2012 Jeep Liberty - T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

Quickly and easily install a 4-way trailer connector on your Jeep Liberty with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.


  • Provides a 4-way flat trailer connector at the back of your Jeep Liberty 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 behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your Jeep Liberty's wiring matches that of your trailer
    • Powered module connects directly to the battery to avoid overloading Jeep Liberty's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn light: 2.1 amps per circuit
    • Tail lights: 5.6 amps per circuit
  • 1-Year limited warranty


This custom-fit T-One connector plugs into your Jeep Liberty'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.

Tail Light T Connector Diagram

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 and insert the provided fuse.

Once installation is complete, the 4-way flat connector will be stowed beneath your Jeep Liberty, 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.

ModuLite Powered Tail Light Converter

A ModuLite power module 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 Jeep Liberty's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine 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 Jeep Liberty operate.

With a ModuLite, your trailer's lights will be powered without overloading your Jeep Liberty's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Trailer Wiring Harness Installation - 2012 Jeep Liberty

Today on our 2012 Jeep Liberty well be installing the Tow Ready T1 connector, part number 118554. First to begin our installation well open up the rear cargo door. Well need to remove the fasteners that secure the taillight housing in place. Starting here on the drivers side, well go ahead and remove the two fasteners and then gently pry the taillight housing away from its current position, being careful not to break the alignment tabs underneath. Now well go ahead and remove the taillight assembly by pressing on the locking tab for the connector and removing it from the assembly. Well go ahead and set it aside for reinstallation later.

Next well go ahead and repeat the same process on the passengers side. Now well start making our connections. With the yellow and brown connector well take the socket and plug it into the connector on the drivers side, plugging in line with the manufacturers wiring. Then we can take the red and green wire connector along with our four pole and feed it down between the bumper cover and the body, and or sheet metal of the vehicle. Next well go ahead and attach the power wire for our converter box.

Using the black wire coming out of the converter, yellow butt connector provided with our install kit well go ahead and crimp the two together. Then well take the extra length of black wire provided with our install kit, strip back one end and install it into the butt connector and crimp it down. Now with that done well go ahead and take a clean cloth and clean off the sheet metal just below the taillight assembly. Once its cleaned we can peel back the two way adhesive and secure the converter box directly to the sheet metal. Now well go ahead and take our power wire and follow the same route as our red and green wire connector and four pole down between the bumper cover and the body of the vehicle.

Next well go ahead and take the white wire with the preattached ring terminal which will be the ground wire for our converter box, and secure it to the body of the vehicle, using a self-tapping screw. Locating an area where the sheet metal doubles up can make for a great ground location. Now with the ground secured, well go ahead and take our taillight assembly and lug it into the opposite connector of our new Tow Ready harness. Now we can go ahead and reinstall the taillight assembly. Now with the drivers side reinstalled well go ahead and get underneath the vehicle and start routing our wires over to the passeners side.

Keep in mind when routing your wires you want to stay away from excessive heat, such as the exhaust, or moving components such as steering or suspension. As we route the red and green wire connector along with our four pole that will go to the center of the vehicle and down to the hitch, as were routing them along well use zip ties to secure it up underneath the vehicle. Now that weve got our red and green wire connector over on the passengers side well go ahead and feed it up behind the bumper cover and the body of the vehicle below the taillight assembly. Now with our wire secured underneath well go ahead and cut off the excess from the zip ties to clean up our install look and move back to the passengers taillight assembly. Here well go ahead and take the red and green wire and zip tie or secure it to the manufacturers wiring. Then we can make our connection with the T connector and the manufactures wiring. Now for our extra wire well go ahead and bundle it up and use a zip tie to secure it, and then take the socket and plug it into the back of the taillight assembly. With that done well go ahead and reinstall the taillight assembly. Next well get back underneath the vehicle and start routing the power wire up to the front of the vehicle into the engine compartment and up to the battery. As we route our wire well go through the frame when possible and zip tie as necessary. When routing through the frame well use a pull wire, or in this case well be using a piece of air tubing to assist in routing our wire. Now that weve got the wire routed up toward the front of the vehicle well need to add a couple of loom clamps to assist in securing our wire. Well be using the Redline metal loom clamp, part number A0500 along with a couple self-tapping screws. Now that weve gone through the second loom clamp well go ahead and feed it up into the engine bay, and then pull it up to the top of the engine compartment. Here we can take a zip tie and secure it, and then route it over to the battery. Now well go ahead and remove the battery cover and prepare our fuse holder. In this application when preparing our fuse holder, well go ahead and cut the fuse holder off center to leave enough length so that we can travel up through the positive battery terminal cover. After we cut it, well go ahead and strip back both sides and on the short side well add the yellow butt connector and secure it. The long side well feed up through the battery cover and then secure our ring terminal to it. Now that weve got the ring terminal secured well go ahead and remove the nut on the positive battery post, install the ring terminal and then resecure the nut. Now well go ahead and finish routing the fuse holder and reinstall the positive battery cover. Next well take our fuse holder and the black power wire and cut off any excess from the power wire. Then well strip it back and attach it to the yellow butt connector. Once weve made this connection well once again go ahead and wrap up the yellow butt connector and wire with some black electrical tape. With that done well go ahead and install the fuse and the fuse cap. This will complete the install of our Tow Ready T1 connector, part number 118554 on our 2012 Jeep Liberty.

