This fits perfectly and works great ### ⭐⭐⭐⭐⭐ Good quality would buy again *by on Reviewed in the United States June 14, 2026* Works great ### ⭐⭐⭐⭐⭐ Works *by on Reviewed in the United States July 5, 2026* 1998 Dodge Ram Magnum 1500. Works great, fits perfect. The fact that you have the flex extension is perfect because there isn't much room between the hitch and plug. ## 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.fr/products/503930120-7-way-blade-to-4-way-flat-trailer-adapter](https://www.desertcart.fr/products/503930120-7-way-blade-to-4-way-flat-trailer-adapter) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-25*
