Worried about male to female pins** A: This adapter is for the vehicle side to go from 7 pin to 5 or 4 pin to use with a trailer with either 5 or 4 way wringing. You can not go from 4 or 5 pin on the vehicle to 7 way trailer wiring as your trailer will not get all the functions it needs. Mainly electronic breaks. **Q: Can I run an led lisence plate light off of this adapter?** A: If you can run side marker running lights on a trailer, I am sure you could tap into those. **Q: Can i haul a trailer with electric brakes** A: This will not run electric brakes. It only has 5 of the seven connecting tabs. Two of them are missing, one of which operates the electric brakes **Q: Well this work on a 2015 Nissan pathfinder with factory towing option?** A: I would say yes. As long as you have the round socket for this male plug in. ## Frequently Bought Together - Trailer Plug Adapters 7 Pin to 4 and 5 Flat Blade Trailer Connector for Trailer Tow Hitch, Weatherproof - 4 Way Y-Splitter Plug Universal for Tailgate Light Bar and Trailer Lights Plug & Play Adapter Extension Harness Wiring Plug 4 Pin Connectors (1) - Nilight LED Brake Light Trailer Hitch Cover Square Red Lens Brake Light Vehicle Tow Hitch Driving Brake Lamp 12 LEDs Brake Tail Light with 2" Receiver for Towing Truck RV and SUV --- ## 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.pl/products/148557905-trailer-plug-adapters-7-pin-to-4-and-5-flat](https://www.desertcart.pl/products/148557905-trailer-plug-adapters-7-pin-to-4-and-5-flat) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
