Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

I had previously installed a receiver hitch from etrailer and didn't install a wiring harness until I was ready to tow my trailer, I'm glad I delayed my purchase! The price had dropped substantially. Easy install, just follow the instructions.

A year later and the wiring harness still works like a champ!

Land Rover Discovery II

Easy to install especially with the discovery of a live wire to the battery taped to the light harness behind the grommet of the left taillight. Saved this old body from having to crawl under the care to install the power lead for the control box. Also made the install a 30 minute job instead of an hour and 30 minute. Arrived in a timely manner and well worth the price.

The product was great! Easy to install and quite reliable. Highly recommend. Just follow the directions.

Easy to install. Should include a second tie for the 4 pole wire to attach to the hitch due to the wire length. Overall I will recommend this product to others.

  • Does the Drawbar Included with the Hidden Hitch Trailer Hitch # 60832 Have a Hollow Shank
    I went out into our warehouse and inspected the drawbar that comes included with the Hidden Hitch Trailer Hitch Receiver with Drawbar - Custom Fit - Class I - 1-1/4 inch, part # 60832 (no longer available), and it has a solid shank. The included Class I drawbar, that is designed for 1-1/4 inch, hitch openings has a tongue weight capacity of 200 lb, and gross trailer weight limit of 2000 lbs.

  • Recommendation For Hitch That Clears The Muffler On A 2010 Jeep Compass
    Having the exhaust system contact and rattle against the hitch is a fairly common occurrence that can happen with just about any vehicle. You can install the hitch on two identical vehicles, and it'll rattle on one and not on the other. When the hitch is installed, it's in a static or fixed postion. It will not move. Due to the rubber isolators used to install exhaust systems, the exhaust system can move around a bit and its exact location can vary a bit from vehicle to vehicle. There's...

  • Only Passenger Side Brake Light Works on 2008 Jeep Compass After Installing Trailer Wiring Harness
    A bad ground can cause all sorts of problems, but I am not convinced this is a ground problem. However, it could be beneficial to try to move the ground location to see if that helps. Wiring harness # C55050 receives power for the trailer lights from the vehicle battery and only a little bit of power and signals from the vehicle tail light wiring. If the power wire is not connected, the harness should not work. Try disconnecting the harness from the vehicle tail lights and plug the tail...

  • Troubleshooting Tekonsha 4-Way Trailer Connector with Only Running Lights on 2008 Pontiac Torrent
    The relays and fuses that are included with the # C55050 wiring harness are correct for your 2008 Pontiac Torrent. The two relays need to be installed into positions 58 and 59 for the right and left turn signals and brake lights. Also, 10 amp fuses need to installed into positions 37 and 43 for the same functions. If this is all correct I would inspect the connector the harness plugs into in the rear cargo area. Make sure none of the pins are bent or damaged. If they're bent you can...

  • Will A Short In The Trailer Wiring Short out The Converter Box On A 2008 Jeep Compass
    Yes, a short on the trailer wiring will take out the converter on your 2008 Jeep Compass. You will need to inspect the trailer wiring on the left side of the trailer to locate where the short is and repair it. The LED lights on the trailer will not be causing any problems with the converter. I am sending a link to an information page that will describe how to troubleshoot your trailer wiring.

  • Trailer Hitch and Wiring Harness for 2007 Dodge Caliber R/T AWD
    I apologize but at this time our manufacturers are only producing hitches for the SE and SXT models, not the R/T. The R/T is a performance minded model and due the differences between the R/T and SE/SXT models, a hitch cannot be safely attached to the frame.

    The only trailer hitches available for a 2007 Dodge Caliber are Class I trailer hitches that have a 1-1/4 inch receiver opening. They also have a 200 pound tongue weight capacity which is not going to be high enough to support the weight of the bike and carrier. A higher capacity hitch is not available because the vehicle cannot support the weight. Make sure to consult the vehicle owners manual in the towing section to determine the towing capacities of your Caliber. What I recommend...

    I called the manufacturer (Tow Ready) and they said there is no difference in the taillight wiring harness for the 2007 Dodge Caliber and the Caliber R/T. I also checked with a fellow worker here who worked in the Chrysler/Dodge factory that made the Caliber and Caliber R/T. He said that he installed the taillights in the same vehicles and that they are the same taillights.

  • Hitch Recommendation for a 2007 Dodge Caliber Towing a Jet Ski Trailer
    It's very possible that you could tow a Jet Ski with your 2007 Dodge Caliber but you will need to check a few things first. You will need to know what the owners manual of the Caliber says is the towing capacity for the vehicle and you will need to know the weight of the trailer with the Jet Ski loaded on it. If the Jet Ski weighs less than the weight capacity for the vehicle you would be OK to tow with it. Now for a hitch you would want the Draw Tite hitch part # 24769. I attached an...

