Installation

This custom-fit T-connector plugs into your factory tow package wiring harness, which is located beneath the rear of your vehicle, along the driver's-side frame rail.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 7-pole connector itself - to help prevent corrosion.

I do a lot of product reviews. If at any time in the future you want a product review, just let me know, and you can send me a product to try and write a review. It is sort of a hobby of mind. I love doing reviews, and trying new products. Just in case you are interested, my address is: Jerry W Mann Product review 12900 Raleigh Road Benson, NC 27504-6812 (919) 749-5290 The Wiring Harness that you sent to me is of great quality. Actually better than OEM. The wires are of a heavier gauge, and the plug fits like a charm. Everything works as it should with no issues what so ever. Thanks for having a great product. 770227

  • Recommended 7-Pole Wiring Harness for 2004 Ford F-350 with Factory Tow Package
    I do have a wiring solution for you, but the Curt T-Connector Vehicle Wiring Harness # C55243 you referenced is not compatible with your truck. It is designed for certain models of 1999-2001 Ford Super Duty trucks. For your 2004 Ford F-350, you can use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55774, as long as your vehicle is equipped with a factory 7-way connector. If your F-350 is equipped with a factory 4-flat instead, you can use Curt T-Connector...

  • Replacement OEM Electrical Connector For Factory Tow Package Wiring On a 1998 Ford F-150
    Unfortunately we do not carry the OEM replacement pigtail for the 1998 Ford F-150. You would have to try a Ford dealership, auto part store, or salvage yard. If they do not or cannot get the replacement you can always cut the plug off and hard wire the ends together. I recommend using Deka Heat Shrink Butt Connector - 12-10 Gauge - Nylon Insulation - Yellow - Qty 10 Item # DW05745-10 when connecting the wires. These will protect your connection from corrosion and get your 7 pole plug working...

    You can use the Curt T-Connector Wiring Harness, # C55243, or the Tow Ready Replacement 7-Way Harness, # 118243, on your 1999 Ford F-250 Super Duty. These are basically the same item for your truck made by different manufacturers. If the price point of the Curt harness is more appealing to you, then there is no reason why you cannot use that harness. There is one thing you will want to keep in mind when installing either of these harnesses, do not forget to install the relays and...

  • Adding a 7-Way Trailer Connector to a 2000 Ford Excursion
    The Curt trailer wiring harness # C55243 doesn't fit but I can recommend the parts to add a 7-Way trailer connector to your 2000 Ford Excursion. First, if the Excursion has a 4-Way flat connector now then you will just need # ETBC7 to add the 7-Way, keep the 4-Way, and have the wiring and accessories to wiring in a brake controller. If your Excursion does not have any trailer connector at all then you will first need to install a 4-Way using # 118344 and then you can install the...

  • Converting 4/6-Way Factory Connector on 1999 Ford F-350 SD to a 7-Way RV-Style Connector
    You identified the correct harness to convert your 1999 Ford F-350 SD from a 4/6-way trailer connector to the more common RV-style 7-way blade type. Part # C55243 will plug in to a square OEM connector along the driver's-side frame rail. You may want to use metal 7-way mounting bracket # PK12711U to simplify installation. The linked photo will show you the type of connector you are looking for under the frame.

    We do offer replacement connectors that will work with your OEM wiring harness on your 2008 Ford F-250. If you just need the replacement 7-pole connector, I recommend part # PK11893. This is an exact replacement for the OEM connector on your truck. If you find the vehicle side of the harness was damages, I recommend part # C55242. This plugs directly into OEM tow package wiring harness and requires no cutting or splicing of wires. To get a 6-pole connector on the rear of your...

  • Difference Between Curt and Tow Ready 7-Way Trailer Wiring for 1999 Ford F-250
    They are basically the same thing but are two different brands versions of 7-way trailer wiring for your 1999 Ford F-250. The part # C55243 is made by Curt and # 118243 is made by Tow Ready. Either would work great.

  • Replacement 7-Way for a 2002 Ford F-350, 450, and 550 Cab and Chassis
    The pin locations for the Curt T-Connector # C55243 are different from your connector because the 55243 fits a 1999 - 2001 Ford F-250 and F-350 Super Duty with factory 4-flat. Since you input your vehicle info as a 2002 Ford F-350, 450, and 550 Cab and Chassis the only replacement options we have look like the Curt # C55774 which plugs into the US Car Connector which would be on the other end of your wiring harness. If just the 7-Way on your vehicle is needing to be replaced then the 55774...

    If your 2000 Ford F-250 Super Duty came with a factory 4-Way, then the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55243 referenced in your question is indeed the correct harness to install a 7-Way. The wiring from the back of the trailer connector to the port that will connect to your truck is not currently available as a separate item. This kit will include the 7-Way trailer connector. This will plug right into the factory wiring harness located beneath the...

  • Do I Need to Install Fuses and Relays on a 2000 Ford F-250 for Towing
    Yes, there are relays and fuses that will need to be installed on a 2000 Ford F-250 if not already present in order to activate the circuits for the brake controller and 7-way trailer connector. In order to check this you simply need take a look at the power distribution center. If there are fuses in both the Trailer Tow Electric Brake and Trailer Tow Battery slots as well as relays in both the Trailer Tow Backup Lamp Relay and the Trailer Tow Battery Charge Relay slots then you are good...

  • Recommended 7-Way Trailer Wiring for 2000 Ford F-250 7.3 Diesel
    For your 2000 F-250 Diesel the trailer wiring you need depends on what your truck came with. If you have the factory 4-way then you would simply use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C55243 to give you the functioning 7-way. You will also need a brake controller and harness if you want all the functions. I've linked the page to your options.

