lights to your vehicle. If you want to add fog lights to your vehicle, but you don’t have factory wiring, this is the solution you need! Unlike other basic harnesses on the market, our Add-On Fog Harness allows your fog lights to operate automatically, just like you’d expect from the factory. By using an activation and deactivation wire, along with a toggle switch, this harness will turn your fog lights on automatically any time the headlights are turned on, and the switch is in the on position. This is much more convenient than manually flipping a switch on every time you want to use them!

This harness is intended to be used with Diode Dynamics Stage Series LED Pods with backlight functionality, and can safely provide up to 10A of power.

Wiring. We recommend connecting the Activation Input Wire to your sidemarker or low beam signal, so your fog lights can automatically turn on with your parking lights or low beams. Any time this activation signal is powered and the fog light switch is in the On state, the fog lights will be turned on.

We recommend connecting the Deactivation Wire to your vehicle’s high beam circuit. This will automatically disable the output any time your high beam is activated.

Finally, we recommend connecting the Backlight Activation Wire to a fused 12V source to trigger the backlight feature, such as the parking light or running light. Before wiring, please check local laws and regulations for proper activation and deactivation of the type of lamp you are powering with this harness.

Auxiliary switch compatible. If your vehicle came with a factory-installed auxiliary switch bank, you can use one of them as your fog light switch, instead of the toggle switch that’s included. Simply connect an Auxiliary Switch output to the harness, using the included Power Input Wire.