  • Trailer Turn Signals Not Working with # C55050 Wiring Harness Installed on a 2008 Jeep Commander
    It sounds like you have one of two problems. First, I would check the wiring harness at the back of the vehicle. Disconnect the trailer and make sure the ground wire is connected to a clean, rust, paint and corrosion free ground location. Then using a circuit tester, item # PTW2993 if needed, test the wires going into the converter. The red wire should have the brake signal on it, the green wire should have the right turn signal on it, the yellow wire should have the left turn signal on...

    The 4-pole trailer wiring harness kit made for your 2008 Jeep Compass, parts # C55050 from Curt, is powered-type harnesses that do require a direct battery connection for powering the converter and the trailer's lights. The kit # 118425 that you referenced, which fits only the Jeep Grand Cherokee, cannot be used on your Compass because it would not provide the protection for your car's wiring that these other harnesses do. Here is why. The internal wiring in the Compass is much lighter...

    This may seem like an obvious suggestion but you will need to make sure the T-Connector Vehicle Wiring Harness, # C55050, is directly connected to the positive battery terminal on the vehicle via the included fuse and holder. Any other 12 volt source is not sufficient. Make sure the fuse is intact and fully inserted into the holder. If you have done this and followed all of the other instructions and there is still no power or signals coming through then there could be a problem inside...

  • Troubleshooting Curt Vehicle Wiring Harness # C55050 on a 2007 Jeep Patriot
    It sounds like you have a bad ground somewhere. When you turn on the headlights the maximum amperage draw is on the trailer connector, and this causes marginal ground connections to show up. I would start by checking the ground connection on the wiring harness on the vehicle. Make sure that it is grounded to a good clean point and that the screw is tight and not stripped out. If the ground is good use a circuit tester, item # PTW2993 if needed, and check the trailer connector, with the...

    This Draw-Tite Trailer Hitch, part # 24769, has towing capacities of 2000 lbs total trailer weight and 200 lbs tongue weight. If your boat and trailer weighs less than that this hitch would be adequate for you. You should also consult the owners manual of your 2007 Dodge Caliber SXT for the towing capacity of your vehicle. You should always go with the lowest towing capacity of all the components of your towing setup when determining your overall towing capacity. If you determine that...

  • Is Installation of the Power Wire Required for Trailer Hitch Wiring on a 2007 Dodge Caliber
    The T-One Vehicle Wiring Harness, # 118552, for a 2009 model Caliber or the Curt # C55050, for a 2007 Caliber, powers the trailer lighting from the vehicle battery. If you do not connect the power wire to the vehicle positive battery post, the harness will not function properly and the vehicles sensitive wiring and circuitry would be at risk of damage if a short circuit would occur on the trailer wiring.

  • Will the # 75712 Draw-Tite Class III Max Frame Trailer Hitch Fit on a 2007 Jeep Compass
    Yes, the Draw-Tite Class III Max-Frame Trailer Hitch, # 75712, is a confirmed fit for the 2007 Jeep Compass. The Draw-Tite Class II Trailer Hitch, # 36423, is also a confirmed fit for your Compass. The main difference between these two hitches for your vehicle is that the Class III hitch is going to provide you with a 2 inch receiver opening which will allow many more accessories to be used in the hitch. If you plan on towing with your 2007 Compass, you will need a wiring harness, #...

  • Suitability of 2008 Jeep Compass for Towing Trailer Weighing 1800 Lbs
    If the weights you have given me are correct, you should be able to tow the trailer. Keep in mind that you are less than 200 lbs away from your towing capacity. Any extra gear on that trailer could place you over the towing capacity of your Compass which could possibly cause damage to the hitch or the vehicle. Since you are so close to the towing capacity of the vehicle, a transmission cooler would be a wise investment. I would recommend the Derale Dyno-Cool Tube-Fin Transmission Cooler,...

  • Is a Ball Mount Required to Tow Trailer with 2007 Dodge Caliber
    Draw Bars are needed for towing. Another name for them, that to me makes more sense, is "ball mount" Basically this is the piece of metal that inserts into the hitch opening that holds the hitch ball for your trailer to connect to. If you want to tow with your 2007 Dodge Caliber you will need a ball mount. First you need a hitch installed though. For that the Draw Tite part # 24769 is the correct fit. And then for a ball mount/draw bar you'd want the part # 3591 which is what Draw Tite...

    Since the converter has power entering but not exiting it, it has been shorted out and will need to be replaced. The exposed piece of wire on that right turn circuit could certainly have caused the problem by contacting a metal surface under the vehicle and causing a short. The vast majority of the time, when a converter fails it is due to a short circuit on the trailer itself. Take a few minutes and closely examine each lighting circuit on your trailer, from the connector itself to the...
