Mod Description:

Tired of stuffing your shore power cord through the little mouse hole on the side of your RV into a compartment that the cord was never designed to easily fit in to? What about when it’s cold out and the cord is stiffer than a wood stick? Modding your RV with a Marinco power inlet receptacle can help you cope with all the stress and aggravation of something seemingly so simple to do.

Mod Difficulty:

Installation is actually easier than coiling up your shore power cord. Marinco makes a nice kit which includes everything necessary for changing over to the receptacle-type power inlet. It contains the receptacle, gaskets, screws, and a 30 or 50 amp female connector, depending on your RV power center rating. When you cut the power cord during installation of the kit, the female connector attaches to the end of the cord, allowing you to keep your cord instead of buying an expensive replacement.

Start off this mod by removing the screws and mouse hole plug housing. Slide the housing down the cord enough so you can make a cut in the cord about 12-18″ from where the cord exits the sidewall. Strip the wires on each end of the cut. Attach the wires from the cord sticking out of the RV in to the color-coded receptacle and tighten the wire retaining screws. Slide the cord and receptacle in to the hole where the mouse hole plug used to be, lining up the screw holes with the original holes in the sidewall. Adapters are provided if the screws don’t line up or the hole is too large. You can use a little silicone between the sidewall and the receptacle or just use the gasket that came with the kit. Tighten the screws and your done!

All that’s left is to attach the color-coded female connector to the power cord and plug in. Be careful not force the connector in to the receptacle. There is 1 L-shaped spade terminal that must line up with the correct female counterpart on the connector. Line them up and push the connector in to the receptacle, giving a slight twist to the right once the connector is fully seated. This locks the connector in place. Twist the threaded ring on the receptacle so it threads on to the receptacle body. This makes sure that if you trip over the cord (we’ve all done it!) it won’t disconnect or damage the receptacle or cord, within reason of course. It also provides a weather-resistant seal in the event of rain.

    My camper came with this type of cord….when I disconnect it I wipe the cord as I roll it up then I place it in the compartment under our bed….

  2. jmt

    I like just pulling it out…not a big deal.

  3. tvman44

    I put one our last 2 trailers, all RV’s should come with this. So much easier and helps keep the little rodents out.

  4. gnarlykaw

    I did this mod last week. the 30A plug on the old cord was alittle melted from a bad post plug, so I went with this mod instead of putting a new plug on the old cord.

    Every RV I’ve ever owned has a 6″ or so square hatch over the storage for the power cord. Not a mouse hole. These conversion kits seem to ignore this very common setup.

    What do you put in place of the hatch?

  6. ModMyRV

    The standard conversion kit does not include the adapter(s) necessary for the setup you have. Marinco does have an adapter however. Check out their site for the various mounting options available:

    My motorhome requires that when using the generator, that the power cord be plugged into a box inside the storage compartment.

    Has anyone made this modification that has my setup?

  8. rklingborg

    I did this after getting tired of going in and out of the camper to unstick the cord from the drawers and other thigs that it managed to get cought up on.

    I did this mod yesterday. Very simple, and will be much easier that stuffing the cord into that 3″ hole, and trying to untangle it while pulling the cord out. I’ll keep the 30′ cord, and will make up a 12′ to 14′ cord to use also.

    I bought the 301elrv inlet and the305crv female plug and the 103elrv weather cover separatly. I don’t have a adapter plate
    to cover the 31/2″ factory hole. Can i get one or do i need to make my own? Byron

    “Every RV I’ve ever owned has a 6″ or so square hatch over the storage for the power cord. Not a mouse hole. These conversion kits seem to ignore this very common setup.”

    I double this. And marincos setup looks much smaller than 6″ by 4″ square hole. Out of luck.

  12. ModMyRV

    Have you considered adapting the Marinco receptacle to the power cord inlet panel? I don’t have one in front of me but I think the Marinco receptacle just might bolt up to the panel without much fabrication.

  13. EMD_Driver

    I bought a new hatch for mine. I couldn’t use the one with the flap for the cord. I then cut a hole in it, that the Marinco plug fit into. I used the square J-Box plate behind the hatch door for strength. I can now open the hatch, with the Marinco plug attached to it. Marinco should make a conversion kit for these hatches.

  14. ShastaGirl

    After making this modification, has anyone utilized the space where the cord used to be stored? How big is that space?

  15. jparker66

    Good thought. If would be difficult to get to this area in my Holiday Rambler TT. My area is not very big.

    I’ve seen these connections on other RV’s. They look nice, and I’ve considered modding my unit. But, I decided against it. I would end up having to find a convenient place inside to stow the cord, and create extra work hooking/unhooking (I can be a bit lazy). In addition, you still have to deal with a stiff cord in cold weather.
    Personally, I enjoy wiping the cord down as I slip it back into its compartment. It goes in without too much trouble if done carefully enough. And I try to avoid really cold weather by moving to another state!

    My new trailer (2010) came with this setup from the factory. My last trailer, a 1975 23′ Terry Taurus (yes, I know 25 years between trailers, I bought it in 81 and basically rebuilt it from the ground up) had the cord pushed into the bottom of a cupboard. The one problem with the old system is, the cord gets hard with age and sticks pulling out or pushing in.

    The new Marinco connector has stood up very well in the marine industry that it was designed for. It will stand up to the currents that we put through it. The only drawback is the securing ring does break with use and age. They are replaceable though. Stowing the cord is easy enough in one of the outside compartments or a bumper trunk.

    I did this mod with the new Furrion 30 amp inlet. None of the ones I saw would cover the original hatch so I cut a piece of plate aluminum and cut the new hole into that, and mounted the (painted) aluminum plate to cover the original hatch. Love the LED telltale on the cover. Usefull
