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.
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 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 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.
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.

Today, we're going to be taking a look at the currency connector vehicle wiring harness with the four pull flat trailer connector. This product fits certain models and years of the Kia Sorento. It's going to provide your four way flat trailer connector at the back of the vehicle to power your trailer signal lights. It is compatible with five pull, and six pull and seven pull adapters. Adapters are sold separately. And it's going to come with a dust cap for the four way flat connector, that way you can cover up the connection points when your plug's not being used.
The black box here, it's pre wired in. This is going to be your tail light converter. This is going to ensure that your vehicle's wiring matches that of your trailer. This module's going to connect directly to the battery through the wiring to avoid overloading the vehicle's electrical system. It's going to be constructed using surface mount technology, which is going to offer consistent, reliable performance.
The unit's going to connect quickly and easily.When it comes to installing it, all you have to do is locate the connection points behind your tail lights, then you're going to have two connectors. These are your t connectors. This side with the yellow wire's going to go to the driver's side of the vehicle. This side with the green wire's going to the passenger's side of your vehicle. So locate your connection points behind the tail lights, plug in your connectors.
The plugs are going to match up perfectly with the ports on the vehicle. It's a custom fit wiring harness, so they're going to snap together for nice, tight, secure fit. Once you get those connected, you'll need to make a ground connection. That's going to be your white wire with ring terminal attached to it. You want to get that grounded on a nice metal surface with the included grounding screw, and then you'll need to mount the converter box to a nice, clean, out of the way location using the provided double sided adhesive tape.
Once you have that done, you'll need to run your hot lead to the vehicle battery.That's going to be your black wire here. It's going to get connected to the bundle black wire with one of the included butt connectors. The other end of the black wire runs to the vehicle battery. It's going to get another butt connector attached to it, and it's going to connect to one half of the included fuse holder. The other half of the fuse holder gets a ring holder attached to it, and that's going to get connected to the positive post on the vehicle battery. It does come with your ten amp fuse. It goes right in fuse holder there, then you just close the cap to keep it safe and secure. Once you have all that done, you can go ahead and secure any excess or slack in the wiring with the included cable ties. Now, once your install is complete, the four way connectors are going to be set up beneath the vehicle, near the trailer hitch. We do recommend a mounting bracket to keep the connector secure. That's sold separately. You can find it here at etrailer.com.We also recommend that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the four pull connector itself, to help prevent corrosion to those connection points. That grease is sold separately. Also, and you can find that here. It's dielectric grease, but you can get it here at etrailer.com. Now when it comes to the maximum amperage for your stop and turn lights, we're looking at five amps per circuit, and for the tail lights, we're looking at five amps per circuit. The unit's also going to come with very detailed insulation and wiring instructions. It's going to walk you through the entire process step by step. That's going to do it for today's look at the currency connector vehicle wiring harness with the four pull flat trailer connector.

I gave this Curt wiring harness an excellent rating even though the initial one I received didn't work! That is because of the EXCELLENT customer service I received from Curt when I called. They offered to immediately send me a replacement at no charge, which arrived in two days. I put it in today and it's fine. Tomorrow I will call them as they asked me to and they will arrange with UPS to pick up the old one for analysis. How many companies do you know that would do this???? Most will tell you to pay to ship it back and when they receive the old one, they will send you a replacement in their own sweet time. Curt ranks #1 in my book for customer service and I would not consider buying from anyone else now! One thing to Sedona owners that isn't the fault of Curt. Don't think you're going to install this kit without a fish tape to rout the wires from inside the taillight area and down to the back of the bumper. It is IMPOSSIBLE without a tape or flexible wire. You also have to run a heavy gauge wire (supplied) from the engine compartment to the left tail light area to power the conversion box. Things are not as simple as in the old days of just spicing into existing wires. 74679
Everything worked great. Used a 4' long fiberglass rod to push up From the bottoming thru the left taillight attached the wiring of the rt taillight and pulled thru the small hole. Then passed the free end of pole up thru the right taillight and the hard part was done. Thank u Dana 71899

Relatively easy to install. Unlike other reviews, there was enough wire to get the passenger connection to the tail light. I roughted the green wire connection along the bumper. Having a wire fish tape helps get the wire connection into the tail light compartment. I ran the positive feed wire along side the rear drivers side brake lines. I had to drill a hole into the wheel well as there isn't any convenient features to wire tie the wire to. As discussed in other reviews, sticking the control module on to a flat surface is challenging as the compartment is tight. Take a clean rag and clean the surface as it will be pretty dirty. Also remember to put the tape on before you drop it in . I ended up attaching the ground to a flat area in the light compartment. There are no available ground stews. I sanded a small area and used the supplied self tapping screw and the coated it with dielectric grease. All in all, I am pleased with the product and the ease of install (although my wife still complained it took too long ) 31996

This item was priced fairly and was shipped with an upgraded shipping to express and arrived 3 days after order was placed. Very nice of etrailer to do that. This is a quality wiring harness with good instructions and wiring schematic drawing. Everything is included including tie straps. 129703
by: Amy O09/20/2013
It definately had to be connected to the battery which was a pain having to run the wires to the front of the car from the back of the car. I thought it was just as simple as plugging it into the connector in the tail light. 100734

