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.
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.

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!

Always loved the plug and play connections, the hardest part of the job was running the power line to the battery.

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!

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!

view full answer... - Right Turn Signal/Brake Light Stays On with Curt Trailer Wiring Harness on a 2016 Toyota TacomaWhat 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...
view full answer... - Are the Trailer Wiring Harnesses the Same for Both a 2017 and 2018 Toyota TacomaIf 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. I have attached an install video this harness on a similar 2016...

If you are looking for a 4-way trailer wiring harness to tow a trailer, then I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56349. If you are looking for a 7-way trailer wiring harness to tow a trailer with brakes, then I recommend the Tekonsha OEM Replacement Vehicle Wiring Harness with Brake Controller Adapter part # 22117. I have also attached an install video of the 4-way...
view full answer... - Would Trailer Wiring Cause Vehicle Blinkers to HyperflashTrailer 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.
view full answer... - 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.

It intended for trucks without the factory tow package. Please note that the term 'tow package' does not always mean the same thing. What is included in a 'tow package' can vary considerably from auto maker to auto maker, between models and even between model years. In our experience a Tacoma will either have a complete wiring set-up with wiring and trailer connector...

I've liked to an installation video that you might find helpful.
view full answer... - Recommended Wiring Harness For 2017 Toyota TacomaThe 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.

view full answer... - Recommended Trailer Wiring For 2020 Toyota TacomaI 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...

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. I recommend the Curt T-Connector # C56349. This harness plugs into your factory wiring already present behind the tail lights with quick connects and then a hot lead...
view full answer... - Why Would Trailer Wiring Harness Cause Taillight of Vehicle to Stay OnThe 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.
view full answer... - Troubleshooting Wiring Harness Connections on 2018 Toyota TacomaThe 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.
view full answer... - Do I Need a 4-Way or 7-Way Trailer Connector for a 2020 Toyota TacomaIn 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...
view full answer... - Does Tekonsha Trailer Wiring Kit # C56349 Fit 2019 Toyota Tacoma 4 CylinderYes, the Curt 4-way part # C56349 that you referenced does fit your 2019 Toyota Tacoma 4 cylinder as it fits all models of the Tacoma.
view full answer... - Highest-Rated Trailer Hitch Receiver For 2023 Toyota TacomaThe highest-rated trailer hitch receiver for your 2023 Toyota Tacoma is a Class IV hitch with a 7,000 lb towing/1,050 lb tongue weight capacity and is made by Draw-Tite. The part number you need is the following: - Draw-Tite Max-Frame Trailer Hitch Receiver # 75238 Since it sounds like you are going to be using the # 75238 for some towing, if you also need a 4-way wiring harness the right fit for your truck is the T-Connector Vehicle Wiring Harness # C56349.
view full answer... - Does Converter Need to be Used to Match Truck Wiring to Trailer WiringThat 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.

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. I attached an install...
view full answer... - Constant Power On Curt Harness for 2019 Toyota TacomaIf there is constant power on the trailer connector at any of the circuits while the vehicle is off, then this indicates the converter has gone bad and the entire wiring harness will need to be replaced.

What will happen is the converter box will short itself out as a way prevent the short from making it to the vehicle wiring. Bad part is that it permanently damages the converter and requires it to be replaced, but at least your vehicle will be protected.
