Wiring Land Rover for trailer towing
 
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.

Credit goes to Dan @Tekonsha and etrailer.com

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?
