Diode Dynamics DD4185 Stage Series C1R 10-Pin Single-Output Trailer Wiring Harness

The Diode Dynamics DD4185 is a dedicated wiring harness designed to power Diode Dynamics C1R HitchMount LED pods by tapping directly into the 10-pin connector located behind your vehicle's bumper, near the trailer hitch. This plug-and-play connection enables multi-function operation of the C1R LED pods without additional relays or complex wiring: the pods operate as a red accent light with your tail lights, activate as an additional fourth brake light when the brakes are applied, and automatically switch to high-power white backup lighting when the vehicle is shifted into reverse. The harness also includes an optional SafetyStrobe feature that flashes the brake light function three times upon brake application for enhanced rear visibility — and can be easily disabled if preferred. High-capacity 14AWG wiring and a single Deutsch DT output connector ensure a reliable, secure connection rated for operation from -40°F to 185°F and a supply voltage range of 9–16V.
