Video Transcript for Curt Trailer Plug Covers - 4 Flat Cover - C58200 Review

Today we're going to review part number C58200. This is the Curt 4-way Flat Wiring Connector Cover. Now this cover is made to cover your 4-way flat connector. It is made of a flexible rubber. It helps prevent rust and corrosion and prevents any damage to the terminals of your 4-way. This is designed to be used on the vehicle end 4-way and I'm going to show you one of those in a minute here, show you how this works.

This part number would be for a quantity of one. Here's an example. I pulled a 4-way vehicle end and the reason this is a vehicle end 4-way is because if you'll notice three of the terminals have the rubber covering them and the ground terminal is exposed. The reason this cap is designed to use on the vehicle end is because if you look on the inside of it, there's an area for the three terminals that have the rubber around it to clear and then on the very end there's a round circle that fits on that exposed ground. When you go to install this, you'll just go ahead and slide this over the 4-way. Go ahead and pull it all the way down and you could actually just leave it on like that and when you're using this, plug in your trailer and use it like that. When you're done trailering 00:01:11, just unplug it.

Take your cap, just swing it over, put it right over and it closes completely over the terminals. Then that way when you're not using it, that won't be dragging down and damaging the terminals or any elements getting to the terminals. Then just pop it off, just pop it off like that and if you want to remove it, you can just pull it off the 4-way like that. That should do it for the review on part number C58200, the Curt 4-way Flat Wiring Connector Cover. .

Curt 4-Way Flat Wiring Connector Cover - C58200

Average Customer Rating:  4.8 out of 5 stars   (226 Customer Reviews)


This does not seal very well, Its loose not a tight fit. I bought a 4 way to 7 way plug and the 4 way on that had a nice hard plastic tight fit cover plug that came with the assm.


works fine. used quit a bit and lucky to have it.


The Curt 4-Way Flat Wiring Connector Cover is exactly what I was looking to find as a replacement for the lost cover on my trailer wiring connection. The Curt cover is designed to slip easily over the male connector and seal out dust, dirt and water with the snug-fitting cap. The cover is flexible rubber and is well made.


Perfect for protecting my connectors and keeping them clean.


Just what I needed to keep dirt & water out.


Good experience


you guys are great, good prices and quick service, I have been a customer for years !


I’m no stranger to etrailer, a few years back I found you folks and ordered a hitch for my 2009 Hyundai SantaFe the installation was extremely easy. Your installation tutorials from Ryan are spot on. The trailer light assembly installation went just as easy. So it was without hesitation I ordered a trailer hitch and light assembly for my new 2022 Subaru Ascent. Once again a super clear,well explained installation tutorial.You folks are the BEST when it comes to after market trailer hitches.
Also, for some reason the new flat plug light assembly did not have a debris cover. You folks sent me out 2 covers lickity split. Thank you etrailer for being the best,friendliest,professional, aftermarket trailer product company out there!!!!


Shawn B. (& everyone I talked with at E Trailer) was wonderful.
Great phone support. Great products. We did a great job installing the wiring harness.
Made me wonder why we originally took it to a "professional" trailer sales & service place in Ogden UT. They hacked into our wiring & created problems.
I will continue to be a grateful customer.
Finding good people who know their stuff in todays world is a soul healing event.
Thank you E Trailer!



Wonderful still


This was a quick and inexpensive way to install a permanent 3-way plug on my towed vehicle. Allows wiring to be hidden out of the way and the rubber connector cover keeps dirt out of the plug.



Has it been a year already? Still looks like new and the rubber cover has kept the metal connectors clean. Great purchase!


It initially fit okay. It is not a snug as I had hoped. Now after a year I use a velcro tie to keep it on.


The "etrailer" print on the cover is not white but instead black which blends in with the background. Since I already have the trailer hitch receiver that says etrailer, it would've been nice for it all to match.

The white etrailer logo displayed in the pictures is actually a small sticker we use as a sort of watermark for our product photos. The connector cover is produced by Curt MFG and has their logo molded into it.


This was a great find. Car dealership wanted $$$ for their complete assembly when all I needed was the plug cover. Thank you etrailer for stocking this. Prompt shipping too!

Happy S.


The covers come off easily. Ive already replaced two of them.


I gave this five stars because it's probably perfectly fine for what it is intended. However, I accidentally bought the wrong thing. This cover is meant for the vehicle side, and it's probably fine for that, but I had meant to get a cover for the plug on the trailer side like this Nonetheless, this cover still works on the trailer side -- it's just a little loose.

As to etrailer, I've bought several things from them and they always get 5 stars plus.

This is actually universal for the vehicle and trailer side. If you want to try a different 4 pole dust cover maybe part # C58761 would fit a bit better.


the electric plug cover is fine it could be a little longer so when you rap it around the hitch to hold it there it is easier to plug over the plug to cover it.

Richard L.


it is still working very well. We are using it this weekend to pulll our camper and operate the lights.


Does what is supposed to do.


Cover works as it is suppose to, and keeps moisture out of the contacts. Price was right and delivery was quick! Thank you!


I have used etrailer a few times, always the best service & experience, thank you for everything etrailer!


Year later still great.


I needed 2 4-Way Flat Wiring Connector Covers for my Yakima Kayak Trailer wiring harness system. Etrailer seems to have everything. They had Curt harness system covers. Fit perfectly. Very durable, and cheap


Very happy with the product and seller on this purchase.
Good product and good price!

It installed with no problems and now works great for my "Franken-basket" hitch, which combines a Thule swing-away hitch mount with a low-profile metal basket.


