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.

    • Plug in T-connector

  • Constructed using surface-mount technology (SMT) for consistent, reliable 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 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.


Once installation is complete, the 4-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 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.

Ordered, this kit along with towing package for my son's '22 Tacoma, everything fit and performed as it was advertised.

2016 Toyota Tacoma

Ironically, this is the second time I’ve purchased C56349 for my 2016 Toyota Tacoma. Both times I installed this product, it was extremely easy. The installation instructions are fantastic. I unfortunately had to buy this product a second time because the RV dealer where I purchased my camper cut into the circuit board wiring for no apparent reason. FYI, Curt does not issue the wire diagram for the circuit board, which I understand. Happy that I got this product 2x for a great price!

The video and instructions were so helpful and well done. Your website was easy to use.

2016 Toyota Tacoma

This product is totally worth the money!!!! Everything worked the first time .. the install was very easy, only thing that was a little difficult was running the positive cable from the battery to the rear bumber.. just take your time and follow the chassis, that was a big help.. I bought this product to install rear led brake light strip and wanted to hide the cables to give it a oem look.. would definitely recommend this product!



by:

Relatively easy install. Make sure you watch videos on the process. No issues since.

Easy to install. Long lasting, I had it installed for 7 years. I had to replace the unit after I was rear ended and the unit wad damaged.



by:
2017 Toyota Tacoma

Does its job, very simple, longest part is running wires and securing with zip ties. Works great! If you watch the video on Etrailer from the older model you get a good idea of how it all goes together it’s only slightly different.

Wiring worked great and this company provided tech support when I needed it. I recommend them!

  • Right Turn Signal/Brake Light Stays On with Curt Trailer Wiring Harness on a 2016 Toyota Tacoma
    What you are describing sounds like a short in the converter box for Curt wiring harness # C56349 for your 2016 Toyota Tacoma. Since this is the second time this has happened it could indicate that there is something on the trailer that is causing the box to short out so I do recommend inspecting the trailer wiring and fixing any broken or pinched wires or anything else that seems problematic. I also recommend switching to the Curt harness, # C56349, because we hear about less problems...

  • Are the Trailer Wiring Harnesses the Same for Both a 2017 and 2018 Toyota Tacoma
    If you are referring to a trailer wiring harness then no, the trailer wiring harness for a 2017 and 2018 Toyota Tacoma will be the same. For this, I recommend using the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56349. This harness is a direct plug and play option that will give you a 4-way trailer connector at the rear of the vehicle without requiring you to cut or splice any wires.

  • Would Trailer Wiring Cause Vehicle Blinkers to Hyperflash
    Trailer wiring should not cause hyperflashing on vehicle taillights. It would be related to the LED taillights you installed on your trailer. Most likely the resistors on the new lights aren't the correct value. You can test this by going back to the standard taillights and leaving the trailer wiring installed.

  • Is Running The Power Wire For the Curt T-Connector Vehicle Wiring Harness # C56349 Required?
    Yes, the power wire for the Curt T-Connector Vehicle Wiring Harness # C56349 must still be ran to the battery on your 2019 Toyota Tacoma SR. The power wire for this is where the converter gets the power it is sending to the trailer lights. This prevents excessive draw on your factory wiring and damage to the factory harness.

    The wiring harness confirmed to fit your 2017 Toyota Tacoma requires a battery line being added. This is really to protect your wiring system. The powered converter reduces strain on a factory system and protects the system. I know it seems like more work to add a power line to the battery, because it is more work, however the work will give you peace of mind knowing that your converter will function correctly and keep your factory wiring from malfunction which isn't always easy to fix.

  • Recommended Trailer Wiring For 2020 Toyota Tacoma
    I recommend the Curt T-Conenctor Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56349 for the 2020 Toyota Tacoma which plugs in behind the tail lights so there is no need for a tow package on the vehicle. The black wire does need to be extended to the Tacoma's battery to power the converter. This will give you a 4-pole flat at the rear of your vehicle to power the trailer lights. The Tekonsha brand wiring has proven to be more reliable and durable than the other brands...

    The Plug-N-Tow (R) Short Proof Powered Taillight Converter - Heavy Duty # 46365 can be used on your 2017 Toyota Tacoma and will work fine. However, I recommend a wiring harness that makes installation easier and doesn't require splicing that also draws power from the battery to protect your vehicle's electrical components.

  • Why Would Trailer Wiring Harness Cause Taillight of Vehicle to Stay On
    The converter box of the wiring harness shorted out and is now causing the problem you described. Only solution is a new kit as the box is not replaceable or repairable. The current kit for your 2016 Toyota Tacoma is the # C56349.

  • Troubleshooting Wiring Harness Connections on 2018 Toyota Tacoma
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56349 is the confirmed fit for a 2018 Toyota Tacoma. The adapter on a US vehicle will give you an adapter that will reach each side correctly. There should be a connection on each side of the vehicle as shown in the attached video. You will need to make sure the connections are made on the correct side as they cannot be reversed for proper connection and function.

  • Do I Need a 4-Way or 7-Way Trailer Connector for a 2020 Toyota Tacoma
    In regards to trailer wiring harnesses, there are two main types, 4-way and 7-way. The 4-way is used on smaller trailers without electric brakes and the 7-way is used on larger trailers with electric brakes. The trailer brakes won't work unless you have a brake controller hooked up in the tow vehicle but you can still tow the trailer without it no problem so long as you have the right connector. It sounds like you might have a 2020 Toyota Tacoma and in which case, the Curt T-Connector Vehicle...

  • Does Converter Need to be Used to Match Truck Wiring to Trailer Wiring
    That all depends on if your trailer lights have the stop light circuit combined with the turn signals or not. If the stop light and turn signals are combined then you should be good to go but if they are separate you will need to install a converter like part # 118158 to separate the stop and turn signals and match your trailer.

  • Does Standard Trailer Wiring for 2019 Toyota Tacoma Require Running Battery Wire

For a long term solution a trailer wiring kit like the Curt T-Connector part # C56349 would be your best solution since you wouldn't have to worry about batteries dying or the magnetic lights getting lost, but this will require running the battery wire like you mentioned.
