TRAILER WIRING - 14FT (168IN) MARKER LAMP JUMPER

Grote 66171 - 14' Marker Light Jumper Harness, Two Standard Males to Two Double Females

Heavy-Duty 14-Foot Power Reach for Trailer Lighting The Grote 66171 Jumper Harness is a professional-grade electrical solution designed for long-run power distribution on heavy-duty trailers. Measuring 14 feet (168 inches) in total length, this jumper provides the necessary reach to power marker and clearance lamps across large trailer frames. It is engineered to provide a secure, "plug-and-play" connection, eliminating the need for manual wire splicing and ensuring the long-term integrity of your vehicle's electrical system.

High-Versatility "Y-Split" Configuration This harness features a specialized hybrid design: Two Standard .180" Male Bullets on one end and Two Double Slim-Line .180" Female Receptacles on the other. This double-female configuration acts as an integrated power splitter, allowing you to easily run multiple lamp leads from a single power source. It is specifically designed for:

• Marker Lamp Systems: Efficiently jumping power between lamp locations.
• Front-to-Upper-Rail Connectivity: Ideal for routing power from a front receptacle to upper clearance lights.
• Modern Lighting Upgrades: Seamlessly adapts standard power sources to low-profile Slim-Line lighting components.

Built for the Rigors of the Road Constructed with premium 14-gauge GPT wire, the 66171 is built to withstand extreme vibration, moisture, and road chemicals. The factory-molded connectors provide a watertight, corrosion-resistant seal that protects the internal copper conductors, reducing maintenance downtime and preventing electrical shorts. This harness is a reliable choice for fleets looking to maintain FMVSS 108 compliance and maximum visibility.
