Installation
This custom-fit T-One connector plugs into your vehicle'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 the threshold panel and some of the trunk liner to access the harness. Once you've plugged in the T-connector, run the hot lead with the attached fuse holder up to your car battery. Connect the fuse holder to the positive terminal on the battery and insert the provided fuse.
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.
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.

Great website, great prices, extremely fast shipping. This is the fifth hitch that I have ordered over the last ten years and always pleased
Great folks to work with.

Hitch for my 2020 Explorer shipped immediately, was well made, and included the wiring. The cost for this hitch and the installation was less than the factory hitch, and it is does not require having to pull off a section of the rear bumper fascia every time you want to install the hitch.

Excellent trailer hitch and wiring harness. I am a novice at car mechanics and watched the etrailer Youtube videos and installed both pieces in a little over an hour. Products work perfectly and easy to install. Thanks!

For me the worst thing was running the power wire to the battery. Harness was plug and play and was able to conc by eal power module and wires behind pannels in the back. Was able to run through a body plug the 4 pin connector to the hitch and conceal. Glad I don’t have to do that again.

This company is awesome! They give out out tons of information on how to pick the right parts and install them and install them. Plus the prices are very fair and and delivery service was fas it was fast. My trailer hitch fit perfect and the wiring harness was easy to install thanks to the videos. I highly recommend etrailer and will definitely be using them again for all my automotive needs.

I received my trailer wiring harness very promptly. The harness was well designed and manufactured. I would recommend this product to anyone looking to add trailer lights to their vehicle.
by: Kristofer07/25/2019
Worked for a while, then fried out during my move with the uhaul. Wasn’t the uhaul, as the uhaul lights worked correctly when hooked up to another vehicle. Disappointed.

This wiring harness is confirmed as a fit for your Taurus. It does have a maximum amp of 2.1 amps per stop and turn lights circuit and 5.6 amps for the tail light circuit. It may just be the in-line fuse, I recommend checking that to see if a new fuse would correct the issue. Other than that most trailer wiring issues are related to a bad ground somewhere in the system. I have included a help article regarding this for your reference.

Great Hitch. Ordered from etrailer for $189 and local shop wanted over $400 for the exact same item. Bolted right on and it only took about and hour to be "tow ready". Great prices, Great shipping!
Thanks!

Product is good. Teconsha was a customer of mine when I was working. Etrailer service, web site, installation instructions, and video help are all excellent. Oops, for got shipment tracking, also excellent.

- Installing a Trailer Wiring Harness on a 2013 Ford Taurus SHOFor the easiest installation, the trailer wiring harness that I recommend for your 2013 Ford Taurus SHO is the Tow Ready T-One Harness, # 118599. This harness does not require any cutting or splicing into your vehicles electrical system and it uses power from your vehicle's battery to power the trailer lights. This eliminates the potential for blowing tail light fuses on your vehicle. If you are somewhat familiar with hand tools and have a basic understanding on how to dismantle interior...
view full answer... - Does Power Wire of Tekonsha Trailer Wiring Harness # 118599 Have to be RanThe Tekonsha trailer wiring harness part # 118599 will not work without the power wire connected. This converter box is designed to protect the taillight circuits of your tow vehicle by only using them for signal but then drawing power from the vehicle battery instead to power the lights. This means a trailer wiring short won't hurt the vehicle wiring.
view full answer... - Can Trailer Wiring Harness For 2012 Ford Taurus be Run to Spare Battery in TrunkThe Tekonsha T-One Vehicle Wiring Harness # 118599, which is what I recommend for your 2012 Ford Taurus, will connect to existing ports located inside the trunk and a hot lead with attached fuse holder will then need to be run up to your vehicle battery. Running the power wire to your primary vehicle battery under the hood is going to be your best option, as the battery will be charged by the alternator and will provide a reliable source for the harness. This is the safest way to install...

