Quickly and easily install a 4-way trailer connector on your Hyundai Sonata with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.
This custom-fit T-One connector plugs into your Hyundai Sonata's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the harness.
Once installation is complete, the 4-way flat connector will be stowed 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.
Circuit-Protected Tail Light Converter
A tail light converter is built into this T-One 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 Hyundai Sonata's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light 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 Hyundai Sonata operate.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

Today on our 2009 Hyundai Sonata, well be installing Tow Ready T1 Connector part number 118433. Well begin by opening the trunk. Now well need to remove the threshold and the fasteners for the interior to expose the wiring for our tail light. To remove the threshold molding, well simply reach under the trim with our trim tool, locate the tabs that are holding it in place and pop them free. Well now move on to the carpet covering the tail light wiring. Well need to pull the threshold molding away from the vehicle as there is a clip up here that holds the carpet in.
We can simply undo the clip then remove the pushpin clips from the vehicle which will allow us to fold the carpet down and away to expose the wiring. Now, our T1 connector will connect into the harness here at this white connector. Well simply unplug the connector. Well then take our T1 connector and plug it in line with the harness. Well also need to locate a point for our ground.
Now our vehicle has a stud and nut here located right next to the connector which will supply as a good ground for this product. And grounding the T1 connector, its always a good idea to find a non-painted surface to connect to. And with our ground secured, we can now take our converter box and find a suitable location and using the double-sided tape provided with the install kit, well expose the adhesive for the converter box and simply attach it to the vehicle. We can then tuck the wiring away and with our driver side complete, we can now move on to the passenger side. Well extend our red and green wire over towards the passenger side and well go ahead and follow the factory wiring harness routing.
There are included with the kit a few zip ties that we can use to attach it to the factory harness. Well just simply clip off the access. Now over here on our passenger side, well need to remove the carpeting cover again and with the passenger side harness exposed, well simply remove the connector and install our harness in line with the passenger side tail light. Well then pull our excess wiring back in behind the carpet giving us a nice fit when the interior carpet is reinstalled. Well now simply reinstall the carpeting and put our trunk opening molding back into place.
With the wiring installed, well go ahead and reassemble the interior components. Well now go ahead and show you how the harness works. Well simply unfold it from out of the trunk and lay it over the threshold here. We can then simply close the deck lid on the wiring harness as the molding will give enough that it will not damage the harness. You do wanna make sure that you stay away from the latch as the latch could damage the harness. And then simply bring it down to your trailer hitch and plug it in to your accessory. And that does it for the install of the Tow Ready T1 Connector part number 118433 on our 2009 Hyundai Sonata.

Video instructions made it look too easy. Actual installation was as easy as the video made it look! I've owned several Draw Tite hitches and this light duty hitch for my Hyundai Sonata was of the same high quality as my heavier duty hitches. 11352
YES YES! Absolutely use t-one connectors. They save SO much work and hide away when you're not using the plug. Makes the connection at the lights look factory. Well worth the money and VERY easy to install .. about 30 minutes to do it right.180

Easy to connect and worked exactly as described. Took about 10 minutes to complete. What a great product that fit exactly for my 2009 Sonata SE. So happy with this purchase and the parts are great quality. Shipping came fast with the receiver hitch and great packaging. You wont go wrong with this product.64744
The installation was very straight forward, following the instructions and viewing the video made it easy. The only change I made was to put the ground on a chassis ground near the tail light assembly rather than grounding it to the tail light assembly. 60821

After installing the hitch it was getting late but decided to have a look so I would be ready to install in the morning. Less than 10 minutes later the lighting kit was completely installed, the trim was reattached, and no wires were visible (they are tucked out of the way in the spare tire area). The video and written instructions were spot on.51574

Don't waste a minute of your time with a competitors product. Spend a couple more (or less) bucks to buy the perfect fit with etrailer. Compared to the "universal fit" that i started with, it's only a few dollars more but is installed sooooo much easier. It literally only took a couple of minutes to install this unit. etrailer's unit is less than half the price of comparable units I found from national auto part dealers. This is a great value and a great time saver. I highly recommend it!48414

I needed this harness, a hitch, some wire and connectors to get my car set up prior to its shipment to Germany. I was on a short timeline, as the car was to be shipped in 10 days after my order. etrailer knew none of this, but an hour after I placed my order on a Sunday, a CR rep emailed me to let me know the wire (not the harness) was not available to be shipped right away and that he was working on finding some in another warehouse. What company immediately get back with the customer to let them know there's an issue with their order? Not many, I can tell you. But because etrailer did this I was able to let them know my situation and they shipped out the rest of my order, which arrived in 3 days. Everything fits perfectly and was easy to install due to the extensive "how to" information on the site. Thanks etrailer, for making my buying experience a good one!41779

This wiring was really easy to install. I am not mechanically inclined and have never done anything like this before. On my 2007 Elantra, it was even easier than in the video. When I tested them out, everything worked just fine. The items were shipped the same day that I ordered them and arrived a few days later. Etrailer has made this a really easy experience for me.39826
Electrical installations and myself seldom get along. But this product coupled with the intsructions provided made it a snap putting this in my vehicle. I would recommend this product to anyone needing this type of installation on their vehicle.37810

Ordered hitch, wiring harness, and hitch draw bar for my 2010 Hyndai Elantra. The installation was so straight forward that it only took 20 minutes for the whole set up. I am very pleased with the product. Etrailer's service was exceptional.31963
by: Rob (Ohio)08/29/2011
Product was ordered in the morning and shipped same day. Arrived safe and FAST. Had several follow ups from the folks at Etrailer, It is quite possible I have found a comapny that remembers what it is to actually insure the customer is happy and satisfied.. I work for a Large Corp. , I see it has been forgotten in our own work and I see it at the places I service. Hurry in, get out, get paid. etrailer is doing it right !!! Rob 23083
