Trailer Wiring Kit for Range Rover Sport

Applies To:

Item: YWJ500170ABP
Fits: Range Rover Sport | '06 - '09
Range Rover Sport Supercharged | '06 - '09

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.

Parts included in Kit #YWJ500170ABP:
  • 4 ea. M5 x 0.8mm x 40mm machine screws
  • 1 ea. YMZ500770ABP harness with trailer connectors
  • 1 ea. YMZ500393ABP harness with vehicle connectors
  • 5 cable ties
  • Instructions
Tools Needed for Kit #YWJ500170ABP:
  • Phillips Head Screwdriver
  • 10 mm wrench
  • Allen Wrench

Note: You will be working in an area that is near the muffler, so make sure the muffler has completely cooled before starting this project.

Installation Procedure:

1. Remove the left tail light assembly by removing the 2 screws. The tail light will pull off. See photo #1. Disconnect the tail light assembly at the connector and set aside.

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.)
