Gone.........

 

Haye to ask a dumb question, but what is it. Are you talking about an electric brake control for a trailor?

A trailer shop or RV store should have some detailed info on it. I've never installed one.

 

I can send you the answer in the morning (when it's light outside).One question though... do you have the Land Rover tow wiring harness or your own? If you tell me that I can send you a more detailed answer.

 

The wiring harness on your brake controller should have 4 wires, black, white, red, and blue.

The black wire needs to run to the positive terminal on your battery - making sure to put a fuze in the wire (20 or 30 amp).

The white wire needs to go to vehicle ground. You should be able to find different ground screws on on your vehicle.

The red wire is what tells the brake controller that that the towing vehicle brakes are on. You need to splice this wire into the cold side of the stoplight switch. To get to this you will need to take the panel off right above the brake pedal. As you press the brake pedal down you should see it releasing a plunger type switch above the brake pedal. This switch will have three wires running into it. The wire you are looking for should be green and purple. You will need to splice the red wire on the brake controller intothe green and purple wire on the brake light switch.If in doubt, take a volt meter and get a reading. When the brake pedal is off you should get no reading, and when the brake pedal is on, you should get a reading of about 12 volts.

The blue wire on the brake controller is what actually fires the trailer brakes. You will need to run this back to your trailer connector. If you have a trailer connector that was NOT made SPECIFICALLY for the land rover than you will attach the blue wire on the brake controller to the blue wire on the trailer connector. On the other hand, if you have the Land Rover tow wiring harness installed than you will need to connect the blue wire on the brake controller to the RED wire on the land rover supplied wiring harness (In england the blue wire on the tow harness os for fog lights i believe).

Hope this helps. Let me know if you have any problems.

 

I installed one on my wife's 03 disco. Took a couple of hours, and was relatively easy. I spliced into the factory harness and now her disco can use either 4 or 7 pin trailer harnesses

 

i have 4 wires on my stoplight switch two of which are showing to be cold a grenn wire and a white and grey wire but im pretty sure the white one is ground am i correct?

 

If you are referring to the brake light switch under the dash, see attached. But your colors don't match this switch. Year and make of truck, and are we looking for the same thing?

 

im trying to hook up a electric brake controller and when i test the wires with a light tester i have 2 wires that are activating when the brake pedal is depressed a white and grey and a green they are the 2 outside wires on the wiring harness i have 4 wires on mine and sorry i have a 1997 land rover discovery se

 

Here's the wiring https://landroverforums.com/forum/di...29/#post179231 (I'm pretty sure it's the same on a '97)
If you're hooking up electric brakes you need more conductors than are on a 4 wire trailer connector, at least 6 as you need one for the electric brakes and one for the breakaway switch battery.