view full answer... - Trailer Wiring Harness for 2022 Ford Explorer without Tow PackageIf your 2022 Ford Explorer did not come from the factory with tow package, you will need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118599 from Tekonsha. This custom-fit T-One connector plugs into your vehicle's wiring harness behind the tail lights on both the driver's side and passenger's side. Then simply run a hot lead with the attached fuse holder up to your car battery. Please note the linked product review and installation video below.
view full answer... - Where to Run Power Line When Installing Tekonsha Trailer Wiring for 2017 Ford TaurusWhen we installed the Tekonsha trailer wiring harness part # 118599 we ran the power wire underneath the vehicle avoiding any hot exhaust or moving components. If you check out the attached install video link you can see the entire process outlined and exactly where we ran the wire.
view full answer... - Best Trailer Hitch and Wiring for 2014 Ford Focus To Carry A Cargo Carrier With LightsThe best hitch to carry GearDeck 17 Enclosed Cargo Carrier # H00604 on the 2014 Ford Focus is the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75670 because it provides about a 1/4" more ground clearance then the other hitches. The 1/4" more of ground clearance is important when carrying a cargo carrier like the GearDeck 17 or a bike rack because it is less likely to scrape the ground while backing down a hill or other low ground clearance situations.

- 4-Way Flat Vehicle Wiring Harness For a 2022 Ford Explorer Without Factory Trailer WiringThe Tekonsha T-One Vehicle Wiring Harness # 118599 will give you a 4-way flat connector for your utility trailer to connect to your 2022 Ford Explorer. This harness uses factory style connectors so you will not have to splice into the tail light wiring on your Explorer. The Mounting Bracket # 18144 will allow you to secure the 4-way connector on the back of your Explorer to prevent it from becoming damaged if you choose to route the connector outside the vehicle rather than running it...
view full answer... - 2 inch Trailer Hitch Recommendation for 2013 Ford Taurus AWDI spoke with my contact at Draw Tite and he confirmed that the # 75670 is a confirmed fit for your 2013 Ford Taurus with AWD. This is also a Class III hitch with a 2 inch opening like what you are looking for too. For trailer wiring you then would want the # 118599 which is a confirmed fit as well. I attached an install video for this for you to check out as well.

Since your vehicle had the harness stripped out I recommend The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118599. The # 118599 plugs into your vehicle'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 also have...
view full answer... - Recommended Trailer Wiring for 2013 Ford Taurus Police InterceptorI recommend the Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C59496 for your 2013 Ford Taurus Police Interceptor trailer wiring. This will give you a 4-way flat connection that will allow you to work with the unique wiring of a police interceptor and draws power directly from the vehicle battery to protect your electronics. There is not a harness that will plug into factory wiring for your vehicle because it isn't a standard model. This kit will allow you to use quick...
view full answer... - Recommended Trailer Wiring Harness for 2022 Ford ExplorerTekonsha makes an excellent product, but the # 118599 harness you'd looked at won't fit Explorer Police Interceptor models. It also has a slightly lower amperage rating than the Curt # C56093, so I'd recommend going with the Curt harness. I've linked to an install video for the # C56093 harness.
view full answer... - What Does all Pins of 4-Way Harness having Power When Vehicle is off IndicateWhat you described is a shorted out trailer wiring converter box. When all of the pins are hot all of the time that indicates that the box had an internal short and it needs to be replaced. The Curt harnesses are known to short out a bit easier than the Tekonsha kits like part # 118599 which is a fit for your 2014 Ford Taurus so this would be what I would recommend for your replacement. Be sure to go over your trailer's wiring to determine if there are any obvious shorts on it's wiring...
view full answer... - 4-Flat Wiring Harness for 2020 Ford Explorer Police Interceptor without Tow Package I would be happy to help you find a 4-flat for your 2020 Ford Explorer Police Interceptor that does not require the tow package to connect. I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118599. The T-One connector plugs directly into your Ford Explorer's existing wiring without cutting or splicing of wires. The powered ModuLite reduces the strain on your wiring system.
view full answer... - How to Use Hitch Mounted Light Up Accessory with 2020 Ford Explorer and Have Backup SensorsThe Tekonsha trailer wiring harness part # 118599 would be your best solution to power the # BBS-1104L without causing your vehicle to think a trailer is connected and disabling sensors. This kit installs by plugging inline with the taillight connectors at the rear of your vehicle which bypasses the factory wiring altogether.

