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.
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.

Today on our 2014 Ford Flex, we'll be installing the tow-ready T1 vehicle wiring harness with a four-pole flat trailer connector, part number 118472. In conjunction with our tow-ready wiring, we're going to be installing a short bracket, part number 18140, as well as the four flat connector bracket, part number 18144. To begin our installation we'll need to raise the rear hatch of the vehicle. In order to remove the tail light assembly, we'll need to take out this bolt here and this bolt here. Once we have the two bolts removed we'll need to gently pull towards the rear of the vehicle on the tail light assembly as there's a couple more tabs that we'll need to release that are behind the light assembly. Next we're going to disconnect the wiring from the back side of the light assembly. We'll push in right here on this little locking tab and gently pull outward. We'll go ahead and repeat the same process over here on the passenger side.
Now we're going to go ahead and take an old section of air line tubing here and use it as a pull wire. We'll go ahead and feed it down from the top side down underneath the rear bumper fascia. Going to go ahead and tape our wiring off here to our pull wire. Now we'll go ahead and pull up our wire over here on the driver's side, and on the driver's side you'll be pulling up the yellow, the brown and the white wire up into the tail light assembly area, so when making our connection here we'll be tying in this side of the T connector with the factory wiring plug that go together like this. You push it together, you want to make sure that you hear it click into position and that the locking tab secures it. We're going to then need to take the self-tapping screw supplied with the kit and attach our white wire here with the ring terminal on it to the body of the vehicle. Now we'll go ahead and take the other half of our T connection, plug it into the back of the tail light assembly.
Again, you want to make sure that you hear it click so that you know its locked into position. Now we're ready to go ahead and reinstall our tail light assembly. Line up the two tabs in the body here. Once you have the two tabs pushed back into place, we'll reinstall the two bolts that we removed earlier. We'll go ahead and take our wires, we'll route the four flat to the center of the vehicle and the green wire with the two connections on it, we need to route that all the way over to the passenger side. When routing your wire, you want to make sure you stay away from any areas that may become hot or move or have sharp edges, as they could all easily damage the wire. We'll be using a few zip ties along the way to help secure the wire.
As we did over on the driver's side, we'll again over here on the passenger side use our old section of air line tubing to help fish the wire up into place. Now that we've got our wire pulled up into position, we'll go ahead and connect half of the T connection to our factory wiring. Slide it in place and make sure you hear it click so that it's secure and locked into position. We need to go ahead and plug the other half of the T connection into the back of our light assembly. We'll then go ahead and reinstall the tail light assembly. We're going to go ahead and attach our four flat bracket to our short bracket here first, using the supplied hardware. Next we're going to go ahead and feed our four flat here through the large opening in the short bracket and then we'll put it into the four flat bracket.
To protect the wires here a little bit, we're going to go ahead and add a small section of half-inch wire loom over the wires right here and use a couple of little zip ties to help keep it in place. Go ahead and trim off the zip ties to clean up our look. We'll then go ahead and take our bracket and slide it over our hitch. We're going to take the hose clamp that comes with the kit, slide it around the hitch and through the bracket and come back down to itself here, feed it back through, then go ahead and tighten down our clamp. Go ahead and trim off the excess of the clamp. Now we'll go ahead and trim off any excess zip tie to help clean up our install look. Now we'll go ahead and test out our new flour flat. We'll put the ground on our open prong in the four flat, we'll then turn a running light circuit on. As you can see here, that's working fine. Left turn, right turn and brakes. So we have brakes. As you can see here, all of our functions are working just fine. That'll do it for the installation of our tow-ready T1 vehicle wiring harness, part number 118472, on our 2014 Ford Flex. .

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 - no cutting, splicing or tapping required.I professionally installed this trailer wire on my Ford Flex 2011. It corrupted my wiring system in 2 weeks. It made my running lights on my Flex to not work at all. Secondly, this product is after market which voids your warranty. The only wiring that the Flex can handle is from the front fuse box. I learned the hard way and had to have this wiring removed from my Flex which cost me an additional $68 dollars. I strongly suggest not using this product and have Ford install your trailor light wiring since it will not void your warranty. 20160
Photos of our T-one wiring harness install this afternoon on our 2012 Ford Flex. Should be comprehensive, but I have a few other photos. I ziptied to the factory harness where I could, and had to clip the last one of your zipties to get enough slack. Ground wire unzipped a little. Drilled & Dremel'd off the finish, then used "Noalox" between the ring terminal & body, then sealed with caulk. I will add some split-loom later where the trailer plug wiring goes into the backside of the tow bumper. I added electrical tape to the green wire (not shown in photos), and any other place I thought might rub. 4-pin connector just wedged into the factory slot. 97913
Overall good product, work as intended. Only thing I would change is the ground eyelet. Im not drilling into tge body of my car for a rust area later in it's life. I added a larger eyelet and put the ground on the hitch mount bolt. 526790
Incredibly Easy to install. Do read the instructions, it does make it little easier to understand which color of the harness goes on which side of the tail light. Take the tail lights out, unplug your brake light plug, clip in the provided harness, plug your tail light plug back in, put the tail light back on, secure it with bolts and hide the wires. That was easy. Great product and sure beats cutting, pinching or soldering of the aftermarket harnesses onto the OEM wires. 443064
We installed the hitch and lights in about 2 hours. The light set was perfect and the hitch was such a breeze. I thank you for fast shipment. 703247
This trailer hitch performed like it should. The staff was very helpful. 699680
Worked perfectly. Installed easily. 699102
Fantastic 681088
Easy. Plug and play. 30 min. Install. Could use a few more zip ties (not a big deal) 671987
After 3 1/2 hours we got the hitch and wiring on. First off, holes wouldn't line up because hitch was hitting spare tire well, so had to grind off corner of hitch to clear. Then slots were spaced too far apart (from one side of car to other) so we had to file 1/8 inch out of slots so that we could get screws to line up with holes in car. When it came time to install wiring kit after an hour or so I finally cut the single wire going to the right side and dropped the wire down from the top and then respliced the wire. I just couldn't pull the end of the wire with all the connectors on it up through the small access area. If you would install a small connector on the single wire so that you could disconnect the end of the "right" wires drop the end of the wire down and then reconnect the wires like I did it would save splicing the wire back together and making it much easier to install that "right" wire. 667298
Wonderful product. Excellent customer service. From the product descriptions in the beginning, the installation instructions and the personalized follow up, working with etrailer.com is what you expect from a top-notch company. I will note, however, that the installation is not a one-man job. An extra set of hands would of come in helpful. I used a set of jack stands and my vehicle jack to improvise and to help lift the hitch into position until I could get a bolt to catch. After that it was all a breeze as the hitch utilized existing holes on the frame. No drilling! Even the wiring was made simple and fool proof. I would definitely use this company and product again. 661449
Video was a great help but there was a little more trouble getting the wiring up past the fender. Visited needs to show how it was routed towards the from hole or back one. 659999
Perfect fit for my 2014 Ford Flex. Easy to install. Works great. 653459
Great service! Order arrived complete in two days. Everything fit and worked as promised. Everyone, get all you towing needs from etrailer. Definitely recommend to others..... 653273

