Automotive RTL Wiring Harness - Universal

The Automotive RTL Wiring Harness is a purpose-built electrical solution for truck and Jeep owners who want a clean, reliable install when adding an RTL rear tail light to their build. Rather than splicing into your existing wiring with makeshift connectors, this harness gives you everything you need to integrate running light, brake, and cargo/reverse light functions through a dedicated relay — no guesswork, no shortcuts.

The harness is sized with enough length to reach the rear of your truck or SUV without pulling or rerouting your entire electrical system, making it a practical choice whether you're mounting an RTL on a roof rack, spare tire carrier, or rear bumper setup. The high-quality sheathing protects the wiring from the kind of abrasion and exposure that comes with serious off-road use.

This harness is the right match for the standard RTL. If your build includes an RTL-S, you'll want to look at the RTL-S specific harness instead, which includes the additional jumpers needed to tap into your turn signals. Getting the correct harness from the start means a cleaner install and proper function from day one.
