This trailer-end connector gives you the functionality of a 7-way, but without any pins or blades to bend or break. It's designed to work with a matching EZ Connector socket (sold separately) to create a secure, watertight connection that lasts. Strong magnets in both the plug and the socket keep the connection tight and secure, even when you're driving on rough terrain. Built-in O-rings create a seal to keep out water and debris. And spring-loaded, face-to-face electrical contacts are long-lasting and easy to clean. These factors combine for a strong, durable connection that's easy to use and to maintain.

Magnetic Plugs Stay Connected

The EZ Connector system uses magnets inside the plug and socket to hold the connectors together. Simply insert this trailer-end plug into the vehicle-end socket (sold separately) and the internal magnets will snap them together, no latch needed. To disconnect, just pull the plug out by hand.

This is an improvement over typical trailer connectors, which rely on a plastic latch on the socket lid to hold the trailer plug in place. With any trailer connector it can be easy to forget to disconnect the wiring when you unhook your trailer. If you drive off without disconnecting a standard 7-way plug, the connector will get pulled out of the socket, likely tearing off the lid. Without a lid, the electrical terminals are exposed to damaging moisture and debris. But if you forget to remove the EZ Connector plug when unhooking your trailer, the plug will disconnect from the receptacle as you drive off. And because there's no latch on the socket's lid to get in the way, the lid will automatically close to cover the terminals.


The magnet inside of this trailer connector is made of neodymium, an extra-strong, rare-earth alloy. This high-quality magnet ensures a tight connection between the connectors that is stable enough to make it through intense bumps and road vibration.

Silicon O-Rings Create Watertight Seal

This trailer plug has 2 silicon O-rings that create a watertight seal when the plug is inserted into the vehicle-end socket (sold separately).

Plug Holder

A storage holder is included to keep the plug safe and dry when it's not in use. This holder conveniently attaches to your trailer so that it is always available when you need it. Simply plug in the connector, and the plug's O-rings will create a watertight seal with the holder, just as they do with the vehicle-end socket. This ensures that the terminals on this trailer-end plug stay protected from moisture and debris at all times.

All of the EZ Connector systems have earned a perfect score on the SAE water submersion test. This means that the seal created on this connector, either with the plug holder or with the EZ Connector vehicle-end socket, will stay watertight, even if the connector is completely submerged in water for extended periods of time.

No Pins or Blades to Bend or Break


This EZ Connector plug has spring-loaded, face-to-face electrical contacts instead of pins or blades. Pins and blades can bend, corrode, and even break off, which can lead to a permanently damaged connection. With the EZ Connector system, there are no pins or blades to bend or break. Because there are no pins or blades, there are also no pin sockets on this connector that can trap debris. And if any dirt or debris does collect on the terminals of either end of an EZ Connector setup, it can be quickly and easily wiped away. No more scraping pins to get grime off. The result of all of this is a quality, effective connection every time you plug in.

Video Transcript for EZ Connector Magnetic 7-Way Trailer Connector Review

Speaker 1: Today we're going to be taking a look at the EZ Connector Magnetic 7-Way Trailer Connectors. They are available in three sizes. These magnetic trailer connectors take the hassle out of loose connections, bent or broken terminals, and rust or corrosion. The built in magnet makes for a secure seal and the O rings make for a watertight seal. Also included is a magnetic plug holder that you can attach anywhere on your trailer. It's great for keeping your trailer end up and out of the way when not connected.

The notches ensure that you will always connect it properly. The magnets are powerful enough to stay connected despite the bumps and vibrations common with towing. The magnetic connection easily separates. This can prevent any accidental problems should you forget to disconnect the wiring from your vehicle.Now that we've gone over the features, I'll go ahead and show you how to get it installed. Now the easy connector does come pre-stripped of its jacket revealing the wires.

Now I've already gone ahead and connected some ring terminals to help us out with our installation because we're going to be using a junction box. And you can pick up some ring terminals with part number 44-5310A. I've staggered the length of my wires according to the position in my junction box. This is also going to give it a cleaner look and make it easier to install.Let's install this last ring terminal together. What we want to do is trim back about a quarter of an inch.

Clean up our wiring a little bit. We'll take the ring terminal and put it in place. Now we want to make sure that we can get the wire up to the very end of the terminal. That way we can crimp it properly. Once I've got it where we want it, we can then take our crimpers and crimp it down into place.

Great.Now let's go underneath our trailer. I've already gone ahead and removed the cover off of my junction box. Here you can see my trailer light wiring. Let's go ahead and connect our 7-way wiring. Now there was a grommet on my junction box, that way it keeps out water and moisture, I went ahead and put that on first. Now let's connect our wires. So I'll take my white one first. And I'm going connect it to my ground. For my remaining wires, I've connected red to left turn, blue to brake, green to taillights, yellow to back up, brown to right turn, and finally my black to my power, which is my battery. As an alternative to connecting it to your junction box, the kit comes with some butt connectors and heat shrink tubing.With everything connected, let's test it out. Here's our left signal, our right signal, warning lights, and brakes. And that's going to complete our look at the EZ Connector Magnetic 7-Way Trailer Connectors.

Best way to get lights on a trailer. Only connections I will use now. I have them on both my trucks and every trailer I buy

- 319-S7-10

Install wasn't too difficult. My trailer had factory connections made with mechanical connectors. I disconnected all of the splices, pulled the pigtail out, pulled the interior wires out, soldered the EZConnector wires to the trailer wires outside of the trailer, applied the heat-shrink tubing, and pushed the wire bundle back into the trailer compartment at the same point they were previously. Worked perfectly with no additional work.

  • Recommended Magnetic EZ Trailer Connector for Trunk and Gooseneck Trailer
    We've got exactly what you need. For the bed of your truck, you can install an EZ Connector using part # 319-S7-09 which would plug inline with the connection at the back of the 7-way on your rear bumper (assuming that the tow package harness on your vehicle plugs directly into the rear of the existing 7-way) the harness is 7-feet long, so it'll work great for you. On the trailer end, you'd use part # 319-S7-10. You can see some product videos featuring these products by using the provided...

  • EZ Connector Magnetic 7-Way Vehicle and Trailer Wiring For a 2013 Toyota Tacoma With Factory 7-Way
    The EZ Connector Magnetic 7-Way Trailer Connectors # 319-R7-02 includes both a trailer 7-way and a plug and play harness for your 2013 Toyota Tacoma. This system will not replace your factory 7-way but instead will create a additional connector. You really don't want to replace your factory 7-way as then it will limit what trailers you can tow. As the harness is plug and play you simply remove the factory connector going into your 7-way connector and insert the new harness in line. You...

  • Parts Needed to Add EZ Connector Style 7-Way to 2012 F350
    Everything you mentioned would work well. The EZ Connection part # 319-S7-06 will work great on your truck and will mount with the part # 319-S7-61 and the # 319-S7-10 is the correct kit for the trailer side. The Y-adapter you sent in a picture of is perfectly compatible and would be what you'd need to add this type of connection to your truck while still allowing your standard 7-way to function. We don't have anything similar though so that adapter would be your best option.

  • Upgrading Trailer 7-Way Connector To an EZ Connect Wiring Harness
    If you are going to change connectors the EZ Connector Magnetic 7-Way Trailer Connector # 319-S7-10 would be the route I recommend going. Unlike your 7-way blade and 7-way round connectors this connector does not have any form of tension connector that can wear out over time. The connection pins sit against each other with no connector sitting around the pin that may become loose. For the vehicle side there are a few options but the most common being the EZ Connector Custom Vehicle Wiring...
