Thank you for viewing. RV and trailer brake control wiring set, including a 7-blade connector and a 4-flat pin connector. I purchased this for use in my car, but I found other parts that could be installed without modification, so I am offering this for sale. There may be some minor scratches on the outer box due to direct import from America. The product itself has never been used and has been stored in a warehouse. I will lower the price by 10 yen every day at 8 PM. If you are interested in buying at this price, please comment. I am open to price negotiations. 7-Way RV Plug Adapter for Brake Control Wiring, compatible with 4-Flat connectors, includes all necessary components for installation. - Type: Brake Control Wiring 7-Way RV Plug Adapter - Features: Duplex Wires, Ring Terminals, Circuit Breakers - Compatibility: For vehicles with a 4-Flat connector - Components: Includes 7-Way adapter, wiring harness, and connectors - Installation: Designed for easy installation with existing wiring
