This trailer set is ideal for use on caravans, trailers or farm machinery. It is wired up to match our inserted plug and socket set if you already have one of those. It will not match our CAB011S medium duty trailer link or the CAB730S types of multi-camera trailer links. The plugs and sockets have 1m tails so you can add the length of cable you need to complete your project. I also means it is easy to change one if it gets damaged in use.
