Brake Controller Recommendation for Land Rover Discovery with 7-Way

Question

Question:

Is the Land Rover Discovery 5s 7 pin trailer connector able to control the electric brakes on a travel trailer or do I need to buy a 3rd party controller? The 7 pin connector has a pin listed for Brakes, but not sure if this is adequate. any information would be greatly appreciated. thanks

7-ways have the brake controller output circuit on them for activating the trailer brakes but if your vehicle does not have one installed it would not be able to control them until you did.

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.

Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.

I attached an FAQ on installing brake controllers for you to check out.
