MECMO Multi-Tow 4-Way Flat to 7-Way RV Blade and 4-Way Flat Female Trailer Wiring Adapter Connector Kit, Adapt 4-Way Flat Vehicle-Side Socket to Multiple Trailer Plugs with Mounting Bracket

It came with a good manual (Only one page, but clear and in full colour) All the items needed to install are provided, even small screws.

This adapter worked exactly the way I needed it to. The wiring layout is clear, the connectors feel secure, and everything locked in without any hassle. It’s a clean upgrade if you’re converting from a 4-way flat to a 7-way and don’t want to splice anything complicated. Once installed, it delivered steady power with no flicker or loose signals. Simple, reliable, and a big time-saver. Even ran the brake and battery lead from up front to give me everything I need

Seems to be good quality, the spring on the door flap is nice and tight, all the connectors are put on good and made it simple to install! Bolted right up to my bumper and fits really nice! Plugs into my 4 pin connector and bolt the ground to the frame, then all you have is 3 other wires to connect which if you know what you’re looking for makes install time quick! Definitely a great deal! Only paid $20 for the plug and saved more than that with the time it took to install it!!

Good material with all installation accessories

Very well made trailer connector, conveniently designed for both 4-pin and 7-pin trailer connectors. The instructions are clear and easy to follow. All mounting hardware included. Great to have both style connectors in one unit, for both light-duty and heavier trailers with brakes. I was especially impressed with the professional way the wires were wrapped against chafing. A great value for maximum flexibility.
