Mod – Detachable Power

Replacing a mouse hole power cord with a detachable cord

Our Jayco came with the power cord attached inside the trailer and fed out through a hole in the wall. The hole has a cover on it, but they are often called mouse holes for a good reason. One of the first mods done to the trailer was to replace that mouse hole with a detachable cord.

A number of kits are available to do this conversion. It is a fairly simple project that uses only common tools. Be sure the conversion kit matches the ampere rating of the current cord.

  1. Remove the mouse hole cover and extend the cable fully. The majority of this cable is going to become the detachable power cord.
  2. Cut the cable leaving enough still attached to the trailer to work with and connect to the back of the new inlet.
  3. Connect the wires to the inlet and install the inlet in the hole. The kit comes with different adapters to fit pretty much any trailer manufacturer’s configuration.
  4. Attach the plug to the cut end of the loose cable.
  5. Plug the cable into the inlet with a twist. The other end goes to the outlet as it did before. Detach and coil up when not in use.

Yes, you lose the built-in cord storage, but you avoid having a large hole in the side of your trailer. The cord coils up nicely in a 5-gallon pail.
