Say goodbye to complicated connections and hello to simplicity with the Wesbar Adapter. This multi-function adapter transforms your vehicle’s 7-way RV-style connector into a 4-way or 5-way flat connector, ensuring you can connect your trailer without a fuss. Whether you're towing a camper, boat, or car trailer, this adapter is your go-to tool for seamless connections.
Ever struggled with towing cables that are too short? The Wesbar Adapter features an 18-inch long cable, giving you the perfect length for easy connections without stretching or straining. Whether you’re hooking up to your SUV, pickup, or RV, there's no more tugging on the cables to make your connection reach.
Built to handle the rigors of the road, this adapter features a sturdy molded construction that ensures no exposed wires or gaps. This rugged design not only enhances the durability of the adapter but also provides a secure connection that you can rely on in all towing conditions.
Adaptability is key when towing different trailers, and the Wesbar Adapter has you covered. Whether your trailer has a 4-flat or 5-flat connector, this versatile adapter is designed to seamlessly integrate with both. This means no more purchasing multiple adapters for different trailers—one adapter fits all.
Enhance your towing setup with the included reverse function on the 5-way connection. The extra 5th pin ensures that you can activate reverse lights, perfect for backing up without a hitch. Whether you’re navigating a campsite or reversing into a driveway, this feature keeps your tow vehicle’s movements in sync with your trailer.
Tired of dealing with complex rewiring every time you tow? The Wesbar Adapter’s plug and lead design mean you won’t need to rewire or splice your cables. Simply plug in and go, leaving the hassle of complicated installations behind. Enjoy stress-free towing with smart wiring solutions that work right out of the box.

Today we're going to take a look at the Wesbar 18-inch long adapter, 7-way RV, to a 4-way, or 5-way flat. This adapter will convert the 7-way blade-style connector that's on your vehicle, for use with a 4-way or 5-way flat connector that's on your tow, via car or trailer. Overall length on this cord is 18 inches long, end-to-end, and again, this is the part that would plug into the 7-way blade-style connector. On this end, you can see, there's where a 5-way would plug right into that, and you can also use a 4-way. A 4-way, when you plug it in, you just use the ground, which is the exposed terminal, and then the three right next to it. The end one would only be used if it was a 5-way, because the end one would be for the reverse light circuit.
That should do it for the Wesbar 18-inch long adapter, 7-way RV, to 4-way or 5-way flat connector.
Haven’t used it yet but shipping was very fast.
great product with fast shipping!
For newer Suv's that have the tow package and a 7 pin connector that have no 4 pin connector(they are many) who pull smaller single axle trailers these are a quick and easy way to insure you have lights, and brake light, signal etc. I would have liked to have seen a little less price but I must admit the quality is very good.
Super customer service from Joanne
Works perfect
Very well made works as it should.
Product was great and worked as advertised. My sales assistant, Britany, was extremely helpful. I described what I was trying to do and she recommend the product that helped me accomplish what I needed to fully resolve my trailer connector issue.
The Wesbar Adapter - 7-Way RV to 4-Way or 5-Way Flat - 18" Long is excellent.
The cable is thick, not flimsy. The end connectors are sturdy. It's a good product.
After receiving it today I was able to confidently connect my boat trailer to my Explorer and haul the trailer to get it inspected. Perfect ride. Thanks
Items were exactly as described and the Adapter and oval trailer light (amber). I accidentally ordered the wrong size Trailer wheel center caps (ordered 15" and I needed 14") the staff (Madison) was very helpful and friendly and walked me through the exchange process. Love doing business with etrailer.
It was exactly what I needed. Works well. Got it in great time and exactly what I wanted.
Thank you etrailer

Exactly what we needed for extending the electric connection from our RV to our Jeep. Fits perfectly and gave me just the right amount of length so there is no stress on the connection. Highly recommend

No issues with the product! Holding up tough!
This was exactly what I was looking for!
I've got a flat 5 pigtail on my truck and boat. I bought this so my buddies late model GMC can tow my Ranger 1880MS. I gave it 5 stars but have yet to open the package and try it.
Etrailer has been a life saver for our business! We repair trailers and install truck accessories and have found etrailer to sell name brand parts at much cheaper prices. Melissa A is absolutely the BEST!!
Awesome, this adapters extender and 7 way to 4 way adapter offers a 2_in_1 deal, provide flexibility in connection source and offers extended cable length for connection to various devices.
Found trailer after quick internet search, explained what I was looking for and they steered me right to it. Works perfectly on my 2018 Acura MDX. I ordered and received it in just few days. Would certainly shop here again!
Perfect length for 3/4 ton Chevy with trailer plug in the bumper. Very satisfied and good, timely service. Thanks George.
Excellent quality and the answer for backing trailers using the "key" lockout.
Sturdy and well designed product. I like that the the unit is totally molded to the connectors without gaps or exposed wires.
