## Overview

The CURT 56070 is a 7-foot custom wiring extension harness designed to add a 7-way RV blade socket inside your truck bed while retaining the rear bumper socket. Compatible with select Chevrolet, Ford, GMC, Nissan, Ram, and Toyota trucks, it offers a plug-and-play installation with no cutting or splicing required. Perfect for 5th wheel and gooseneck trailer connections, this durable, weather-resistant harness ensures seamless towing power and convenience.

## Description

There is nothing like the luxury and power that go along with heavy-duty towing. 5th wheel RVs offer a deluxe, home-away-from-home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, 5th wheels and goosenecks must be equipped with the proper lighting and electrical systems, and tend to require even more complex connectors than a standard receiver-type trailer setup. Make things simple with a CURT 5th wheel / gooseneck extension harness. These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your 5th wheel or gooseneck trailer. This CURT extension harness is designed to work with 7-way RV blade connectors and comes in a length of 7'. It is compatible with a certain models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota (see application to verify fitment). When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, CURT gets you plugged in.

Review: Excellent - The Plug and play design makes it easy to install on my Silverado. Works great. Plenty of length for my 8ft bed and pretty tough plastic.
Review: Easy mounting. - This is the way to go if you need to replace your seven pin RV whip. Fit flawlessly in the bed of my truck and easily plugged into my existing one on my 2019 F350. Would recommend.

### ⭐⭐⭐⭐⭐ Plug it up
*by S***S on February 19, 2025*

I had a flat bed put on my truck and I wanted to put a plug in with my ball and this made it super easy to do. The plugs fit right up to the plug coming off my truck and was able to plug right up to the plug on the back of the bed. And it’ll be super easy if I ever want to take this off and change it to a different truck. It works amazing ! A very thought out design!
