Tekonsha Custom Fit Vehicle Wiring - 118524

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


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 behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite 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 of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 4.2 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One 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.


T-One Connection Location Points Behind Tail Lights

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 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.


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 vehicle'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 vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle'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 - 2006 Jeep Liberty

Today on our 2005 Jeep liberty well be installing the Tow Ready T1 connector part #: 118524. Our first step, well need to open up the rear cargo door. This will allow us to access the two fasteners on each side securing the taillight assemblies. Starting here on the passenger side well go ahead and remove the two fasteners and then the taillight assembly. Be careful when prying the taillight assembly away from the body of the vehicle not to break the alignment tabs as you can see here. Next well go ahead and remove the manufacturers wiring from the taillight assembly.

First using the leverage of a flat bladed screwdriver well go ahead and unlock the red locking tab. Then pressing on the connector lock remove it from the taillight assembly. Now well go ahead and move over to the driver side and repeat the same process of removing the two fasteners and then the wiring connector. You can also remove the wire hold down and go ahead and set the taillight assembly aside as were going to do here. Now were ready to go ahead and start making connections with our new T1 connector.

Taking the brown and yellow wire were going to feed it up from underneath the vehicle between the bumper cover and the sheet metal of the vehicle. This will allow us to put it up behind the driver side taillight assembly and go ahead and make connection with the manufacturers wire. Now we can go ahead and get underneath the vehicle and start routing our wires. With our wiring underneath the vehicle well go ahead and take the black wire provided with the install kit, that will be our wire fed from our battery to our converter box. Using the Yellow but connector supplied with the install kit we can go ahead and strip back both the red wire from the converter box and the black wire from our install kit and use the but connector to connect the two.

Next, we need to mount our converter box. To do this well peal back the cover of the two sided adhesive and adhere it to a clean flat piece of sheet metal. Up behind the bumper cover against the body of the vehicle is a flat piece of sheet metal we can adhere to. Now with that done well go ahead and take our white wire with the preformed ring terminal, run it over to the frame using a self-tapping screw provided with our install kit and secure it for our ground. Now were ready to go ahead and start routing our wires.

When routing your wires youll need to be mindful of excessive heat such as the exhaust or moving components such as the steering or suspension. Well go ahead and take four pole over to the center of the vehicle down to the hitch and our green wire well follow the four pole over the top of the hitch to the passenger side up behind the passenger side taillight assembly just as we did here on the driver side. Next well go ahead and take some longer black zip ties and secure the wires to the hitch. Now to clean up my install look Ill go ahead and take a pair of side cutters and cut off the excess from the zip ties. Next we need to start routing our black power wire to the engine compartment. To do this were going to use a piece of pull wire to rout our power wire through the frame. For this application Ill be using a piece of air tube or airline. You can also use a stiff piece of wire, it works just as well. Now that Ive routed through the frame as far as I can go Im going to add a wire loom here to run my wire too away from the exhaust and then up into the engine compartment. Now were ready to go ahead and pull our power wire up into the engine compartment. Again, well be using our black zip ties to secure our wire as we rout it over to the positive battery terminal. Next well go ahead and cut off the excess wire as we need to add our fuse holder. To prepare our fuse holder well go ahead and cut it half, stripping back both sides and the end of our power wire. Now we can go ahead and add a ring terminal to one side and the but connector to the other. Then well take the other end of our but connector and patch it to our black power wire. Once again, Ill go ahead and use some black electric tape to wrap up this connection point. Now we can go ahead and rout the fuse holder over to the positive battery terminal and make our connection. With that done well go ahead and take a couple of black zip ties to secure our fuse holder to the manufacturers wiring. To clean up my install look once again Ill go ahead and clip off the excess from my zip ties. Now were ready to go ahead and install our fuse into the fuse holder. Well be using the blue 15 Amp fuse provided with our install kit. With that done we can go ahead and put the cap on our fuse holder and this will complete the installation of our Tow Ready T1 connector part #: 118524 on our 2006 Jeep Liberty.

