Installation

This custom-fit T-One connector plugs into your vehicle's junction box, which is located in your rear cargo area, behind the driver's-side trim panel in the spare tire compartment. You will need to remove any cargo nets and the cargo floor hatch your paneling to access this harness. Once you've plugged in the connector, insert the provided fuse into the vehicle's junction box.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your jack storage compartment.


It is recommended that you use a small amount of grease on all electrical connections - the plug 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 - 2016 Acura MDX

Today on our 2016 Acura MDX we're going to be taking a look at and installing the T-1 Vehicle Wiring Harness with a 4 Pole Flat Trailer Connector. Part number 118628. Here's what it's going to look like once it's installed. This is going to provide you with a 4 flat trailer wiring to allow you to tow most of your smaller trailers. It is compatible if you wanted to add an adapter to change it from a 4 flat to a 6 or 7 way connector. The power module light is going to reduce stress on your vehicle's wiring system.

It's simply a plug and play operation. You don't have to cut any wires or splice, which is a good thing with today's electronics that are in our vehicles. This is what your kit's going to consist of. We're going to have our module, our inline fuse that's going to plug right into our factory fuse box in the back of the vehicle, and our 4 flat connector with a weather-tight cap. It also comes with a couple of fuses that we're going to put into our factory wiring, some 2 sided tape and some zip ties. Now let's show you how to install it. To begin our install we're going to need to gain access to the fuse panel.

Take this cover, we'll slip it back. We'll reach in and pull out this cargo pocket. We're going to need to gain access to our fuse panel that's located behind this cover here. We'll take a flat bladed screw driver and pry it out at the bottom. We'll find the area that we're going to plug in our trailer wiring that's going to go right here in the bottom of our fuse panel.

We're going to take our wire with our plug on it, we're going to fish it through the back side here. We're going to bring it out and we're going to snap it in to our panel. We heard it click, give it a tug make sure it's nice and tight. We still have access to the built in fuse holder for our module light. Now we're going to need to ground our system. We're going to use a factory ground that's located here in the back side.

We're going to tie into the factory ground. That's a 10 millimeter bolt, we'll remove that and we can apply our ground wire. Place our bolt through the ring loop connector and we'll reinstall our factory grounds. Now we'll take a little rubbing alcohol, we're going to clean off the area that we're going to mount our control box. Put some 2 sided tape on the back. Peel it off and we're going to attach our box right there. Press it into place. Now we're going to need to put a couple of fuses in our fuse panel. Our kit's going to come with a 10 amp and a 7.5 amp fuse. The 10 amp is going to go in position 2. We'll place this into position 2. We're going to push it all the way in until it's flush with our panel. Our 7.5 amp fuse is going to go into position number 11. That's going to be our fourth cavity over. We had 1 large one and then 3 small ones. This will be in our fourth one. It's the one that it'll get our 7.5 amp, going to push that down firmly into place. We want to double check to make sure that our fuse is installed properly into our inline fuse, which is a 15 amp. We can reinstall our fuse cover. Snap it back into place. Now we can test our wiring harness. We'll remove our weather-tight cap. We're going to use the Curt Trailer Wire 4 Flat Tester, part number I26 available on our website to test our system. We'll plug it in. We're going to try our tail lights, our left turn signal, and our right turn signal, and our brake. Good, everything works. Normally you would just lay your trailer wiring over the threshold and close the gate on it for a 4 flat design. Our customer is going to add on a 7 way later on, so we need to run this wire outside the vehicle so we can plug into our 7 way connector when they're ready to do that install. We found there's a grommet underneath this perforated area, there's a rubber plug that goes outside the vehicle. We're just going to cut that rubber plug. We'll remove that plug with a flat bladed screwdriver. I'm going to take it and go underneath this rubber mat so we can put it back down and cover everything back up. We're going to place this under the mat and we're going to cut a little notch in our cover here, put our wire through, and we can silicone it back up. We can remove that piece we cut out. Take our plug and we'll pass it back through the vehicle to the outside. We'll slide our wire into the grommet that we put the groove in, we'll snap it back into position and we can zip tie our wiring to our factory wiring, snip off our excess. We're going to take a little black RTV available on our website, and we'll place a little bit of silicone on here to help seal out all the dirt and moisture. We can place our storage bin back into position, this will fit over the back side and it'll just drop down. Everything's hidden underneath. We just close up our hatch. Now we can bunch up our excess wire and we're going to zip tie it to the tube on the back of our hitch. We'll attach our 4 flat for now until we decide to do our trailer braking, or 7 way connector, to the bottom side of our bracket. Trim off our excess and we'll be ready to hit the road. That's going to do it for our look at and install of the T-1 Vehicle Wiring Harness with 4 Pole Flat Trailer Connector, part number 118628 on our 2016 Acura MDX.