Owning a few landscaping and irrigation companies in the past, I've always had guys that knew what they were doing when it came to this stuff. However, not this time. I looked up the parts and decided to call so that I'd be certain to get the right setup for what I needed. Out of the package I had no problems following the clear and concise instructions to completion. Plugged in my trailer, checked the lights...good. Camper battery and D.C. fridge operation while plugged in to harness...good. Went for a drive to test breaks with some minor adjustments as the instructions eluded to being necessary...all good. Very satisfied and would order again in a heart beat. Thank you for your excellent products and respective instructions. 360674

The installation video found on your site couldn't of been any better! I ordered the curt hitch and Tone wiring harness for my 2012 liberty, delivery was fast and installed hitch in 10 min in my garage! 83751


Product is great except after towing 1 time now my passenger side rear turn signal will not work with the T-one wiring harness plugged in to that side, at first I thought it was a blown bulb , found bulb was good after I unhooked the rear passenger side t-one harness and plugged factory plug back in , the bulb is good, do I need to install a heavy flash relay? Or module? Help!!

-- comment by: Glenn - 06/13/2013


Check the individual pins in the plugs on the harness and the plugs for the taillights of the vehicle, make sure they are seated all the way in. We saw this happen on another Dodge vehicle and had the exact same symptoms. If that does not solve it for you, there are some diagnosing procedures we can walk you through. Just give us a call at 1-800-298-8924.

I hooked it up by myself just fine. Not clear on which directions to follow. The paper directions says to disconnect the negative battery, the online doesn't. I disconnected my battery on a 2008 Jeep Liberty and now I am having computer problems that the dealership cannot figure out. It says "error" on the odometer and might cost me a pretty penny. Very unhappy about that. 41089

by: Aaron H.05/24/2012

Wow! This thing is awesome. Not only was it easy, it looks like a factory installed harness. There are no cobbled wires or nasty splices anywhere. Love it. The installation videos on this site make etrailer the best! I hate hard to follow goofy written instructions. P.S. If it had little shrink tubing for the battery wire splice that would have been even better. 41541

by: Larry02/26/2017

The product worked great. The only suggestion I would have is the driver side in line connection should be two inches longer, where it plugs into the actual tail light. This would make it easier to fold into the area where the wires fit better. I would recommend this product. I do not have pictures but other than what I said very easy to work with . 346098

this wiring harness was easy to install and is working just fine after a year on the road. I did have to run an extra wire to the brake light at the rear because the brake light did not work as per instructions said it would because of the way the jeep is wired. My was different then the earlier ones. etrailer is the best place to buy. 289940

Installed this on my 2008 Jeep Liberty Sport. It was very easy to install and of good quality. The only thing I changed was, I used a couple heat shrink connectors instead of the ones that came with it to help a little bit better against moisture and corrosion. Overall, I am very happy with my purchase 256848

Wiring harness was quick and simple plug-in at the rear tailights but the most challenging was running the power line from the rear of the 2010 Jeep Liberty to the engine compartment. It took a little longer than I expected. All parts needed were in the kit for installation. 86552

The hardest part of wiring the light was getting the wire to the positive post of the battery. All together it took me about 3.5 hrs, I did it by myself. Other than that, everything works fine. I am very pleased with the result. All lights on my Jeep and trailer work. 171417

  • Recommended Weight Distribution System for 2012 Jeep Liberty for Towing Small Camper
  • As a general rule of thumb, anytime the trailer you are towing weighs more than half the weight of the vehicle towing it, a weight distribution system is recommended. Since the curb weight (weight of vehicle not including cargo or passengers) of your Liberty is about 4000 lbs, a weight distribution system is definitely called for. The relatively short wheelbase of the Liberty will make the trailer more susceptible to trailer sway, so going with a weight distribution system that also...

