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. To locate this harness, you will have to pull back some of the trunk liner. 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.


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


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.

The installation went exactly according to plan, and the final install looks great. I used a mechanic's creeper and some ramps, which was extremely helpful. The videos on the website were excellent, showing every little detail. I cut an extra hole in the bumper for a 7-way connector, and I'm very happy with how it turned out.

I personally haven't ever seen someone add the hole to the bumper for the 7-way...it looks so clean! Thanks for sharing the photo and your genius!



by:

Instructions were easy to follow. The power wire that is needed ran to the battery. I put it in black split wire loom and hid it and secured it all the way to the battery. Everything looks good and works great.



by:

Shipping, excellent. Packaging was good, the boxing could use 3 reinforcing points. Instructions spot on. Receiver very easy to install. Wiring harness install a little more in-depth. Running the power/ hot wire from battery to receiver while laying on your back, watching for pinch points, chafing areas & exhaust & Ty wrapping is a 2 hr job. Receiver & harness 4 hours start to finish. Watch videos first, save yourself $[XX]-$[XX] dollars by doing a fairly simple install !



by:

The only improvement would be to include 2 weather proof heat shrink butt connectors in place of the 2 standard crimp butt connectors.



by:
2025 Kia Telluride

Worked great all wires were long enough to work. However an $80 wire harness could have included a fuse in the holder. Inconvenience after install have to go hunt down a fuse



by:

Great customer service!



by:

There were no install directions for my vehicle So it appeared not to fit. I talked to Bay at etrailer and he found out it could work but I had to take the rear door apart for it to work so I am returning for refund

This works good on a 2024 KIA Telluride EX with LED rear lights.



by:
2025 Kia Telluride

Instructions are spot on.



by:

While I have not installed it the connections all appear to be correct. Good instructions. I had an issue with delivery however but no fault of etrailer. The package went from Missouri to Indianapolis, then to Arizona, then back to Ohio then to me in Pennsylvania. Took extra 3 days to arrive.



by:

Easy to install. Watch the video and it guides you through every step including tips for the challenging parts. Thank you!

Easy installation. Works well



by:
2024 Kia Telluride

I viewed the video for the C29ZV and it was help full BUT in the video the control box that you run a wire to the battery to is on the driver side were there is all kinds of room were he zipe ties it to the factory harness but the C29ZV harness I got the control box is on the passenger side and you have to mount it above the muffler . that is stupid. All you have to do is make the green wire short and the yellow and brown long and it will work like it is in the video. CHUCK



by:
2024 Kia Telluride

Excellent video installs easily



by:
2024 Kia Telluride

Good, except the directions were backwards stating the green wire goes to the drivers side and the yellow wire to the right, but the yellow goes to the driver's side (left) and the green to the right.



by:

Wonderful product and easy to install.

  • How to Determine Correct Curt 4-Way Wiring Harness For 2024 Kia Telluride
    Yeah, it is definitely a bit to sort through, so I think we can help you out with the right 4-way wiring harness for your 2024 Kia Telluride. We'll start with the easy one, which is if you want to hardwire a 4-way, the model of your Telluride doesn't matter, and you can just go ahead and use the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. But this is the most challenging install, and something I personally don't recommend; it's just making things harder...

  • Where And How To Mount A 7-Way On A 2024 Hyundai Santa Fe
    Good question, Todd! I looked at some pictures we have of the Curt # C37RV hitch installed on a 2024 Hyundai Santa Fe and I think I found a good way to do it. Take a look at the picture I have included and you will see what I am thinking (circled in red). Mounting the # 18136 bracket to the bottom of the hitch should allow it to completely clear the bumper fascia, and it will come out far enough to allow easy access as well. From here, you will need to choose wiring if you haven't already....

  • Trailer Hitch and Wiring Recommendation for 2025 Hyundai Santa Fe
    Hey Eric, I am not seeing any other messages from you so I wonder if there was maybe a typo in your email address. But anyway for a hitch the etrailer part # e24ZV would be a great option for your 2025 Hyundai Santa Fe. Then for trailer wiring the Curt # C29ZV would work great too. I attached links below with current pricing as well.

