Baja Designs RTL Wiring Harness

 

Baja Designs RTL Wiring Harness provides the electrical path needed to operate compatible RTL rear light bar functions on automotive and UTV applications. Separate versions address the routing and control needs of full-size vehicles and powersports platforms. Both are designed to bring the rear lighting system into an organized harness instead of relying on a collection of loose extensions and splices.

The RTL platform combines rear-facing running, brake, and cargo or reverse illumination functions. A dedicated harness helps carry those signals to the rear mounting location while providing a relay-based electrical arrangement for the light bar. This supports clearer rear visibility during trail driving, racing, work, loading, and low-light maneuvering.

The automotive harness is long enough to route toward the rear of a car, truck, or SUV and is intended for the standard RTL. It supports running light, brake, and cargo or reverse functions while keeping the main wiring protected in sheathing. Customers using the turn-signal-equipped RTL-S need the corresponding RTL-S turn signal harness rather than relying on the standard RTL lead alone.

The UTV harness is designed for the longer routing paths found on two-seat and four-seat powersports vehicles. It includes an on/off switch and relay-based connections for the RTL's primary functions. The switch and lead length help customers place the light at the rear while retaining convenient control from the cockpit.

Harness selection should follow the vehicle type and the exact rear light bar model. The standard RTL and RTL-S use different turn-signal requirements, and the final installation may need integration with brake, running, reverse, or accessory circuits. Protected routing along the frame or body helps keep the harness away from suspension travel, heat, cargo, and trail debris.

Whether customers are improving rear visibility for trail use, racing, work, or nighttime maneuvering, the Baja Designs RTL Wiring Harness delivers organized power and signal routing for a compatible rear light bar. Now Available at LEER!

• Separate automotive and UTV versions address different routing lengths and control needs
• Relay-based wiring supports the RTL multifunction lighting layout
• Protected sheathing helps the harness withstand exposed vehicle routing
• One planned harness is easier to service than several independent wire runs
• The UTV version includes a switch for convenient cockpit control

Installation Notes

• Select the automotive or UTV harness according to the vehicle type and routing distance.
• Confirm the rear light is a standard RTL; RTL-S turn-signal operation requires the matching RTL-S harness arrangement.
• Identify the running, brake, and cargo or reverse circuits before making final connections.
• Protect the harness from exhaust heat, drivetrain movement, suspension travel, sharp edges, and cargo contact.

Buyer is responsible for use in accordance with applicable vehicle, road, off-road, towing, racing, and local laws.