The wiring harness for a trailer hookup worked perfectly and the video on how to install the item was spot on. Perfect, couldn't be happier. This was my second purchase from etrailer, first experience was equally good. 415374

Excellent equipment and service. Ordered the custom hitch for our 2016 MDX (same frame and connections as 2014-2015 MDX). Easy to install thanks to the instructional videos, less than 30 minutes. Quality is superb and works great. Will be able to tale our bicycles with us on vacations and use cargo trailers. The connections for wiring was also very simple and exactly as shown in the video. Had a hitch for our new MDX with wiring for less than $300, a dealer option would have cost over $800. Customer service is superb. Had to modify order to include a bracket. Ana held my order and added the bracket and send my order same day. This is our third hitch from etrailer.com (had one for our previous honda odessey and for Acura RL) and are very satisfied. 184167

The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector is the easiest harness I have ever used. In all fairness, the Acura MDX with it's pre-wired connector and separate fusebox simply make the job that much easier. The harness from E-trailer is really good quailty. I honestly completed the job is less than 5 minutes! The instructions were OK, but I also utilized their videos to get a little better insight on the job. The E-trailer website and ordering process was a breeze and the package even arrived a day early. Would have ordered from [site] but they are beginning to get so many knock offs, I decided to go with e-trailer so I would get the "real" thing. 339048

I bought their own branded trailer hitch and it is excellent quality. I had it installed by myself in 10 minutes, really. The lighting controller took another 10 minutes. It all worked perfectly for a price that rivals the big internet sellers. What sets etrailer.com apart from the others is service and support. They have excellent product information so you know exactly what you are getting and how to install it. If you need support, they are there for that too. 634359

I received the etrailer hitch about the same as many others - that is, the box had a hole torn in it, but there was no damage to the product. (I'm not sure how this product could be shipped without tearing the box unless the box was double or triple thickness.) I watched the videos a couple times and then set out to install the hitch. I am 69 years old and was doing this alone on my garage floor with the MDX on the garage floor - not jacked up. It would be MUCH easier if you had two people and had the vehicle in the air on a lift to get to things easier. 2 people would make it a 20-30 minute install, however, it took me 1 hour to install the hitch. Used a small floor jack to raise the hitch and two jack stands to hold it in place while I got the bolts started. I didn't have a torque wrench that goes to 139 lbs, but a neighbor did, so solved that issue. The Tekonsha wiring harness was also an easy - 10 minute or less install. Very happy with the products and would recommend to anyone. Hitch fits great and looks good. Now, I just need to buy that utility trailer so I can use the hitch. 610382

Instructional video online from etrailer was very good. It had more information than the instructions that came with the Tekonsha wiring harness, it was missing hooking up the ground wire. 2018 Acura MDX SH-AWD. I do not tow a trailer very often with this vehicle so I am leaving the pig tail inside and will run it out the rear door when needed. 592638

Ordered the trailer wiring for my 2014 MDX. It arrived within just a few days after I ordered it. Watched the online video on how to install, read the instructions on how to install and went to work. It took less than 10 minutes to install. Also bought my hitch from etrailer with the same results. Easy to install. In total I saved a few hundred dollars doing it myself. Especially helpful were the online videos. I highly recommend the company and their products. 274048

delivery was quick. Trailer hitch was packaged well, good thing since shippers punched two holes in the box. Install took just over an hour for the trailer hitch and about another 15 min for the wiring harness. Wiring harness was easy to install but the diagrams were difficult to read and I wasn't sure if it needed two fuses or just the one 7.5 that came with it...less than 300 dollars and two hours time for what the dealer wanted 1200 for. 260233

Wiring harness shipped was very useful, easy to install; although the advantage is on the vehicle OEM because our MDX was pre-wired and required simple plug-in. One minor point, the kit came with a 7.5 amp and a 10 amp fuse, but the fuse box on the car map for the trailer reverse and stoplights required a 10 and 20. I was able to use the 10, but had to get my own 20 amp. 224630

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2015 Acura MDX
  • For many vehicles, including your 2015 Acura MDX, there isn't a plug and play type of 7-Way trailer connector so one has to be hardwired in. This is because on those vehicles the vehicle itself is not set up for a 7-Way trailer connector. To add one you would first need to install a 4-Way which will provide the light functions for the trailer. For your MDX you can use # 118628 to add the 4-Way. Then to add the 7-Way you will need # ETBC7. The 4-Way will plug into the ETBC7 leaving...

