Your cart is empty.There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials -- running lights, brake lights and turn signals -- while others require a connection for reverse lights, electric brakes and auxiliary power. With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug. For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle's electrical socket and usually requires no additional wiring. CURT offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades and more. This electrical adapter is designed to adapt a 7-way RV blade vehicle socket to fit a 4-way flat trailer plug. It features quality plastic construction, requires no splicing and comes with an LED connector tester dust cover. Not only does this dust cover protect the socket from dirt, water and road grime, but it also allows you to test your vehicle-side wiring connector to ensure your electrical systems are functioning properly..

This works perfect with our 2021 Porsche Cayenne. We had a previous U-Haul adaptor we use for our Honda Pilot but the U-Haul one did not work for the Cayenne. This one did! If you have a Porsche and wondering if it will work, it works perfect for ours. Hope this helps!

I used this to connect a 4-pin lighting set to my SUV’s 7-pin factory trailer wiring. Like the other Curt stuff that I’ve bought, this adapter does what it’s supposed to do. There are probably a couple others that maybe cost a buck or two less, but I’ll go with Curt products every time.

Worked as advertised. I use it on a 23 Blazer for a 4 prong connection to a kayak trailer.

This is exactly what I needed for my new Buick for trailering. It converts a 7 pin into a 4 pin. Plus has lights to make sure it’s working

A little hard to get the protective cap on and off, but all in all works as intended. Love the lights to ensure propre connection. Curt products are made of good quality materials. I recommend

This is an essential piece of equipment, unless of course you love warning beeps and alerts on your dashboard non-stop while you shuttle your lovely bikes around on your rear hitch mounted bike rack, such as the wonderful Kuat NV 2.0. Do not try that without this item.

This adaptor was great quality and easy to use. I love the lights it has that help you confirm the signal is being sent through each wire. Would buy again but it will likely last a long time.
