Features to know about

Trailer wiring can take a beating from moisture, dirt, and corrosion. The EZ Connector Magnetic 5th Wheel/Gooseneck Pigtail Harness with 7-Way Connector seals tight to keep out water and grime. The magnetic connection holds firm and automatically aligns the contacts, so you get a solid, weather-resistant link every time you hook up.

Switching between trailers is easier when your wiring connects quickly and consistently. This harness uses a 7-contact plug-in layout built for 5th wheel and gooseneck towing setups. The connection stays secure even on rough roads, giving you steady power for brakes, lights, and charge lines without having to fight loose pins or misaligned plugs.

Video Transcript for EZ Connector Wiring - Fifth Wheel and Gooseneck Wiring - 319-S7-08 Review

Speaker 1: Today we're taking a look at the EZ Connector Magnetic Fifth Wheel or Gooseneck Pigtail Harness with Seven-Way Connector. This provides a seven-way connector in your truck bed for hooking up your fifth wheel and gooseneck trailer. The connector mounts on the truck bed sidewall, tailgate post, or wheel well. It does require a 2" minimum diameter hole for the installation. This is a pigtail harness that needs to be hard-wired into your vehicle's wiring system.With this installed, it does retain the use of your factory seven-pole connector at the rear of your vehicle. Be sure to connect your wires based off of function and not just rely on color coding.

So, you'll want to test each wire and connect by function. That's the safest, most effective way to make your connections.Now, right here at the seven-way connector, it uses a powerful magnet to join with the magnet in an EZ Connector Trailer End Plug, which is sold separately, and it really provides nice tight secure connection. The plug will stay tightly connected despite the bumps and vibrations common with towing. I do have a trailer end plug, for example, just to show how to make that connection.So, basically what you'll do is you would take the plug from your trailer, lift open the lid, line up the indention with the pin, and allow it to connect, and then you can allow this to come back on top of the plug there. That provides a nice tight secure connection.

It's very easy to use. When you're ready to disconnect, just pull it out and then this is a self-closing lid. That way it covers up those connection points, keeps them safe from dirt, grime, moisture, which is really going to help prevent corrosion.Now, when connected, the system uses face-to-face electrical contacts, so there's no pins or blades to bend or break, which eliminates concerns about electrical arcing and abraded pins. The contacts are also very easy to clean when necessary. The unit features a silicon O-ring on the lid that creates a watertight seal when the lid is closed to keep out moisture and debris, and the unit uses marine-grade wiring to resist water damage.This is a spring-loaded, self-closing lid that automatically covers the connector.

It does come with a hardware bag, so you're going to get detailed installation instructions and all the necessary hardware you need. You get butt connectors, heat shrink tubing, all that's included, as well as a heavy duty zip tie.This is a four-hole mount installation, so you can see there, we got four mounting holes to mount it in the bed of our truck. When it comes to the cable length, we're looking at about 4' long and the product's covered with a limited lifetime warranty. That's going to do it for today's look at the EZ Connector Magnetic Fifth Wheel or Gooseneck Pigtail Harness with Seven-Way Connector.

It works great
But Little expensive

I installed the pigtail on the fitfthwheel today along with the connector into the bed of the pick-up. I found the colors matched exactly on the fifthwheel and was fairly easy to install. I then installed the connector into the bed of the pick-up and found the assembly fit easily into the left rear quarter panel of the 2015 Chevrolet 3500. The wire colors were totally off from the truck wiring so a test light was needed to identify the location of each wire. Once this was completed the install was simply cutting and crimping wires. After the install of approx 2 hours ( I went slow to assure it was correct) I tested the circuits and found that all worked correctly. Looking forward to pulling and seeing how it functions.

  • Solution for Replacing OEM 7-Way With EZ Connector on 2020 Toyota Tundra
    I do have a solution, but there is not an adapter that would allow you to replace the OEM connection and keep the factory look on your 2020 Tundra. Since nothing will match that cutout, I have two options that will allow you to use the EZ Connector on your truck. The first is to use the Trailer Connector Adapter # EZ94ZR. This will plug into your current 7-way and allow you to connect with your trailer's EZ Connector. However, you will either have to leave it plugged in or plug and unplug...

  • What is the Wire Gauge Used in Curt 5th Wheel/Gooseneck Wiring for 2015 Ford F-250
    I spoke with my contact at Curt about wiring harness # C56070. He said that there are 12 to 14 gauge wires used. The 12 volt and ground wires would be the larger 12 gauge. Hardwire harness # 319-S7-08 uses 10 gauge for the ground and auxiliary power, 12-gauge for brakes and 14-volt circuits for the other 4 functions. But the difference between 10 and 12 gauge wire for this application is not going to be a problem so I would stick with the custom harness # C56070.

  • Is There a Replacement Option to Switch In Bed Trailer Wiring 2022 Ford F-450 to EZ Connector Wiring
    The factory Ford connector in the bed of your 2022 Ford F-450 is rather unique and there is not a good way to just replace it with the EZ Connector Magnetic 5th Wheel/Gooseneck Pigtail Harness # 319-S7-08 you found. We do have the Adapter # EZ94ZR you could use or you can more easily splice into the factory 7-way wiring with the Connector # 319-S7-05. As we have never tried this type of installation in our shop you would want to pull away the factory in bed connection to see if it could...