Connector covers (2) and cover w/LED tester work as advertised. A little dab of dielectric grease on the connectors PLUS these covers is all you'll need to keep corrosion and bugs out of your trailer connectors. Just plug-up and wire brushing and trying to get a good connection due to corrosion. Can't beat them.


Bought a used Highlander w/ trailer hitch, and noticed the wiring harness connector was starting to corrode. Found this connector cover on-line. It shipped same day I ordered it & was received quickly. It fits like a glove on my 4 connector wiring harness. Great price too.


These are great storm covers for trailer wiring plugs. I put a small amount of electrical grease on the plugs a couple of times a year then apply these covers to prevent corrosion. They work great !!!


Everything I purchased, works and fits perfectly.

  • Recommended 4-Way Connection Between Towed Vehicle and Motorhome
    The only real advantage of the 4 round over the 4 flat trailer connector is the clean look of the connection point and the protection from elements when not in use. For instance the Pollak Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End # PK11410 has a clean finished look on the front of a towed vehicle and will protect the connection from dirt and debris with the spring loaded cover. Many people like the connection between the motorhome using a harness...

  • Recommended 12 Inch Vehicle Side 4-Way With Mount And Cover
    Instead of cutting off your plug and splicing, I recommend using the Hopkins 4-Pole Loop - 12" Long # HM48145 along with some dielectric grease like the Loctite Bulb, Lamp, and Electrical Connection Dielectric Grease - 0.33-Oz Tube # LT37534 to keep water and debris out of your connections. For a mounting bracket, I recommend the Mounting Bracket 4-Pole Flat # 18144 along with the No-Drill Mount Bracket, Short # 18140. For your dust cover, I recommend the Trailer Wiring 4 Pole Flat (Vehicle...

  • Shortest 4-Pole Trailer Connector Wiring Harness Loop
    For a 4-pole trailer connector wiring harness loop that is 12" or 1' long, I recommend using the Hopkins 4-Pole Loop part # HM48145. This is the shortest 4-pole trailer connector wiring harness loop we offer. You can add a cover to the above harness using the Curt 4-Way Flat Wiring Connector Cover part # C58200.

  • Hitch & Wiring for 2017 Toyota Sienna Towing Boat Trailer
    All versions of the 2017 Toyota Sienna have a towing capacity of 3500-lbs so your new vehicle is up to towing your 3000-lb boat and trailer. Do note that all auto makers recommend not towing anything for the first few hundred miles on the car to allow for proper break-in without putting extra stress on the vehicle. Draw-Tite Class III hitch # 75237 is an excellent choice since it offers a 4500-lb capacity, providing a healthy safety margin. For a wiring harness part # 118498 is a fine...

  • What Do I Need to Use Hitch C11109 with my 2004 Chevy Cavalier
    The hitch, # C11109, includes all the mounting hardware you need to install the hitch to your 2004 Chevy Cavalier. In order to tow a trailer, you also need to purchase a drawbar, and the ball itself that sits on the drawbar. The drawbar for this hitch is part # 3592. This bar includes a hitch pin and clip. Your drawbar requires a ball with a shank diameter of 3/4 inch. I have added a page link that will show you all the balls that would fit your drawbar. You need to select the ball diameter...

  • 4-Way Connector to Power Motorcycle Trailer Lights
    To power up the lights on your motorcycle trailer, you would want to use 20 ft. Wishbone 4-Way Trailer Wiring Harness with 30" Ground Wire # A20WB. This harness has all the wiring necessary to empower each of the lighting functions on your motorcycle trailer. I also recommend using wire loom # 459075-1 and ring terminals # 44-5310A to make the installation an easier process, as well as 4-way connector cover # C58200 to protect it from being damaged.

  • How to Replace 4-Way Cover on Tekonsha T-One Wiring
    The cover for the T-One Vehicle Wiring Harness # 118776 is molded to the connector so I doubt it would be covered under warranty just because you'd have to essentially cut it off for it to fail - but you're more than welcome to pursue a warranty claim if you'd like. Since that's such a small part of the wiring harness though I don't think going through the trouble of replacing the whole unit would be worth it and instead I recommend just picking up a replacement cover like what we find...

  • Recommended Trailer Hitch and Wiring for 1965 International Travelall
    Since there is no custom-fit hitch for your 1965 International Travelall, you will want to go with a universal hitch like the Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver # 41990-07. The # C14082 is not confirmed to fit your vehicle. The Draw-Tite hitch has a 2" receiver and fits vehicle frames up to 44". This is a weld-on hitch so we recommend taking it to a certified welder for installation. For wiring you can use the # C58345 which also comes with a mounting bracket. If...

  • Availability of 4-Way Tester and Connector Cover
    We do have 4-way testers that would plug into the car side of trailer wiring with the part # I26. This has lights that will come on when it detects that a circuit is active. We have the dust cover part # C58200 which is a fit for both the trailer and vehicle side 4-ways of a vehicle. This would work well for you. I attached a help article on troubleshooting trailer wiring for you to check out too.

  • How to Prevent Corrosion on a 4-Way Trailer Connector
    For a cover designed to fit over standard 4-way connectors we have the # C58200. Another very helpful idea will be to put dielectic grease on the pins of your 4-way. This will actually be your best way to fight the corrosion. For that you would want the part # 11755. Basically you will need to apply a liberal amount of it all over the pins of the connectors before you put the cover on the 4-way and you will not have to worry about corrosion.