  • What is Converter Box for On Trailer Wiring Harnesses for 2018 Acura MDX
  • The black converter boxes you see on the trailer wiring harnesses for your 2018 Acura MDX are needed because the vehicle has a separate wiring system. This means that the brake and turn signals are sent along separate wires. Since standard trailer wiring uses the stop and turn signals on the same wire, a converter module is needed to combine these signals. The powered converter also helps to safeguard the factory wiring on the Acura and ensure that there is enough power to activate the...

I spoke with two of the lead techs at Tekonsha and neither of them have ever heard of this issue before therefore, I think it is safe to say that the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118628 has everything that you need and you don't have to go to the dealer for any relays. There are however fuses included with the kit you...

  • 4-Way and 7-Way Trailer Wiring Recommendation for Towing with a 2018 Acura MDX
  • To start off you need a 4-Way connector on your 2018 Acura MDX. I recommend the Tekonsha T-One # 118628 because we have found the Tekonsha wiring to be the most reliable and it has the highest amp ratings so it can deliver more power to the trailer lights. Then to add a 7-Way connector you need to install the Universal Wiring Kit # ETBC7. This includes the adapter as well as all of the wiring and connectors needed to add a brake controller to your Acura MDX. If you don't already have...

  • Recommended Trailer Hitch and Bumper Clearance for 2015 Acura MDX
  • The Curt hitch, # C13146, has 2-3/4 inches from the center of the hitch pinhole to the outermost edge of the bumper and will have the most bumper clearance. The Hidden Hitch hitch, 87649, has 4-1/2 inches of clearance from the hitch pin hole to the end of bumper. Both hitches have 14 inches of clearance from the receiver to the ground. The Hidden Hitch is no longer manufactured, but has been replaced by Draw-Tite (sister company) # 75225. So if increasing the space between the bike...

  • Does Installation of Curt Trailer Hitch C13146 Void Warranty on 2016 Acura MDX
  • When you install an aftermarket part on your vehicle, such as a trailer hitch, you are protected by the Magnuson–Moss Warranty Act. This act states, in part, that unless the installation and the part caused a problem then the warranty cannot be voided just because you added a part to the car. All of the 2-inch Class III hitches offered for your 2016 Acura MDX are bolt-on products that install using existing holes in the car's frame. No drilling, trimming or other permanent modifications...

  • Recommended Trailer Hitch and Towing Accessories for 2014 Acura MDX
  • For your 2014 Acura MDX, I'd recommend the Curt Class III Trailer Hitch, part # C13146. When installed, the hitch will be almost completely concealed behind the bumper, with only the receiver tube being visible. There isn't a Class I hitch available for your vehicle, but the 2 inch receiver is much more popular, and will have a much better selection of hitch mounted accessories like bike racks and cargo carriers available. If you'll be towing with your hitch, you might be interested...

  • Parts Needed to Install a P3 Brake Controller in a 2015 Acura MDX
  • The Prodigy P3 # 90195 is an excellent controller that can be installed in your 2015 Acura MDX. All you need is to install the proper wiring. You will need to start with a 4-way (if you do not have one). For that you would want the # 118628. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install...

  • How Far Past the Rear Bumper Does Curt Trailer Hitch Stick Out on a 2015 Acura MDX
  • When we installed Curt trailer hitch # C13146 on a 2014 Acura MDX the face of the hitch receiver has almost flush with the back of the bumper, see photo. It stuck out maybe 1/2 an inch. This should keep your shins bruise-free. I have bumped into hitches before and it does hurt. This one doesn't really stick out far enough to be a problem. The hitch does come with the mounting hardware. If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It includes 2 ball...

