We've specially-developed this trailer wiring package for Range Rover Sport vehicles. This kit seamlessly converts your Rover wiring plug to either a standard 'Flat 4' North American spec plug or 7-way plug (both connectors included!). Our quality harness kits are dependable and cost a fraction of the genuine versions. They feature a rubber plug cap to protect the exterior trailer plug from the elements and easy plug-and-go installation means they can be installed in minutes.

  • 4 ea. M5 x 0.8mm x 40mm machine screws

3. The YWJ500170ABP Wiring Harness comes in 2 parts. One part with the connectors that plug into the Trailer, and the second part with the connectors that plug into the vehicle.

4. Take the part with the trailer connectors and feed the harness through the opening in the bumper (the hole on the left). Maneuver the trailer connector through the opening. It may take some twisting and turning, but it will fit. (See photo # 2A.)
