A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Ford Transit150, Transit250, Transit350 and Transit350 HD (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup. ## Features - Plugs into vehicle tail light assembly to provide a 4-way flat socket - Simple plug-and-play design eliminates the need for cutting or splicing - 4-way flat output connects tail lights, brake lights and turn signals - Equipped with tail light converter for vehicle-trailer compatibility - Constructed with SMT circuitry for better performance and durability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074H734CS | | Best Sellers Rank | #75,076 in Automotive ( See Top 100 in Automotive ) #185 in Towing Hitch Wiring | | Brand Name | CURT | | Cable Type | 4-Way Flat | | Connector Type | 4-way Flat Output | | Customer Reviews | 4.4 4.4 out of 5 stars (380) | | Global Trade Identification Number | 00612314563272 | | Included Components | Custom Wiring | | Item Dimensions | 9 x 6 x 3 inches | | Item Type Name | Ford Transit-150, 250, 350, HD | | Manufacturer | CURT | | Material Type | Plastic | | Model | 56327 | | Part Number | 56327 | | Recommended Uses For Product | trailer wiring | | UPC | 612314563272 | | Unit Count | 1 Count | | Warranty Description | 1 Year Limited Manufacturer Warranty | ## Product Details - **Brand:** CURT - **Connector Type:** 4-way Flat Output - **Item dimensions L x W x H:** 9 x 6 x 3 inches - **Material:** Plastic - **Recommended Uses For Product:** trailer wiring ## Images ![CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit - Image 1](https://m.media-amazon.com/images/I/81LnHumf4mL.jpg) ![CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit - Image 2](https://m.media-amazon.com/images/I/8117gk9QD1L.jpg) ![CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit - Image 3](https://m.media-amazon.com/images/I/A10wck2XOqL.jpg) ![CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit - Image 4](https://m.media-amazon.com/images/I/918qO0g05BL.jpg) ![CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit - Image 5](https://m.media-amazon.com/images/I/61KMYxigWNL.jpg) ## Questions & Answers **Q: How long does it take to install? I do not have any trailer connector or hitch on my 2018 Transit 350.** A: I took me a little over 2 hours. Start at the drivers side. Tail light is easy to remove. T25 torx, You'll also need to remove the plastic surrounding it only because the wire from the left side is too short for the black box to reach an accessible area. 3 torx, same size, and 2 of those push button pia's. Then a little bit of jiggling to get it around the hinge. I did not disconnect the backup warning sensor on that piece, I just set it on the bumper. Run the green wire to the other side BEFORE you mount the little black box. I had just enough room with the wires a little tight on both sides to put it back together. The stretched wires will dictate where the little black box can be bolted. I used 2 lath screws, one for the ground and one for the box. You could try just one, but I wanted to insure a good ground. I spliced the power wire on the black box wire and ran the wire through an old air hose I had laying around, just for grins. Run it up to the front along with all the other junk going that way and I had enough wire to go to the drivers side and loop to the rearmost terminal on the power box, accessible by popping off the cover that has the red + cover. Splice in the fuse, then the connector. After you are all done, then install the fuse. I recommend looking at utube for better visuals. You do not have to take off the plastic below the taillight on the passenger side. There is enough room to fish it up if you remove one screw and use a screwdriver to get you enough room. This would have been so much easier if Curt didn't cheap out on the wire length for the two tail lights. The one that etrailer sells costs more, but may be worth it if their wires are a few inches longer. I noticed that video shows a extra foot or so of green wiring. I haven't tested it yet as I have a tester coming in the mail and I don't want to move it off the lift until I'm sure it works. A lift makes it easier if you're 70 and it's a hunnert degrees out. **Q: El cable negro qe ba ala bateria ba en el positivo o negativo** A: El cable negro va en el positivo **Q: Says it fits my 2016 transit 350hd but then says single rear wheel only. 350hd is dually. Will this work?** A: Probably not. The plugs that go into to turn signals may be different or some small stupid crap like that, I would call a local parts store get a reference number and come back to Amazon and buy what I need. **Q: What gauge is the black power wire in the kit?** A: the wire is not marked , but it looks like a # 14 ## Frequently Bought Together - CURT 56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Ford Transit-150, 250, 350, HD - CURT 13193 Class 3 Trailer Hitch, 2-Inch Receiver, Fits Select Ford Transit 150, 250, 350, GLOSS BLACK POWDER COAT - Hopkins Towing Solutions 47185 Multi-Tow 4 Flat to 7 Blade and 4 Flat Adapter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/84324880-curt-56327-vehicle-side-custom-4-pin-trailer-wiring-harness](https://www.desertcart.co.za/products/84324880-curt-56327-vehicle-side-custom-4-pin-trailer-wiring-harness) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-31*