- Recommended Towing Mirrors For A 2022 Ford Explorer Pulling A Pop Up CamperFor your 2022 Ford Explorer, I recommend the K-Source Universal Towing Mirrors # KS3891-2. I have had good luck with K-Source mirrors and tend to be more secure on the mirror than other brands. The convex design make reflections appear smaller than with flat mirrors, which allows you to see more as well. The ratchet strap and quick release button also makes attaching and removing these quick and easy.

- Comparing Curt and Tekonsha Wiring Harnesses for 2020 Ford ExplorerThe Curt # C56093 and the Tekonsha T-One # 118599 do have some slight differences, but they both install the same way, come with the same basic components you will need to install a wiring harness and will provide you with a 4 way trailer connector. Typically we've found that Tekonsha harnesses have a bit more reliable powered converter on them, but the Curt harness in this case can handle a bit more amperage, so it would be my recommendation for your 2020 Ford Explorer. If you don't have...
view full answer... - How Much Does the Curt CU78FR Hitch Weigh?The Curt Trailer Hitch item # CU78FR weighs 47 lbs. If you are looking for a wiring harness for your 2020 Ford Explorer I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118599.
view full answer... - Can 7-Way Adapter for Brake Controller Install ETBC7L Run Off Same Wire as Trailer WiringYou need to run the power wire of the # ETBC7L kit and of the trailer wiring kit part # 118599 separately as they at any given moment you could over draw the wire if both circuits were pulling their max amperage.

If you also need trailer wiring we have the Tekonsha kit part # 118599 as well which installs easily and has a very reliable converter box as well.
view full answer... - Trailer Lighting Problem Causing Directional Signals on 2011 Ford Taurus to Rapidly FlashNeeding a heavy duty flasher might be a possibility, but before going that route, do a bit of troubleshooting. Check your ground connections. A poor ground connection can cause any number of problems with trailer lighting. On the converter box, there is a white ground wire with a ring terminal on the end of it. Make sure that this wire is securely attached to clean metal. Also, check the ground connection on the trailer itself. Trace the white wire rearward from the trailer connection....
view full answer... - 4 Pole Trailer Connector for 2020 Ford ExplorerFor your 2020 Ford Explorer, you'll want to use # C55384 which would plug into the US Car connector under the rear of the vehicle. If the vehicle isn't equipped with factory tow package that includes the US Car connector, you'd need to use the Tekonsha T-One Vehicle Wiring Harness, part # 118599. You can see installation instructions by clicking the provided link.
view full answer... - Trailer Hitch Receiver for 2020 Ford Explorer That Allows Use of Hands Free LiftgateThe trailer hitch receiver that will work with your 2020 Ford Explorer, and will let you keep on using your hands free liftgate sensor is the etrailer Trailer Hitch # e29YR. What you may need to do is simply kick your foot to one side of the receiver portion of the hitch as opposed to directly in the center, but the feature will absolutely still work. Along with the hitch, if you plan on towing with your 2020 Ford Explorer, you'll need a wiring harness, the T-One Vehicle Wiring Harness...
view full answer... - Trailer Wiring and Hitch for 2020 Ford Explorer without Tow PackageSince your 2020 Ford Explorer does not have the factory towing package the trailer wiring harness you'll need is the Tekonsha part # 118599 which plugs inline with the taillights of the vehicle to give you a 4-way. This would work great with the mostly hidden Class III etrailer hitch part # e29YR that you are considering. I attached install videos for both the hitch and the wiring for you to check out as well.