I ordered the wire set along with the tow package. Everything fit perfect! 633255
This harness is a very nice option and a must for trailer wiring. Product was very well packaged. Instructions are very clear and easy to follow and installation was very smooth. 613103
I ordered my wiring harness after seeing a utube video on the installation. I worried that it might not be quite so easy as it looked, but actually it went very smoothly, with no problems. It was the exact unit I needed, and fit great. No complaints at all. A+! 604241
Fantastic product and easy to install! Customer service was awesome and even refunded the difference of shipping charges due to my mistake and called back to let me know when to expect my order. Thank you again! Happy Holidays! 592482
I was supprised how nice it was. 586075

We were extremely satisfied with the wiring harness on our Ford Flex. Simple instructions and easy to install. 543996
Super easy to install. Just find the factory hole behind tail ight and use fish tape to get wiring harness up through body. Simple plug in then tie wrap all wires up under hitch. Don't need the more expensive versions of wiring harness. 530153
Good product easy to install. Do not pay someone you can do it you self. 516681
A lot easier to install than CURT uses a fused main power wire from battery a real pain on Ford Flex & short life only last about a year. etrailer works PERFECT without the hassle 499651
I ordered a hitch receiver and electrical installation kit for a 2009 Ford Flex. Installation was super easy and so far everything is working great. We did have an issue with payment processing but the company fixed it right away with no issues and were very friendly doing so. 497100
Plugged right in. Plenty of extra wire to make it fit. 492205
This was a no-brainer purchase and install for me. I'm not a big fan of splicing in any connectors do a factory wiring harness. So when I saw this I jumped on it and didn't look back thank you for the product 489124
The installation video and the product were straight forward. 487826
It worked. Not much more to say. 483470
Installed along with my trailer hitch. This is a pull and play harness which requires no cutting and installs in series with your factory connection and your rear light module. 483206
the plug and play to wiring is fantastic. I have had two vehicles now there I have been able to install in series wiring for towing behind my RV and a tow bar without having to cut in to any wiring
Kenny - 03/11/2019GOOD PRODUCT VERY HAPPY 482503
Easy to install, worked like it was intended to. 477006
Very easy install! The only tough part was where to support the wires under the bumper. There is not a lot of options on my Flex. I didn't want to tie them to the hitch, so it took a little longer to secure them to my satisfaction, As far as the comments about the flasher activating rather quickly when the harness is plugged in.....I have not experienced that at all. It works like it was expected to. 473981
Works great. Decided to use longer and heavier ties for connector bracket. 2015 Ford Flex Limited 471597
Glad to do business with you. Product works great. 463982
Great. Love it.

looks good I'll get it installed in a couple of days. 436048
Wow, a follow up after a year! I honestly only used it once so far. But it was an 800 mile tow. All went well, good value, good quality piece.
fred 6 - 09/24/2018Super simple install, made easier with a how-to video on youtube by etrailer.com 434877
Good fitment. No issues with installati on. 427472
Works fine! 427165
I chose to install the wiring harness first. It was designed to fit the existing vehicle harness with a couple of perfectly fitting sockets Routing was easy and used my personal choice for securing. The hitch was obviously designed for strength and durability with good powder coat paint and faultless welds. Installation was simple but for me I needed two more hands to lift and hold in place until the four bolts were secure. I do not foresee any problems in the years ahead. The pricing was good and free shipping was appreciated. All contacts with etrailer were professional and knowledgeable. 419426
I am pleased with the hitch and especially the wiring harness. Would recommend your products to anybody. Nice to do business with a quality company with quality products!

The hitch kit for my 2015 Ford Flex was a perfect fit and the wiring kit was an exact match. This was a simple installation. A friend and I did this install in less than an hour, start to finish. I am now able to tow my trailer & carry the quads to the dunes. Thanks for everything. I will recommend etrailer.com to all my friends. 376182