  • Recommended Wiring Harness for 7-Way on 2004 Ford F-250
    I reached out to Curt and they said they do not have anything like that to fit anything past 2001 due to wire patents. So to get your 7-way, you will need to first get your 4-way connector. If you have the factory 4 way option, then you can use # C55265. If you don't have the factory wiring harness you will need # 18252. Once you have the 4-way flat, you can then use # ETBC7 to get the wiring connections, and circuit breakers for 7-way connection. If you want to add a brake controller...

  • Where Does Curt T-Connector Vehicle Wiring Harness Install on a 1999 Ford Super Duty
    T-Connector is a generic term that is applied to any trailer wiring harness that is plug and play. Models of the 1999 Ford Super Duty that came with a factory 4-Way would use the connector # C55243 to just plug in where the 4-Way plugs in.

  • Parts Needed to Add a 7-Way and Trailer Brake Controller to a 2001 Ford Expedition
    On a 2001 Ford Expedition that did not come with a factory 7-Way, you will actually need to use adapter # 37185 to add a 7-Way. To connect the 4-Wires on the 37185 you will need to first ground the white wire to the truck frame. Then you will want to follow the factory wiring forward on the vehicle to where it plugs into another connector. On the connector on the forward side, there are more wires going in then coming out. If you pull back the covering on the wires you will find some...

  • Fifth Wheel 7-Way Recommendation for a 2016 Ford F-350 for Bed of Truck
    What I would actually recommend for you is the part # 41157. This is a harness designed for exactly what you are looking for. It will plug in line with the 7-way you have at the rear of your vehicle and will give you a second one for you to install up near the wheel well for the fifth wheel. I attached an install video for you to check out as well.

  • Troubleshooting Ground Wire of Trailer 7-Way Wanting to Pull Out
    I'd have to see what type of connection your 7-way makes, but if it's a set screw you'll want to make sure you are getting plenty of wire into the slot and then tighten it down so that it can't easily slip out. Also make sure you don't have trailer wiring that's just too short and wants to pull itself out when you make tight turns as the cable starts pulling.

  • 6-Way Round to 7-Way Flat Recommendation for a 2000 Ford Expedition
    To go from a 6-way round on your tow vehicle to a 7-way blade you would want the Adapter 6 Pole to 7 Pole Trailer Wiring Adapter # 47435. With this adapter your brake controller will remain functional as the brake output circuit is on the adapter.

  • Replacement 4 and 7-Way Trailer Connector for a 2000 Ford F-350
    You can use the Hopkins 4/7-Way connector # HM48470. All you will need to do is attach the wires from the old connector in the same places on the back of this connector then mount it where you want it. No other wiring harnesses are needed. The replacement 7-Ways we have for a 2000 Ford F-350 that also have the rectangular plug do not have a built-in 4-Way. We have # C55243 and # 118243. You could use one of these and then use an adapter, # HM47570. If the truck came with the factory...

  • What is the Towing Capacity of a 1999 Ford F-350 with V10 Engine
    The maximum conventional towing capacity of your 1999 Ford F-350 is 5,000 lbs at the bumper and 10,000 lbs at the trailer hitch. If you are looking to tow under 5,000 lbs then all you would need is a hitch ball like the 2" Hitch Ball part # 40038 or the 2-5/16" Hitch Ball part # C40007. However, if you looking to tow in excess of 5,000 lbs then you would need a frame mount trailer hitch like the Curt Trailer Hitch Receiver part # C15316 which is a custom fit that provides you with a 2"...

  • Available OEM Trailer Wiring Harness Kits for 1999 Ford F-250
    Hopkins Plug-In Simple Wiring Harness # HM40155 has a 4-pole flat trailer connector and is intended as a replacement for a factory 4-pole on your 1999 Ford F-250. We do have other wiring kits for your truck depending on how it was equipped from the factory; all kits are shown on the linked page. For example, parts # 118243 and # C55243 are 7-way kits that include fuses and relays to activate the additional circuits for the trailer.

  • Recommended Trailer Hitch Options for 1995 Ford F350
    We have many different hitches compatible with your truck. The best choice for you will depend on what you're wanting to tow. For lighter duty towing, I'd recommend the Class III hitch, part # 75038. The hitch has a 5000 lb towing/500 lb tongue weight capacity. For a heavier duty Class IV, the Curt # 14001 with its 10000 lb towing and 1000 lb tongue weight capacity would be a good choice. For a higher capacity, B & W offers a Class V with a 2 inch by 2 inch receiver opening, part # BWHDRH25122...

  • No Power at 7-Way Charge Circuit On 1999 Ford F-250
    The relay box on your 1999 Ford F-250 is actually located in the engine compartment near the brake master cylinder. Since it sounds like you don't have power at the 7-way at all you probably need a new 30A fuse in location 16 for the trailer battery charge. The battery charge also has a relay in location 39. If you replace the fuses and still do not have power at the 7-way you most likely need to replace it. If the Ford has a factory tow package, you can replace the plug with part #...

Then you will need to use the Hopkins Endurance Multi-Tow 7-Way RV and 4-Way Flat Trailer Connector - Vehicle End # HM40950 to get both functions readily accessible.

    The Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975 does not come with any wiring, just the socket and a mounting bracket. If the wiring on your 1999 Ford F-250 Super Duty is shot back to the factory square gray plug then you will need to use some replacement wiring. If you use the Curt T-Connector # C55243, it will give you the wiring that you need. You can then use the Pollak # HM40975 instead of the 7-Way socket that is provided with the Curt T-Connector package...