Has worked perfectly on my 2007 JEEP Liberty, hooks up to the standard trailer plug and works great. Made 4 trips with a trailer in tow, absolutely perfect function for lights. Installation was a breeze, I watched a few install videos. I did a few more steps than one would expect, mostly to secure the module into the chassis cavity of the left rear light cluster, and the B+ BLACK wire connected to the yellow fuse clip, and then the car battery POS terminal. The mounting bracket was attached to the chassis with the included screws, BUT I drilled and then tapped the holes (were they 8-32 or 10-32 ? ) to screw the bolts directly into the chassis. Gooped the bolts with a gel lithium grease for rust protection when I screwed them into the chassis metal. Suggections! Please replace the black B+ positive wire with a RED color insulation wire, to maintain correlation with standard DC color coding for wiring. Add a good 12-14AWG yellow jacket butt splice to the kit for the BLACK B+ positive wire to the YELLOW fuse clip wire. I had to use one of my own stock, the butt splice you sent would not accept the 12 gauge wire. Thanks guys! Highly recommend this kit for a 2007 JEEP Liberty. 664932

Works great on my 2003 Jeep Liberty. Installation was very easy - other than running the power wire through the frame to the battery. The posted video was very helpful in figuring out the routing for that wire. This was my first etrailer.com order and I am incredibly impressed by how complete and helpful the site has been - thanks! 202883

The product fits and works as advertised. Install too about 3 hours. 15-20 minutes for the harness connections and wire routing at rear of my 2005 Jeep Liberty and the rest of the time spent routing and securing the battery wire. That was the hardest part of the install. 193568

I purchased a trailer hitch for a Jeep Liberty about 18 months ago. Installation was simple with the instructions provided with the hardware and the videos on this site. I would encourage others to heed their warning that corrosion and rust should be removed from the holes on the vehicle before installing a hitch. Anyway, not only did the site contribute to simple installation, but their customer service was excellent. I received my hitch sooner than expected, which was beneficial because I needed to use it quickly. The whole system has been working great for this entire time. I have no complaints and will continue to use this site. 88537

Hitch and wiring was ordered on Monday am, was at my door Wednesday 6pm. Very easy installation, good product. My only problem was that the bolts supplied with the hitch did not fit my Jeep. I had to go to the local hardware and buy 6 grade 8 bolts in the proper size, at 79 cents apiece. I cleaned the nuts with a tap, still the provided bolts would not fit, but the ones from the hardware screwed right in. I did read the reviews on your site for this hitch, others have had the same problem. That said, I would do business with e-trailer again. 85885

Very satisfied with the product and the service. Installation was very close to the video instructions. The only thing keeping this from getting the highest mark: the wire loom and self tapping screw called for in the installation instructions for the black power wire were not included in the package, that required a trip to the store. 84913

It seems bizarre that you write a review about somebody doing exactly what they said they would do for you. Well, my experience has been horrible with customer service in the last 5 years. Then along comes e-trailer. I ordered the part and it shipped the same day. I had a confirmation email letting me know what part was on the way along with the tracking info. I had an email letting me know it was delivered to my house. Installation was a snap with best directions I have used in a long time. This was a great experience and it was handled with best customer service experience in years. Thank you e-trailer. 51088

Plugged right in! Couple quirks, needed a Torex 20 screwdriver and used more zip ties than what was included. Also, tried stuffing the control unit into the bumper area before I realized I could just stick it to the light housing itself. Much easier. Net took about 1.5 hours and most of that was crawling under the jeep routing the power line up to the battery. Easy.... 50411

Do you have a question about this Custom Fit Vehicle Wiring?


  • How Do You Determine If a 2006 Jeep Liberty Has the Tow Package Wiring?
  • With your 2006 Jeep Liberty, the factory tow package wiring is not easy to distinguish. If you have a factory 7-way that makes it easy as you know that the tow package wiring is there. The main difference between the tow package and no tow package is the wiring for the tow package gives you the rectangular connector under the vehicle that the 7-way # HM42190 plugs into. You can also use the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118381 which plugs into the...

  • Recommended Trailer Wiring Harness for 2012 Jeep Liberty
  • The wiring harness # 118524 is not a fit for your vehicle but does still require the 12V power wire. The correct fit for your 2012 Jeep Liberty is the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118554. This harness will connect to the factory wiring behind your tail lights on each side and will require the 12V power from your battery. By drawing power directly from the battery it protects your vehicle from circuit overload and damage to your electrical components....

