Diode Dynamics Add-On Foglight Wiring Harness

 

Diode Dynamics Add-On Foglight Wiring Harness is a fog light wiring harness kit built for customers adding fog lights to vehicles without factory fog light wiring. It lets compatible fog lights operate automatically with factory-like behavior, using activation and deactivation wiring along with a switch. It gives lighting installs a cleaner connection path while keeping the finished upgrade organized and serviceable.

Configurations support non-backlit Stage Series lighting products, backlit Stage Series lighting products, and connector options for fog lamps, LED pods, and related auxiliary lighting. For customers adding pods, RGBW accents, rock lights, fog lights, or CrossLink hardware, matched wiring support helps reduce guesswork and keeps the installation focused on the lighting upgrade.

High-capacity 16AWG wiring, a waterproof fuse, and compatibility with factory-installed auxiliary switches help make the harness suitable for clean add-on fog light control. The compact layout helps the wiring blend into engine bay, bumper, rack, and underbody installations, while still being straightforward to route near existing harness paths.

The group includes DT 2-pin, DT 4-pin, H11, 9006, and 5202 output connector configurations so customers can select the harness that matches the lights being installed. The Diode Dynamics design gives customers a purpose-built option instead of a loose-wire workaround, which is useful when upgrading existing lighting or adding a new lighting function.

Installation includes connecting activation, deactivation, power, and switching circuits so the fog lights turn on with the desired vehicle signal and turn off when required. Customers should verify connector style, output needs, wire length, and vehicle-side wiring before installation. Careful routing helps protect wiring from heat, abrasion, suspension movement, and steering components.

Whether customers are upgrading for fog light upgrades, auxiliary lighting control, or cleaner factory-like operation, the Diode Dynamics Add-On Foglight Wiring Harness helps complete the installation with a cleaner connection and dependable compatibility. Now Available at LEER!
