## Overview

## Description

This 7-way round RV blade connector is designed to supply power for tail, brake, reverse, turn signals, electronic trailer brakes and auxiliary power, as well as a ground connection. Easy installation direct plug into vehicle wiring to provide a connection for a trailer plug, interchangeable with other 7-way RV style connectors common used on RV travel trailers. It features rust-free black plastic construction and equipped with a spring-loaded cover to keep connector away from dust and water. Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. MECMO electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 7-way OEM USCAR replacement connector is designed to plug into a twist-in OEM vehicle socket and supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It features rust-free black plastic construction and comes with a spring-loaded cover to keep out dust and water. This 7-way RV blade connector is a female-end socket, specifically designed for the vehicle side of the connection (see application info to verify fitment with your vehicle).

Review: Saved my butt when the previous owner of my grand Cherokee sliced off the 7 pin connector and left me with bare wires. This kit includes everything you need to wire it back up. Worked great. Only thing is, the wire colours are different on the vehicle harness vs this product. It comes with a colour code wire diagram. You will need one from your vehicle so you can match the right wires up.
Review: It took a while to match the wires to the trucks wires but everything works amazing. It’s got plenty of wire and looks sturdy . Installation took about 4 mins once we got the wiring matched . Took it on a 400mile trip with no issues !
