It fit great and seems to be built well. Avoid the headache of getting pulled over for a crusty connector. I used this on my motorhome while towing a Uhaul motorcycle trailer. Simple to use. ### ⭐⭐⭐⭐⭐ Review *by J***. on 6 October 2022* Muy buen producto de calidad lo recomiendo ### ⭐⭐⭐⭐⭐ Review *by J***G on 12 August 2015* Pros: inexpensive, built well, rugged, built in tester Cons: None I installed a T-Connecter Kit (also bought from Amazon, CURT 56097) and needed this converter to pull our older model pop up camper. When I installed the T-Connector Kit, I did not have the trailer around to test the signals. Luckily, this adapter has a built in tester which helped confirm that all connections were functioning properly! Nicely built (rugged with a semi rigid rubber casing) and works flawlessly. Drove through the pouring rain and functioned perfectly. I would suggest using some dielectric grease to help weather the connector, but not necessary. Overall, this 7-way to 4-way adapter works perfectly. You will not be disappointed! ## Frequently Bought Together - Hopkins 7 Blade to 4 Wire Flat Vehicle To Trailer Connector Adapter Plug, Universal Fit for Vehicles with 7 Blade Adapters (47345) - MaxxHaul 80778 Magnetic Towing Light Kit (Dual Sided for RV, Boat, Trailer and More DOT Approved) - 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.co.uk/products/267770573-hopkins-47345-4-wire-flat-adapter](https://www.desertcart.co.uk/products/267770573-hopkins-47345-4-wire-flat-adapter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