Part # 118381 would plug inline with the wiring harness leading to the 7-way. Since you do not have the factory hitch, you probably do not have the tow package and would want to use part # 118554. Installation is pretty simple. Access the rear of the tail light assemblies, plug the connectors inline with the existing connections behind the tail lights, and run the power...

  • For a complete towing setup for your 2010 Dodge Nitro Heat to pull your 21 foot travel trailer, you will need a hitch, brake controller, and wiring. In addition, I would recommend a weight distribution system with sway control, and adding an aftermarket transmission cooler. The Draw-Tite Trailer Hitch, part # 75517, which is a Class III 2 Inch Hitch, would be a good choice for your Dodge Nitro. Part # 75517 mounts below the rear bumper fascia. We do not have a hitch available for the...

  • Trailer Hitch Recommendation for a 2011 Jeep Liberty
  • You may not believe this but even the Class II trailer hitches for a 2011 Jeep Liberty have the face of the receiver extend beyond the rear bumper of the vehicle. Since this is the case, I would go ahead with a Class III. If you are going to have bruised shins, might as well be from a hitch with a higher capacity and more accessory options. For a Class III hitch I recommend the Draw-Tite Trailer Hitch, # 75578. I have included a link to the installation instructions. In the upper left...

  • Trailer Hitch, Wiring, and Brake Controller Recommendations for a 2008 Jeep Liberty
  • If installed correctly the Tow Ready T-One Wiring Harness for the 2008 Liberty by Jeep, part # 118554, you should not have to worry about damaging the electronics. This converter only uses the vehicles signal inputs as switches, and the actual power output to the trailer comes directly from the vehicle battery. The converter is designed to only draw 5 mili-amps and is designed to protect your vehicles sensitive circuitry. I've included installation directions in a link below. We offer...

  • Installing 7-Way Trailer Connector on 2009 Jeep Liberty
  • You're on the right track. You'd first need to install a T-1 connector like part # 118554, which will provide a 4-pole connector for the trailer lighting functions. To convert to a 7-way connector, you'd use the # 37185 adapter, which will plug into the 4-pole provided by the 118554 and provide you with both a 4-pole and a 7-way trailer connector. This is the way you'll want to go if your trailer is NOT equipped with electric brakes. However, if your trailer has electric brakes, and...

  • Recommended WD System and Brake Controller for 2010 Dodge Nitro to Tow Horse Trailer
  • For a weight distribution system to tow your horse trailer you will want a system that has a tongue weight capacity range that encompasses the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the vehicle. A trailer's tongue weight rating is usually between 10 and 15 percent of the trailer weight; if the tongue weight of the trailer when ready to tow is between 350 and 525 pounds and you are not carrying any additional cargo...

  • Comparing Trailer Hitches for a 2010 Dodge Nitro
  • I spoke with my contact at Curt regarding Trailer Hitch, # 13334, and he stated that the hitch design is comparable to there other higher capacity hitches but the engineers that designed the hitch decided to rate it at 3,500 pounds, 5,000 pounds when using weight distribution. From the research I did, your 2010 Dodge Nitro has a maximum towing capacity of 5,000 pounds. Based on the weight capacity rating of the Curt hitch, it can reach that amount but you would need to use weight distribution...

  • Yes, Curt hitch # 13245 is designed to fit around the under vehicle spare tire on 2009 Jeep Liberty 4x4 models. The installation is very straight forward as well, as you can see at the link to the installation instructions I have provided.

  • Which Trailer Connector Will Fit T-One Vehicle Wiring Harness 118554 on a 2010 Jeep Liberty
  • Once the 118554 harness is connected to your 2010 Jeep Liberty it will connect to any trailer with a flat four pole harness. If you need a flat four pole harness for your trailer we do have one available. You could use part # 18044 and cut off the vehicle side connector since you do not need it and attach the other end to the wires on the trailer. If your trailer has a different style connector, like a 5/6/7-Way connector, let us know and we can find you the other parts you would need.

  • Is A Trailer Hitch Available For 2011 Jeep Liberty That Only Receiver Is Visible
  • All of the trailer hitches we offer for your 2011 Liberty have the receiver located in the middle of the crossmember of the hitch. Some hitches actually have the receiver welded to the bottom of the crossmember and that does hide a lot of the hitch but not the receiver as you mentioned. The trailer hitch I recommend for your Liberty is the Draw-Tite Max-Frame Trailer Hitch, part # 75578. This is a Class lll trailer hitch with a 2-inch receiver opening. If you plan on doing some...

