This works perfectly when you need to convert form a 7pin to a 3 pin for light duty trailers! Great product ### ⭐⭐⭐⭐⭐ Great buy for new trucks with 4 wire trailers *by C***S on April 17, 2026* Works great on 2025 GMC 1500, no problems and works with the bells and whistles on the GMC Trailer towing package. ### ⭐⭐⭐⭐⭐ Great little adapter - buy 2 its such a good deal *by J***. on January 25, 2026* Plugged right in and worked immediately. The only negative, is its the type of thing that seems to "walk off" on its own so you will end up buying more.. They're so cheap I would recommend you buy 2 anyways, that way you don't have to be frustrated when you go to use it and it's gone. ## Frequently Bought Together - Oyviny 7 Way to 4 Way Trailer Plug Adapter, RV Blade 7 Pin Round to 4 Pin Flat Trailer Light Adapter 11.6 Inches - Oyviny 7 to 4 & 5 Pin Trailer Adapter, 2-in-1 Design --- ## 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.tn/products/503930120-oyviny-7-way-to-4-way-trailer-plug-adapter-rv](https://www.desertcart.tn/products/503930120-oyviny-7-way-to-4-way-trailer-plug-adapter-rv) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
