I am putting this out here as a PSA.

Trying to find anyone that could explain how to set up a Land Rover (or any other vehicle) with a 4 pin (yellow, green, brown, white) plug to be able to tow an RV with the standard 7 blade RV connection was impossible.

Here is the best way to set up your Land Rover for towing a trailer that requires trailer brakes.

1) Spend the money and buy the Tekonsha Prodigy RF Brake Controller
Brake Controllers - Tekonsha
2) You will need a 4-pole to 7-way adapter like part # 37185.
3) In addition to the lighting functions provided by the 4-pole, you will
also need to run the black 12-V power wire from the adapter to the
positive battery terminal via a 40 amp circuit breaker part #9510 4) A length of 10 gauge wire would also be needed. The power wire is
needed to supply the power module mounted on the trailer.
5)The white wire with the ring terminal would be grounded to the vehicle
frame.

- The Brake Control Module utilizes the left and right turn/brake signals (yellow & green) to activate the trailer brakes. No blue wire needed
- The system is designed to run off of the black power going to the battery with a recommended 40 amp breaker.
- The black power wire also charges the RV battery while connected.

Just seen two on ebay under land rover emblems and decals in the auto section.

 

I used the Tekonsha P3 and wired my Disco using the instructions included with it. It was pretty easy.
I tried the RV type sockets but found they didn't hold up with off-roading, so converted to a metal one.

 

Thanks for the heads-up.

Do you know if it is a metal decal/plaque or is it a sticker?