  • Which Trailer Wiring Harness Should I Get for my 2008 Jeep Liberty, # 118554 or # 118381
  • Both the Tow Ready Custom Fit Vehicle Wiring for the 2008 Liberty by Jeep, part # 118381, and the Draw-Tite Custom Fit Vehicle Wiring for the 2008 Liberty by Jeep, part # 118554, will work on a 2008 Jeep Liberty. The difference is that the #118554 is used on vehicles that do not have a tow package, and the #118381 is for Libertys that have a factory 7 way and want a way to have a 4 way connector as well. If your Jeep Liberty does not have a tow package you will want to use the # 118554...

  • Testing the Running Light Circuit on a 4 Pole Trailer Connector
  • If you are not sure of the exact wiring harness you are using on your 2012 Jeep Liberty, then you could be using a wiring harness that is not compatible with your new jeep. The T-One Vehicle Wiring Harness, part # 118554 is the correct wiring harness for your vehicle. If you verified that you have the correct wiring harness, then it sounds like the converter box could have a short allowing constant power to run through the running light circuit, or the brown wire on the wiring harness...

  • Recommended Trailer Hitch And Wiring For 2010 Jeep Liberty

  • Recommended Hitch, Trailer Wiring and Brake Controller for 2008 Jeep Liberty
  • If the available hitch alternatives for your Liberty, I'd recommend the Curt Class III hitch, part # 13245. All the Class III hitches for you Liberty have the same capacity and would install in the same manner. Because the quality of the Curt hitch is on the same level as the other hitches, you won't sacrifice anything by going with the lower cost Curt hitch. For trailer wiring, I'd recommend the Tow Ready # 118554, which would provide a 4-pole trailer connector. This will provide you...

  • Will Curt Trailer Hitch # 13245 Fit a 2012 Jeep Liberty with an 18 Inch Full Size Spare Tire
  • I spoke with my contact at Curt and he stated that as long as the 18 inch spare tire on your 2012 Jeep Liberty is a factory spare then trailer hitch # 13245 will fit around it. I have linked instructions and a video for you to view. If you plan on doing some towing I recommend the etrailer ball mount kit, # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag. For trailer wiring use # 118554. I have linked instructions and a video for it as well.

  • No Power On Trailer Wiring Harness Installed on a 2012 Jeep Liberty
  • To determine if wiring harness # 118554 is the problem, you will want to test it. With the trailer disconnected you will need to use a circuit tester such as # 3808 to test the pins on the 4-Way end of the wiring harness while someone sits in the 2012 Liberty and runs through each light function. If there is no power on the harness at the 4-Way then you can make sure that 1) the fuse is installed in the power wire, 2) the power wire is connected to the positive battery terminal, 3) the...

  • Can a Trailer Battery be Charged through the Trailer Connector on a 2011 Jeep Liberty
  • A trailer battery cannot be charged with trailer connector wiring because the wiring is too small and the vehicle alternator cannot provide the amperage to up charge a trailer battery. At best, it can only maintain the current charge that is in the battery. To charge a trailer battery, I recommend a battery charger like # CTEK56158. This charger is much more effective than old school trickle chargers and it will not overcharge a battery. The charger uses a 4 step process to charge a...

  • Diagnosing Ground Problem on Trailer Towed by 2008 Jeep Liberty
  • You are describing one of the classic symptoms of an insufficient ground connection. When you turn on the vehicle headlights and the running lights on the trailer come on, the system is pulling maximum amperage. If there is poor ground connection, this is when it will show itself. Make sure that the ground wire for the trailer connector on your Liberty is securely attached to clean metal on the vehicle chassis or frame. Check the connector on the trailer. The white wire from the trailer...

  • Do I Have to Run a Power Wire to Front of 2009 Jeep Liberty When Installing 4 Way Trailer Connector
  • For your 2009 Jeep Liberty we offer the Curt T-Connector Vehicle Wiring Harness, # C56183, as well as the Tow Ready Custom Fit T-One Vehicle Wiring Harness, # 118554. Both harnesses require running the black wire to the vehicle's battery. In testing, both Curt and Tow Ready have found that the taillights alone on the 2009 Liberty can not support the electrical draw from trailer lights. This is why the black wire must be run to the vehicle battery. With the black wire run to the battery,...
