Video Transcript for Review of Hopkins Trailer Wiring - 4 Way to 7 Way Wiring Adapter - HM54RV

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Hopkins Plugin 4-Way Flat to a 7 Blade Trailer Connector Adapter. Now basically what this adapter will allow you to do, it'll allow you to use your existing 4-way flat wiring harness that might be on your vehicle with a 7-way plug that'll be on the trailer. So this is great for if you borrow a trailer and it has a 7-way on it, and then you'd have a 4-way on your vehicle. Instead of worrying about how you're gonna make your connection, if you have this adapter, you'll just plug this into the 4-way on your vehicle, open this up, plug your 7-way right in there. Now this will give you all the trailers, the tail light functions that you're gonna need to be legal when towing the trailer.

It'll give you the left and right turn signal, the brakes, the tail, and the running lights. Now, one thing I do wanna mention, even though you plug your 7-way into here, it will not give you the electric brake or auxiliary power functions of a 7-way. It's only gonna give you the 4-way functions. But that should do it for a look at this Hopkins Plugin 4-Way Flat to 7 Blade Trailer Connector Adapter.

Does what it says it does, simple solution for moving my car hauler around (empty) with my Wrangler which has a 4 pole connector. So I can’t get electric brakes or aux power (which I don’t need it it’s empty) but I get all the lights. My only complaint is that the 4 pole wire could be longer, which is why I give it 4 stars.

  • 4-Way to 7-Way Adapter for Trailer Light Functions
    Thanks for reaching out, Jack! What I recommend using is the Curt Adapter # C57672 and securing it to your vehicle with the No-Drill Bracket # 18136. This gives you the ability to seamlessly use either the 4-Way or 7-Way connection but doesn't require you to wire up the 7-Way to be fully functional. For a quick solution we have the Hopkins Adapter # HM54RV, but this won't have any support for the connectors so I see them wearing down so I don't recommend going that route.

  • What is Needed to Add 7-Way to 2019 Jeep Grand Cherokee With 4-Way
    Hey Tim, You can for sure add a 7-way to your 2019 Jeep Grand Cherokee that already has the Curt T-Connector 4-Way # C62VR on it. Are you looking to utilize the electric brakes on your trailer's 7-way? If not you can just use an adapter, the Hopkins Plug-In Trailer Connector Adapter - 4-Way Flat to 7-Blade # HM54RV. This will just give your trailer the same functions as the 4-way, so no electric brakes or 12 volt auxiliary power. However, if you did want the electric brakes and 12 volt...
