## Overview

The CURT 55243 is a custom-fit 7-pin RV blade trailer wiring harness designed specifically for select Ford Super Duty trucks. It offers a seamless plug-and-play installation with no cutting or splicing required, connecting all essential trailer lighting and brake functions. Built with durable, rust-resistant materials and a protective dust cover, it ensures long-lasting, weatherproof performance for reliable towing.

## Description

CURT custom wiring connectors and harnesses are the easiest way to outfit your vehicle with a trailer wiring connection for towing. Each one is custom-fitted to work with a specific make and model. This particular 7-way RV blade socket is designed to be a custom wiring option for certain years of the Ford F250 Super Duty, F350 Super Duty, F450 Super Duty and F550 Super Duty (see application info to verify fitment). It provides a universal trailer connection for the tail lights, brake lights, reverse lights, turn signals, electronic trailer brakes and auxiliary power. 7prong taillight wiring can be used as a replacement or new wiring and is typically used for towing fifth wheel and gooseneck trailers. This 7 way female outlet comes with all necessary hardware to establish a solid connection, as well as a dust cover to keep the connector socket clean when not in use. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this factory tow package socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Instead of cutting, splicing and soldering into your vehicle's wiring system, the custom wiring connector uses a single OEM compatible plug and instantly provides a standard vehicle-to-trailer hitch wiring connection. To ensure long-lasting reliability, all CURT custom tconnector wiring is thoroughly tested for optimal functionality.

## Questions & Answers

**Q: Will this work on 2002 Ford F250?**
A: Worked fine on my early 1999 F350

**Q: For the individual that changed the position of the pins to make this work on a 2002, can you describe how you were able to remove the pins?**
A: I experienced a similar issue - I believe you are referring to the pin layout on the VEHICLE side of this harness, not the standardized 7-pin trailer side.  Ford changed the pin layout for model year 2002 & up, so purchasing a wiring pigtail requires matching your vehicle to the correct Ford part.  Note that BOTH variants of this part will plug into BOTH truck variants, but they will not function properly when mismatched.  You must match your truck year to the proper harness pin layout.  For model years 1999 thru 2001, search for Ford part number YC3Z-13A576-CA.  For 2002 & up, search for Ford part number 2C3Z-13A576-DA. (you'll have to cross those numbers to Curt or other manufacturers yourself)  If you need to change VEHICLE side pin layouts (on THIS harness, NOT the TRUCK), I'd imagine that would require disassembling the back side of the connector, and using a pick or scribe to free the pins from the housing and relocating them to the positions needed on your truck - you'll have to be savvy with a multimeter to map the pins to what you need on your vehicle.

**Q: Is this a 7 blade for an rv?**
A: Yes This is a 7 Way Connector

**Q: Does it work in mt toyota tacoma 2006**
A: It literally says Ford in the description.   It does not say Toyota
