Adding a 5-Way Trailer Connector to Hook Up to Boat Trailer

Question:

Where can we find the proper wire for the reverse light so that we can use the 5 pin connector and be able to lock out the breaks when traveling in reverse? Or is there another option that we dont know about? Our boat trailer has breaks and a five pin connector. We have installed the hitch and 4 pin connector but we plan to add the conversion to a 5 pin connector, but not sure where to locate the proper wire. Thanks for your help in advanced!

You're correct that you need a 4-way to 5-way adapter, like part # 47515, to have the proper connection on your 2019 Land Rover Range Rover Sport to your boat trailer. The adapter plugs into the 4-way you've already installed and has the additional wire that needs to be spliced into the Rover's reverse light circuit using the included quick splice connector. I've linked a video of the install on a different vehicle just so you have the basic idea.

The tricky part is finidng the reverse light circuit on your vehicle. The easiest way is usually to remove one of the tail lights and determine which wires behind it go to the reverse light there. Use a circuit tester, like part # PTW2992, to to test the wires to find out which one has power when the Range Rover is in reverse.
