By the time you get all the correct cable together, set up to bundle and then tape or use convoluted tubing you can have Electric Brake Cable
installed with a far better visual result.

Electric Brake Cable is a far quicker and simpler way of installation and you can get on with mounting and installing the controller.
Using this cable will also minimise the possibility of interference due to the incorrect cable size being used.

Many installers are not aware that the red wire has dual functionality, firstly to signal that the brakes have been applied and turn on the controller
when operated by brakes being applied by foot, and secondly carry power to and turn on the brake lights on the trailer to alert vehicles behind
when the trailer brakes are applied manually from the override switch on the dash.