    Hey Stephen, thanks for reaching out! For your setup I recommend picking up the etrailer Trailer Hitch Receiver # e45ZR and using the Curt T-Connector wiring kit for the basic 4-Way wiring. You'll need part # C93FV if you have an LX or S, OR the part # C29ZV if your 2025 Kia Telluride is a different model. To get you to the 7-Way, you'll need the Universal Wiring Kit # ETBC7. This gives you everything you need for a fully-functional 7-Way. You likely don't need a brake controller for...

  • Can a Brake Controller Adapter be Used on a 2024 Kia Telluride without the OEM Tow Package
    Hey Mario, thanks for reaching out! From what I'm seeing, it looks like your 2024 Telluride has that brake controller plug present whether you have the OEM tow package or not. According to our fitguide, the Curt Custom Wiring Adapter # C77BR can be used to connect your Curt brake controller to that OEM plug, but you'll still need the # ETBC7 kit - which means something in that OEM plug isn't connected. If you use a circuit tester you should be able to determine what pins in the OEM plug...

  • Trailer Hitch And 7-Way For 2025 Kia telluride EX X Line
    Hello Travis, thanks for reaching out. For your 2025 Kia Telluride EX X Line I recommend the etrailer Class 3 Hitch # e45ZR. This has a 2" receiver, and features the matte black coating you are looking for. We have found the matte black coating blends better with the underbody of the vehicle. For a wiring harness, you can use the Curt T-Connector # C29ZV. This is a 4-flat connector, and will work with your LED taillights. If you wish to upgrade that to a 4-flat/7-way combo, you can use...

    I'm not sure why they include that replacement latch but that is not required for any of the aftermarket hitches or wiring. It is probably something related to the installation of the OEM hitch. The etrailer # e45ZR you referenced is what I would recommend. This hitch has a bolt-on installation and a concealed cross tube for a nice clean look. It has a matte black finish and comes with a limited lifetime warranty. Since you have the EX you will need the Curt T-Connector Vehicle Wiring...

  • Trailer Wiring for Kia Telluride
    Hi Fred; the Curt T-Connector Vehicle Wiring Harness # C68JR is designed to fit the 2020 - 2022 Kia Telluride with Factory Tow Package. If you have the factory port for wiring you can still install the wiring harness without the tow package. Check underneath behind the rear wheel on the driver side to see if you have the connector. If you don't, you will need the # C29ZV you were looking at for a 4-way (assuming this is a 2023-2025) and then the # ETBC7 to upgrade to a 7-way. What year...

  • Why Should I Run the Trailer Power Wire Directly to My Battery Instead of a Vehicle Power Source?
    Hey Earl! The thought process behind running the Curt T-Connector # C29ZV wiring harness power wire up to the battery is so that your trailer lights won't be drawing power off of any circuits on your 2025 Hyundai Santa Fe. It offers an extra level of protection both for the circuits on your vehicle, and to ensure that your trailer lights won't go out due to too much power being drawn from any given circuit in your vehicle. We've had a handful of people ask this question in the past and...

  • Curt T-Connector Wiring Harness For A 2024 Kia Telluride SX X-PRO
    Hey Luis, The X-Pro is an SX so the Curt T-Connector Vehicle Wiring Harness # C29ZV would be a fit. The # C29ZV only excludes LX and S models. This harness would connect to your tail lights using similar connectors so it's a pretty easy install if you're wanting to do this yourself. If not, I've attached our installer locator below to help you find a shop. If you need anything else just let me know and I'd be happy to help.

  • Wiring Harness for 2024 Kia Telluride X-Line With LED Tail Lights
    Since your 2024 Telluride X-Line is not an LS or S model the correct wiring harness is the Curt # C29ZV. This will plug into the connection points in the rear cargo area and provide you with a 4-way to power your trailer's signal lights. The # C59236 you looked at fits all models but requires splicing so I do not recommend using this since you have a plug and play option available.
