## Overview

The MECMO Multi-Tow Adapter converts a 4-way flat vehicle socket into dual 4-pin and 7-pin trailer connections, enabling seamless towing of multiple trailer types. Featuring a weatherproof, heavy-duty design with dust covers and a complete mounting kit, it supports all essential trailer lighting and power functions including brakes and auxiliary power. Ideal for professionals seeking a reliable, easy-to-install solution for versatile towing needs.

## Description

There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials -- running lights, brake lights and turn signals -- while others require a connection for reverse lights, electric brakes and auxiliary power. With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug. For this very common problem, MECMO offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle's electrical socket and usually requires no additional wiring. MECMO offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades and more. This special dual-output electrical adapter is actually designed to adapt a 4-way flat vehicle socket to fit multiple trailer plugs, including a 4-way flat and a 7-way RV blade connector. Some manual wiring is required. This multipurpose socket also comes with dust covers, a mounting bracket and all necessary mounting hardware for a complete installation..

Review: 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.
Review: 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

## Questions & Answers

**Q: Will this work on a 2019 jeep**
A: If it has the 4 way flat you can or if jeep has pig for that purpose near the back bumper

**Q: What gauge wire is used?**
A: It looks like it is about 18 gauge. A little lighter than I would have wanted. I wired it with a 20 amp fuse and have not had any problems with overheating wires. I am pulling a medium sized camping trailer with full lights, in-line brake controller, and 3 wireless cameras.

**Q: Will the lights work if I don’t use the brake wires?**
A: Dear Rasa,
Here is a video includes 3 detail wiring diagram of  'MECMO Multi-tow 4 Pin to 7 Way and 4 Flat Adapter'. Since it sounds like you don't need the brake output you can leave the additional connections disconnected. All you will need to do is plug in your existing 4-way to the 4-way plug on the adapter. Once this is done, the 7-way connector will have the functionality of your 4-way. However, if your towed vehicle equip with brake light, you will still need to splice the brake wire to keep all function works.

Thank you
MECMO Service Team

**Q: is it durable ?**
A: Hi dear, MECMO trailer harness use only Amazon FBA which offers all customer free return and replacement. If you receive a defective product or the trailer adapter is under your expectation, you could return or ask for replacement through Amazon. It will be very convenience and does not charge you any fee for replacement in 30 days.

### ⭐⭐⭐⭐⭐ Review
*by K***E on 29 March 2025*

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!!
