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 special dual-output electrical adapter is actually designed to adapt a 4-way flat vehicle socket to fit multiple trailer plugs, including a 4-way flat and a 7-way RV blade connector. Some manual wiring is required. This multipurpose socket also comes with dust covers, a mounting bracket and all necessary mounting hardware for a complete installation..

Arrived faster than if it was shipped to my business or home. Perfect sealed clamshell package. Is authentic CURT Mfg. Easy install, as easy as anything can get when you have to slide under your pickup and work looking up. Nice features like the wires already with connectors, ready to crimp. have not had a chance to tow with it yet, will update if there is a problem. Of note: this is my 2nd replacement. My Curt Echo Bluetooth Trailer brake controller, which get's mounted into this Curt Connector, that Echo is very very tight and to remove it, I had to yank and yank and it finally came out, but with the power blade from the connector stuck in the Echo controller. I've done this twice, and both times had a pro install the new connector at a couple of hundred bucks each time. I finally decided to install myself, save 200+ bucks and it went in very simply. I've filed any corrosion off the Echo internal connectors, added some diaelectric grease and now the controller comes out of the 7-way Curt socket with no damage to either part. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/255699521-57672-dual-output-4-way-flat-vehicle-side-to-7](https://www.desertcart.com.ar/products/255699521-57672-dual-output-4-way-flat-vehicle-side-to-7) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-21*