  • Trailer Wiring Harness on a 2005 Jeep Liberty with Factory Installed Trailer Hitch Receiver
  • If your 2005 Jeep Liberty has the factory tow package there will be a rectangular shaped connector under the rear bumper. I've attached a picture to show you what the connector looks like. If you find it you can install a 4-way and 7-way connector using # 20135. If that connector is not there then you'll need to use a T-One wiring harness like # 118524 which installs behind the tail lights of the Jeep. Then there is a hot lead wire that is run to the battery to power the harness....

In order to install a 7-Way, you will want to start by adding a 4-Way connector. I recommend the Tekonsha T-One Vehicle Wiring Harness # 118524.

  • The most efficient way to determine if your vehicle has the tow package is to take your VIN number to a Jeep dealer and have them run it. They will be able to tell whether or not you have the tow package with that information. Or you could check the wiring in your vehicle to see if the correct connectors are present on your vehicle. Check out the installation instructions I attached that will show you how to access the area. If you have the tow package, or if you find the harness...

  • Wiring Harness Recommendation for a 2004 Jeep Liberty Without a Tow Package
  • I verified with my contact at Hopkins that the Hopkins Plug-in Wiring Harness, # 42475, will work on your 2004 Jeep Liberty if it did not come with a tow package. He also stated that the factory connection is typically on the passenger side, but it may be possible that the manufacturer routed the connection to the driver side. I would recommend checking the passenger side for a connector before attempting to connect it to the connector on the driver side. One thing that you will...

  • Plug and Play Trailer Wiring Options for 2005 Jeep Liberty W/O Tow Package
  • We do indeed have two plug and play trailer wiring harness options for your 2005 Jeep Liberty. If your trailer has minimal lighting- just a stop/turn/tail light for the passenger and drivers side, the Curt # C55382 would be an excellent choice. This harness has a simple installation, which would plug inline with the connectors on the back of the taillight assemblies. If your trailer has more extensive lighting, say what is mentioned above plus some clearance and/or marker lights on the...

  • 3 Trailer Wiring Harnesses Converters have Blown and Blew Fuses on a 2007 Jeep Liberty Limited
  • Trailer wiring harnesses that have a power wire that connects to the vehicle battery such as # 118524 use that wire to actually power the trailer lights. It would still plug in line with the vehicle tail light wiring though to get the correct signals. The power wire would not necessarily prevent the problem from happening. If this issue is happening and you are not using the harness to connect to a trailer then I anticipate a problem where the wiring harness plugs into the vehicle....

  • Trailer Wiring Harness Options for a 2002 Jeep Liberty
  • Oddly enough a tow package will not necessarily include a trailer hitch. Evey vehicle manufacturer has a different set of components that make up a towing package. The only definitive way to determine if your 2002 Jeep Liberty has a tow package is to have a dealer run the VIN number of the vehicle to tell you what options it has. f you find that your Liberty did not come with the tow package, then it will not be set up from the factory to accept the # 42475 harness. You will instead...

  • Trailer Wiring Harness Recommendation for 2005 Jeep Liberty Renegade
  • The wiring harness I recommend for your 2005 Jeep Liberty Renegade is the TowReady # 118524 because this particular 4-pole wiring kit offers the highest current output capacity. That means your trailer's lights will be brighter and you'll be less likely to have any overload issues. This wiring harness simply plugs in to your Liberty's tail lights, as shown in the linked video, and you'll have to route and splice only one wire. That wire routing process is outlined in the linked article.

  • How To Connect 4-Pole Flat Vehicle Connector On Jeep Liberty To 5-Pole Flat Boat Trailer Connector
  • On your 2006 Jeep Liberty the Tow Ready T-One Wiring Harness, # 118524, is the correct wiring harness. Using the Tow Ready Adapter 4 Pole to 5 Pole Trailer Wiring Adapter, # 20036, will work on your vehicle to give you the adapter to plug into your trailers 5-pole connector. That would be everything you need, no other wiring or adapters. The 5-pole connector on the Tow Ready adapter will plug into your boat trailers 5-pole and the other end will have a 4-pole connector that will plug...

