Video Transcript for EZ Connector Wiring - Wiring Adapters - 319-R7-51 Review

Speaker 1: Today we're going to take a look at the EZ Connector Female to 7-Way Male Adapter for the trailer end. Now, this adapter would be used if you've changed your trailer connector on your trailer to the new EZ Connector style. Here's what the EZ Connector style would look like. Then you want to plug this into a standard 7-way RV style plug that's on your vehicle. This adapter's the part you would need for that. This will convert that EZ Connector socket that's not on your trailer to a standard RV style plug on this end.

They do use a powerful rare earth magnet in the plug right here, that will join the magnet in the EZ Connector trailer end socket, and it keeps your connection secure. It's a very strong magnet, so they stay tightly connected despite any bumps and vibrations that are common with towing, they'll still give you a good connection.Now on the adapter, it has the seven flat face-to-face floating spring load electrical contacts. There's no pins or blades to bend or break. Eliminates any concerns about electrical arcing and abraded pins. The contacts are flat so they're very easy to clean when necessary.

If you notice, it has this tab right here, that will align with the notch that's on the plug, so when you go to put it together, all you have to do, the magnet will pull them together, then when you just turn that until that lines up, and then your connector snaps into place. You're all ready to go. Then to remove it again, you just pull it apart. Takes quite a bit of strength to pull it apart. And this part is made in the USA.

But that should do it for the review for the EZ Connector Female to 7-Way Male Adapter for the trailer end.

I have converted my trucks and trailers to the magnetic EZ Connectors. I love them and I recommend them. They are trouble free in my experience. They stay clean and functional in all kinds of weather. From time to time we have someone else using one of our trailers, etc., so having adapters available is a good idea. Great service from etrailer.com

Much easier to disconnect and reconnect, may discourage some thief's as they are not standard unless you have both half's.

  • Can I Use the EZ Connector R7-51 with the Curt Echo
    I was able to reach out to EZ Connector and they confirmed that the # 319-R7-51 will work with the Curt Echo Mobile Brake Controller # C51180 because all of the same circuits would be carried through the 7 way controller just the same.

  • How To Connect 2004 Lance Truck Bed Camper To 2016 GMC Sierra
    I have a replacement connector option, but there is not an adapter to convert the Lance specific connector on your 2004 Lance truck bed camper to a standard 7-way connector on your 2016 GMC Sierra. Instead I recommend replacing the connector with the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector # PK12706. You will need to test the functions of your camper using a 12v battery to power them and the make the connections to the connector following the included diagram. I included...
