CURT Custom Fit Vehicle Wiring - C99KR

  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

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.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. To access this harness you will have to remove the rear scuff panel and some interior trim.


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.


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.

The instructions could have had more good pictures to make it crystal clear for the install, but overall, I'm very pleased with how this works.



by:

Easy install. Good instructions. Used it to install on a 2021 Hyunda Kona.

No problems in the first year. Instructions on this were good. It has connected our little tear on a few trips.



by:

Overall, a great hitch that perform as needed for a 2022 Kona. Box arrived on-time, with some tears, but nothing missing. Installation was moderate effort; the fishwires were challenging, but once in place they worked. My Kona is FWD but I still had to drop the exhaust to get the right side of the hitch lined up. There was no model-specific wiring harness for the 22 Kona, so I used the generic CURT 56187 powered harness and positap connectors.



by:

Harness fit perfectly on a 2021 Kona EV. While the vehicle connectors were hard to reach, the Curt harness allowed me to wire for a trailer without damaging the factory wiring. I powered the converter box using a switched 12V circuit so there would be 0 current draw to cause battery drain while parked, an issue with EVs.



by:

This curt electrical kit was so easy to install. Less than 30 minutes. Direct plugs into the car electrical made this beyond simple. Love etrailers ability to line up products that are exact fit to whatever vehicle you have. Im on at least 8 hitches & wiring kits, and Etrailer delivered 100% on all….

the connectors in my car are 8 pin (orange color) and the harness that i received from etrailer.com is a 3 pin (blue color) I have asked customer service about this problem but not much help yet. While researching on the web i found that my car connector is called G11E8 (8-Pin Connector) and obviously it doesnt fit the 3 pin connector from the wiring harness i received

Of course making the right connections is important. I reached out to Curt and found that the G11E8 8 pin connector is typically the blind spot monitoring connector. The tail light connector is hard to get to. I recommend viewing the video installation that we have on a 2020 Hyundai Kona and look at time stamp 10:15. It is possible that the connector would not be blue however it would match the wiring harness connector to connect together.

Good product, easy to install. Your videos on YouTube are great.

Very easy ,plug and play

The wiring harness for my 2018 Kona is relatively easy to install. The video on the etrailer site explains of all of the components is professionally done. In the video she comments that the black and white photos on the instruction sheets are grainy and they definitely are . I suggest adding a link to a video actually going through an install. I found one on line and it clarified questions that I had about the taillight plugs . The video shows how to get easier access by removing several body pins to peel open the bumper corners instead of going up through the bottom .

It's always nice when you buy a product and it is the correct one the first time. I got this kit thinking it would be an all day event to figure out and instal. I was wrong! everything fit as it came. Nothing had to be modified or added. All in all, very easy to install on my 2021 Kona.



by:
2020 Hyundai Kona

My local shop said they couldn't get a harness for my car. And no class 3 hitch. So I found both on etrailer, and ordered both. I can't say enough good things about etrailer. My only complaint is that one place on the install video, the location of the clip to unhook wasn't very clear. I spent an hour trying to unhook the wrong clip. Found the location on a different youtube video. But otherwise, everything was great.



by:

This product does what it is supposed to. The problem is, it goes on a hyandai Kona, which is a horrible design. Put the light adapter on before you put the receiver hitch on.



by:

Great customer service ! Package arrived in perfect condition. Will buy again from this company no doubt !



by:

Good service from staff, but slow shipping with no tracking to schedule installation on car in advance. Ordered hitch from [online} as no stock at etrailer until February.
Helpful install video!



by:

When I received my original order there was some pieces missing. I called etrailer and they said they would ship it right out. I received the parts in two days!!!! They were very fast in getting them out to me. Very good customer service!! Thank you so much for your super fast delivery!!



by:
2020 Hyundai Kona

Easy plug and play. Watched a install video and fallowed the instructions, went together pretty easy. If you are putting the hitch on also do the wiring before the hitch it makes it easier to get to all the connections.

Went above and beyond!

  • Why Is There A Direct Line To The Battery If The Wire Harness Can Draw Power From The Tail Lights
    The extra wire in the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C99KR that you run to the battery powers the converter box so that it won't overload the tail light circuit and blow the fuse or cause the tail lights to dim.

  • Will Wiring Kit From 2021 Hyundai Kona Fit a 2022 Hyundai Kona
    The Curt T-Connector Vehicle Wiring Harness # C99KR that fits a 2021 Hyundai Kona will not fit the 2022 model. As of right now you'll need a universal-type wiring harness for the 2022 model. I recommend picking up either the Kit # C59496 which splices into your wiring or the Tekonsha ZCI Wiring Kit # 119250KIT which uses a specialized connector that prevents splicing into the factory wiring on your Kona. Both kits come with a power lead that runs to the battery on your Kona so the trailer...

    The best hitch for your 2021 Hyundai Kona is going to be the Draw-Tite Trailer Hitch item # DT52GR. This hitch is custom fit and bolts to your Hyundai with included hardware.

  • Hitch for 2021 Hyundai Kona to Tow Motorcycle Trailer
    For lighter duty vehicles like your 2021 Hyundai Kona there are only lighter duty 1-1/4 inch hitches available like the part # C11529 which do not have the weight capacity for a motorcycle carrier. With your tow vehicle best option would be a small trailer since the trailer axle carries the weight instead of the rear of the vehicle. For trailer wiring you'd then need the part # C99KR.