  • 2011 Jeep Liberty Factory Tow Package Wiring Stopped Working After a Short Circuit
  • On the 2011 Jeep Liberty with factory tow package there are fuses for the wiring in location M2 and location M4. If those are good then you can inspect the actual trailer connector and wiring going to it to see if the short caused significant physical damage causing the problem. If it is neither the fuses nor the wiring/connector then there is likely a deeper issue, possibly related to the vehicle computer. Since it is OEM tow package wiring the best thing to do in that situation is...

  • Trailer Wiring Options for a 2006 Jeep Liberty without Factory Tow Package
  • There are a few different trailer wiring harnesses available for the 2006 Jeep Liberty without the factory tow package. I have included a link to them for you. I recommend either # 118524 or # C55382 because they plug in line with the tail light wiring on the vehicle. These are the harnesses that fit because the vehicle does not have the factory tow package. Models with the factory tow package are pre-wired with a trailer connector already and the wiring for it is under the vehicle.

  • Availability of Ball Mount with 10 inch Rise for Class I Trailer Hitch on 2005 Jeep Liberty
  • The highest rise on a ball mount we currently offer that is compatible with a Class I trailer hitch is the Curt # C45028, which has a rise of 5-3/8 inches. Higher rise ball mounts are only compatible with higher rated hitches. If you need this additional rise to tow your trailer level with your 2005 Jeep Liberty, I recommend changing to a Class III trailer hitch like the Draw-Tite Max Frame # 75128. This will give you a tongue weight capacity of 500 pounds and a towing weight capacity...

  • 6 and 7-Way Trailer Connector Mounting Box Recommendation for Draw Tite Hitch on 2004 Jeep Liberty
  • I spoke with my contact Draw-Tite and he informed that the cross tube is 2-1/2 inch by 2-1/2 inch. Because of this I would recommend you use a 6 and 7-Way Trailer Connector Mounting Box # 18156. I attached installation instructions and an installation video for the # 75128 for you to check out also.

  • How to Pick Trailer Wiring Out for a 2004 Jeep Liberty
  • Like you said there are two different trailer wiring options for your 2004 Jeep Liberty that does not have a 7-way. The Tow Ready kit part # 118524 requires a wire to run up to the positive post of the battery and the Curt # C55382 does not. The benefit to running the wire up to the battery is that it protects the tail light circuits of your vehicle. Instead of drawing the amperage required to power the trailer lights from vehicle taillights the amperage comes straight from the battery...

  • Trailer Wiring Recommendation for a 2004 Jeep Liberty
  • The difference between the Curt Wiring Harness # C55382 and the Tow Ready Custom Fit Vehicle Wiring # 118524 is basically just the brand. Both of these products will install the same and will perform the same functions. I usually recommend the Curt harnesses because they use a newer style of circuitry that has proven to be more reliable. Also, you will need to run the power wire to the battery otherwise the harness would not work. The reason for the power wire is to prevent overdrawing...

  • Recommended Trailer Wiring Harness Options for 2002 Jeep Liberty
  • If you're comfortable with the process of using a circuit tester like # 40376 to locate which circuit serves which taillight function, and then tapping the input wires for the Hopkins # HM48915 taillight converter into those circuits, you can certainly use that option. This being said, the Curt # C55382 converter would be a plug and play option that would be much easier to install. Better still would be the Tow Ready # 118524. The Tow Ready is also a plug and play option, but instead of...

  • Troubleshooting Smoke and Melting Trailer Wiring on a 2002 Jeep Liberty After 4-Way Install
  • Most likely the problem you described is from a short on the trailer wiring. Running a powered converter is a great idea as it protects the taillight circuits of the vehicle it is installed on. But if you are seeing smoke, melted wire, and fuses blowing immediately the problem is a short somewhere on the wiring that is WAY overdrawing the circuits. If the smoke started after plugging the harness into your trailer then the problem is the trailer wiring, if the smoke started after plugging...

  • Troubleshooting Tail Light and Brake Light Issue When Using T-One Vehicle Wiring Harness # 118524
  • To pinpoint where the problem is actually occurring, I recommend using a circuit tester to check for function at the 4-Way plug on your 2007 Jeep Liberty, without your trailer connected. We offer part # ALL640595, if needed. With a helper in the cab of the vehicle and the tail lights on, check to see if you get a power reading on the yellow and green wire ports when the turn signal is flipped or the brake pedal is pressed, as these would be the turn and brake signal wires. For example,...
