Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


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.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. 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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C55502 Review

Today we're going to review part number C55502. This is the Curt T-Connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. This is a custom fit part number. It is designed to fit the Acura TSX model starting in 2006 and the Honda Accord model starting in 2003. What I would recommend is to go to our website and on our fit guide type in your year and model vehicle, and it would show you if this harness will work for your application. This does provide a 4-way flat trailer connector at the back of your vehicle to power the trailer's signal lights.

It does connect quickly and easily. There's no cutting or splicing of wires. Basically, you locate your connection points in the rear cargo area, plug in these T-connectors behind the tail lights, and you'd be ready to go. It does include this tail light converter to ensure that you vehicle's wiring will match that of your trailer. This converter is constructed using the SMT or Surface Mount Technology. It gives you consistent, reliable performance.

This will maximize your trailer light yield and intensity while producing minimal heat and it does ensure superior operation even in rough road conditions. This part does include everything shown here. Comes with this dust cap which, when you're not using your 4-way, you can just put this on just like that. Then your cap would right over it to protect it when you're not using it. Does come with a large zip tie and some smaller zip ties to take up any extra wiring and keep it from hanging down. Comes with a ground screw.

It comes with a double face piece of tape to attach this converter box to your vehicle, and a nice set of instructions with some good diagrams . shows you where all the connection points are. The maximum amperage on this, the stop and turn light system, is 3 amps per circuit. The tail light system is 5 amps per circuit. Basically when you go to install this, what you would do is this length of the 4-way with the length of where I would run out the back of your vehicle.

Then what you'd do is remove the threshold on the back of the vehicle, and what you'll do is these T-connectors right here will plug into the back of the tail lights on each side. The yellow would go to the driver's side, this one will go to the passenger side. There is a white wire that needs to be grounded to a good, clean ground. You can use an existing screw or use the included ground screw that they include in this. The last wire is a single green wire with a connector on it. There's actually the connector that will match this again on the driver's side threshold area right below the tail lights. Once those are all connected, you should be ready to go. You'd plug this into your trailer and you'll be able to tow and get lights on your trailer. That should do it for the review on part number C55502, the Curt T-Connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. .

I received this receiver about 5:00 PM only three days after ordering it. I called the customer and he delivered his car at 7:00 PM. I installed the the receiver, the taillight converter and wiring, called the customer back and He picked it up ready to tow his trailer by 8:15 PM. That is amazing. Flawless fit and function. That is how to satisfy a customer. 547871

Great product. This one utilized the reserved tow light connector on my Accord, unlike other products (they have long green wire) that need to take off both liner to access left and right signal wires, I just need to take off the left liner and every socket you need is there. 508340

This did not fit my 2010 Acura TSX. 95% of it fit, but I did not have a plug for the right directional (the single green wire) on my car as the instructions said. So, I ended up tapping into the directional wire in the cars wiring harness (also green) with a quick splice wire tap. That worked fine, and only held me up a bit. I don't know what model car this one does fit, but it's not a 2010 Acura TSX. 259945

As outlined in my hitch review I also purchased etrailer's wiring harness. Make sure you find a video on utube that shows you how to remove the back trunk panels. It would be eazy to break the plastic mounting pins. I found one that showed how in a video on attaching a wiring harness. It was a easy as one two three. Just unsnap each of the three tailights from their factory plugs, replug each of the wiring plugs on the wiring harness and replug the factory plugs into the wiring harness.additional leads. You cannot plug into the wrong one as each is unique to its own. Place a couple of tie downs on the harness to anchor it. I placed the end of the harness plug into my spare tire well, replaced the trunk panels and job done. When I need to plug in the harness to my trailer I just lift my spare tire cover, pull out the desired length to reach the traile plug and close the trunk lid. 198242

  • Recommended Curt Class I Trailer Hitch Receiver for 2005 Honda Accord
  • You are correct in how the Curt Trailer Hitch Receiver -Class I - 1-1/4" # C11290 is mounted. This hitch has been tested to hold a maximum tongue weight of 200 lbs and a maximum trailer towing weight of 2,000 lbs when loaded. A riding lawn mower on a small trailer is probably at close to the maximum capacity of this hitch, so I recommend calculating the weights before doing this as your owners manual states 1000 lbs towing max and 100 lbs tongue weight. For your trailer wiring, I...

  • The Curt Trailer Hitch Receiver - Class I - 1-1/4" # C11085 is a fit for the 2008-2012 Honda Accord Sedan or Coupe models. For a ball mount I recommend # C45521 along with pin and clip # F-4. Then you simply need to add the hitch ball like # A-82 for a 2 inch option or # A-80 for a 1-7/8 inch diameter option. Then for your trailer wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55502. This custom-fit T-connector plugs into your...

  • The Curt Class I hitch # C11327 is a confirmed fit on the 2007 Honda Accord Sedan. It also fits the 2-door Coupe for model years 2003 through 2007. It will require some drilling and minor heat shield modification. I have linked an installation video as well as a helpful article to aid your hitch installation. In this hitch you can use Class I accessories like a 2-bike rack such as # S64670 or a cargo carrier like # C18145. If you plan to tow you'll also need a wiring harness # C55502...

You will need a kit specifically designed for flat towing. You can use a diode kit such as # 154-792-118158. You will also want to consult your vehicle owners manual on the proper procedure for towing the vehicle. If you need base plates on your 2006 Accord use # 1545-1 if it is not a Hybrid....

The connectors on the right side should be directly behind the trunk panels and trim that you have to pull out of the way just like on the drivers side. The Curt harness # C55502 only goes up to the 2012 Honda Accord.

  • Curt Trailer Hitch for a 2010 Acura TSX Sedan
  • There seems to be some sort of mix up because trailer hitch # C11085 is designed to fit the 2011 to 2014 Acura TSX Sport Wagon, not the sedan. The proper hitch for a 2010 Acura TSX sedan is # C11496. And it does appear to stick out a bit as you can see in the video I have linked. If you plan on doing some towing the correct ball mount is # C45521. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. For trailer wiring you can use # C55502.

Make sure you get power at the appropriate pin and that you aren't getting power on the others. You will want to inspect the 4-Way itself for any debris or corrosion that might be built up around and inside the pins, cleaning out as needed. Also try and inspect any wiring that...