I purchased the C56163 Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector for our 2011 Kia Sorento because of the price and because the information on the etrailer website was clear and easy to understand. I received the shipment well within the delivery time and all of the items were in the kit (harness, ties, connectors, fuze, etc.). Installation was very straightforward and matched the instructions provided with the kit. The most difficult thing to do with this installation was routing the wires under the vehicle because I do not have a lift and had to lay on the garage floor. I am very please with this purchase and recommend it for anyone who plans to install their own hitch and harness and wants to save $$$ doing it. 260559

I ordered the Curt hitch and wiring kit for my 2012 (4 cyl.) Kia Sorento. Mounting to the car went smoothly and wasn’t difficult thanks in part to watching the videos. I had a friend help which was nice, especially putting the hitch up in place. The products did just what they claimed to do and were cheaper than that other big orange and white place. I like how well Curt hides most of the hitch from view. A special treat was getting up graded to priority shipping (without my request) and receiving everything in about 2 ½ days. Win/win! 121334
by: George M.05/23/2015
Overall fit and finish is excellent. I installed the wiring kit on my 2011 Sorento. The instructions that come with the kit are basic. Watching the video on etrailers webpage explains everything perfectly. The one issue I did have is that the lenght of the cable from the T connector on the drivers side was not long enough to mount the relay box anywhere near where the video shows it. I ended up making the setup work, but it would have been much easier if the wires were a foot longer. Otherwise I am satisfied so far. 195220
by: Karol H.10/18/2016
I am pleased with the installation manual and overall outcome of the installation and performance. However, there are few things I would prefer an improvement, such as: - the yellow connectors are of poor quality and leave area where moisture can access and eventually cause issues. - the double sided tape does not work as intended, but the long zip-tie strap works well to keep the control box in place. - it would be nice if you would include a protective sleeve for the the exposed wires by the tow hitch. 308257

I had purchased and installed the product a year and a half ago Installed and worked at that time though never used after checking the installation. I went to use the trailer this weekend (both car and trailer in storage since installation) and the right light does not flash and the drive lights do not work at all. All works good on the car and checked with voltage tester There are leads that are hot at the connector with car not even on. Device - box must be shorted. 66697
It works okay for now. This is 3rd one I installed since May as first two failed after a few uses. The first one was covered and replaced for nothing. The first two were hard wired style. 3rd one is the new plug in style I only hope the new style ones are going to last. I would have thought curt would of replaced the second one also. I ended up playing for price for two. These were in installed on a 2013 KIA Sorento. 147958

This order was probably the best online ordering experience I've ever had. Within 1 hour of placing my order I received notification that my order had shipped!! ETrailer then upgraded my shipping to 3-5 day at no additional charge. I was shocked when UPS showed up the next day with my order! Great online buying experience! And I seldom ever write a review. Thanks Etrailer! Mark 9744
by: Rob S.05/30/2012
Easier than I expected. Plenty of wire. Ran the wire for the passenger side lights thru the brackets for the rear bumper. Running the black wire to the positive terminal of the battery was a little tricky. Ended up running it over the spare tire, there was a bracket there that I was able to secure it to. Then followed a break line run up to the engine compartment . 42017

I installed the hitch and the wiring harness this weekend on my 2011 Kia Sorrento. It took a total of about two hours – 90 minutes for wiring and 30 for the hitch itself. The directions were spot on and the job went exactly as described. This is the third hitch I have purchased from etrailer.com and have been very satisfied with all. Keep up the great work. 13108
The wiring harness was easy to attach. Everything I needed to get the 4-Way flat wire connector in place was included. I have ordered another wiring kit that will allow me to convert to 7-way RV connector with an electric brake controller. I'll soon be ready to tow my Aliner Sport pop-up trailer. 74508

This product is amazing. I recently had trailer wiring installed by Uhaul, and it did not work properly. Even though I purchased the 2yr wiring plan I decided against driving the 45 minutes to have them try and fix it for hours. I purchased this product and had it installed, tested, and completed in about 30 minutes. Everything works great. 97799
This product was fairly easy to install and worked like a charm the first time. The hardest part was running the wire from the converter to the battery. I actually ran it from the battery to the converter because it was easier to drop the wire down through a gap behind the engine. 89327
by: Dan D.09/01/2011
This was a time consuming project because of the difficulty routing the wiring through the limited access below the taillight housings. Overall it was not a hard project, just tough getting the wiring routed. They should mention that a fish tape would be needed to pull the wires. 23332

This product was fairly easy to install. The hardest part is routing the power wire from the taillights to the battery. The part takes about 20 minutes if the car isn't on a lift. Otherwise no problems! 133615
Perfect fit - easy to install if you don't mind doing a little bit of crawling around under the vehicle to run the power wire. FREAKY FAST DELIVERY! One of the best companies I've dealt with on the web! 26820
I just put in the trailer hitch and wiring harness which fit perfect. I am 70 years old and completed the job in about 4 hours by myself. Great product and good instructions. Thanks to all. 80883
