Oyviny 7 Pin Round to 4 and 5 Pin Flat Blade Trailer Adapter, 7 Way to 5 Way Trailer Plug Adapter 2-in-1 Design

Perfect fit. I have a 26 palisade and needed to plug a 4 pin and this adapter works perfectly. Easy to install and seems to be good quality.

This adapter is great. It plugs right into a standard 7-pin round vehicle outlet, and on the back side, it gives you the versatility you need. I was able to plug in my standard 4-pin trailer lights and also hook up an extra tailgate light bar I added to the back of my camper for added safety. Being able to run both of them at exactly the same time without any issues is a huge plus. It’s well-built, still working great after plenty of use, and makes adding extra visibility and safety lights to a camper super easy.

It worked well. It is hard to pick the right one and I lucked out. It fit and works perfectly

Works perfectly! Was exactly what I needed to connect to our trailer!

Build quality is good and the connection to the vehicle round 7-PIN is very secure. Grips on the side are good to be able to unplug it. The rubber covers provided have a good seal and protect the 4 and 5 pin connectors from getting wet or covered in dust while they are not in use. I like the ability to use both the 4 & 5 PIN simultaneously. The one concern I have is that the 5 PIN connection is very tight and I can’t slide the connector all the way in. The 4 PIN connection is secure and it has good water seal. The 5 PIN is a harness from the same seller. I can’t tell which one is defective and there’s no way to contact the seller. So, I’ll never know!

I have used it a couple of times with my 2026 GMC Sierra and it worked Flawlessly. Seems to be well made. I have no issues. Thanks

Easy to plug and go works as it should all my trailer lights working out

Fit my 2026 gmc 1500 perfectly and works as intended

Exactly what we needed! Trailer connection for the lights on Honda Ridgeline is different from our old truck. This is perfect. The lights work!

Great product

Used this Oyviny 7 Pin Round to 4 and 5 Pin Flat Blade Trailer Adapter on a 1,700 km trip through Northern Alberta. It held up extremely well through rougher road conditions and long hours of driving. Connection stayed snug the entire time, lighting signals were flawless, and the housing showed zero sign of wear or looseness. Highly recommend if you need a durable, reliable 2-in-1 trailer adapter

Does what it says!

The soft metal of the pins on the 4 and 5 pin side probably won't hold up to daily use, but for occasionally solving the problem of only having a 7 pin receptacle, this setup works for me. Good value for the money.
