Compatible with major truck brands like Chevrolet, Dodge, Ford, GMC, Nissan, Ram, and Toyota, it offers a simple plug-and-play installation with no cutting or splicing required. Perfect for 5th wheel and gooseneck trailer wiring, it supports all essential trailer lighting and braking functions, making heavy-duty towing safer and more convenient. ## 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. ## Features - 7' Custom Wiring Extension Harness (Adds 7-Way RV Blade to Truck Bed, Packaged) - Routes a 7-way RV blade socket into truck bed while retaining use of rear socket - Simple plug-and-play design eliminates the need for cutting or splicing - Allows for easy connection of 5th wheel or gooseneck wiring - 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0031GHBSE | | Best Sellers Rank | #29,217 in Automotive ( See Top 100 in Automotive ) #55 in Automotive Replacement Electrical Wiring Harnesses | | Brand Name | CURT | | Cable Type | flexible | | Connector Type | 7-way Rv Blade | | Customer Reviews | 4.8 4.8 out of 5 stars (2,473) | | Global Trade Identification Number | 00612314560707 | | Included Components | Wiring Extension | | Item Dimensions | 8.7 x 8.2 x 4.1 inches | | Item Type Name | Extension, Select Chevrolet, Dodge, Ford, GMC, Nissan, Ram, Toyota | | Item Weight | 2.25 Pounds | | Manufacturer | Curt Manufacturing | | Material Type | Plastic | | Model | 56070 | | Part Number | 56070 | | UPC | 612314560707 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year Limited Manufacturer Warranty | ## Product Details - **Brand:** CURT - **Connector Type:** 7-way Rv Blade - **Item Weight:** 2.25 Pounds - **Item dimensions L x W x H:** 8.7 x 8.2 x 4.1 inches - **Material:** Plastic ## Images ![56070 7' Truck Bed 7-Way RV Wiring Extension for Select Trucks - Image 1](https://m.media-amazon.com/images/I/71xWDvj-NeL.jpg) ![56070 7' Truck Bed 7-Way RV Wiring Extension for Select Trucks - Image 2](https://m.media-amazon.com/images/I/61uVato7dWL.jpg) ![56070 7' Truck Bed 7-Way RV Wiring Extension for Select Trucks - Image 3](https://m.media-amazon.com/images/I/81Vr3gARgHL.jpg) ![56070 7' Truck Bed 7-Way RV Wiring Extension for Select Trucks - Image 4](https://m.media-amazon.com/images/I/91JOxXhPHkL.jpg) ![56070 7' Truck Bed 7-Way RV Wiring Extension for Select Trucks - Image 5](https://m.media-amazon.com/images/I/71g1AhDt5gL.jpg) ## Questions & Answers **Q: Will it fit a 2021 Dodge Ram 2500?** A: Yes this will fit your 2021 Dodge Ram 2500 **Q: Will this fit my 2004 chevy 2500hd?** A: It should fit, worked great on my 2003 2500 HD. **Q: Will it fit a 1999 ford super duty** A: Fit my 03!