  • Does the Trailer Wiring Bracket of the 75225 on a 2016 Acura MDX Fit Below Rear Bumper
  • Actually the trailer wiring bracket of the Draw Tite hitch part # 75225 that you referenced comes out right under the rear bumper of a 2016 Acura MDX. If you check out the picture I attached I pointed out the bracket with a red arrow and you can see it right under the bumper. For a bracket to attach to the bracket on the hitch you would want the part # 18144 for use with the # 118628 which is a fit for your 2016 Acura MDX.

  • Recommended Ball Mount Trailer Ball and Trailer Wiring Harness for 2016 Acura MDX
  • A standard 2 inch trailer ball would have a 1 inch diameter shank, like the # 63845 from Tow Ready. You'll want to make sure that the ball mount you choose has the same diameter hole as the shank of the trailer ball. The rise or drop of the ball mount you need will depend on the coupler height of the trailer you're wanting to tow. I've linked you to an FAQ article that explains how to determine the rise/drop of ball mount you need. A standard length ball mount would work just fine. When...

  • Trailer wiring harness # 118628 fits both the 2015 and 2016 Acura MDX. I have included a link showing an example installation for you. For a trailer hitch the most popular option and what I recommend is # C13146. I have linked a video showing an example installation of the hitch as well. I also recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball,...

  • Will Installing Draw-Tite 75225 Interfere With Spare Tire of 2015 Acura MDX
  • The Draw-Tite Class III, part # 75225 would not interfere with installing/removing the temporary spare tire on a 2015 Acura MDX. The available hitches are compatible with the 18 inch full-size spare tire, but not the 19 or 20 inch spare tires. If you'll be using the hitch for towing, you might also need the following to complete your towing system: Trailer wiring harness with 4 pole trailer connector, part # 118628 Ball mount, part # 2923 2 inch trailer ball, part # 63845 1-7/8...

  • Recommended Trailer Hitch for 2018 Acura MDX
  • Each of the three trailer hitches that fit your 2018 Acura MDX - the Draw-Tite # 75225, Curt # C13146 and etrailer # e98840 - have the same capacities, which are 900 lb tongue weight and 6,000 lb towing. Please keep in mind that you do need to follow the towing capacity found in your Acura's owner's manual; I took a look at an online copy and found that for an '18 MDX the capacity will range from 2,500 lbs to 3,500 lbs depending on the number of occupants and cargo.

  • Everything looks perfect! Starting with the wiring harness, the Tekonsha T-One Vehicle Wiring Harness # 118628 that you referenced is confirmed to fit your 2014 Acura MDX and is exactly the harness that I would recommend. This custom-fit harness will install by connecting directly to the built-in port behind the driver side trim panel. This will give you a 4-Way at the rear of your MDX to connect with and power a trailer's signal lights. I have attached an installation video on your...

  • Does Battery of 2018 Acura MDX Have to Be Disconnected to Install Trailer Wiring
  • Normally it's always a good idea to disconnect the vehicle battery any time you are working on anything electrical, but for the Tekonsha wiring kit part # 118628 there is no mention of disconnecting the battery prior to installing the kit so it would not be needed.

  • Trailer Hitch Recommendation for 2018 Acura MDX
  • The hitch I recommend for your 2018 Acura MDX is the Draw Tite hitch part # 75225 because it is a 2 inch hitch size with plenty of capacity, has a hidden crosstube so it will be less visible, and because it has a 4-way mounting bracket built into the hitch. I attached a picture of this hitch installed as well as an install video for you to check out as well. For trailer wiring I recommend the T-One kit part # 118628 because it does not require any splicing to install and it has our...

  • The T-One Vehicle Wiring Harness # 118628 you referenced for your 2019 Acura MDX only carries the running lights and turn/brake light functions but we do have a way for you to add the reverse light function as well. Since all 4-Way wiring harnesses like the T-One carry these same functions you will need to use an adapter like the Tow Ready # 20036 which changes your 4-Way to a 5-Way that adds the reverse light function to the extra pin. Simply us the quick-splice to connect the blue...

  • Recommended Trailer Hitch for 2018 Acura MDX
  • The best trailer hitch for your 2018 Acura MDX is the etrailer.com Class III # e98840 because of its hidden design, robust towing capacity of 6,000 pounds, and the fact that it is made right here in the USA. I also really like the unique matte black finish on this particular hitch that gives it more of a rugged appearance and also helps to prevent any scratches. This Class III hitch features a hidden-crosstube design where only the 2 inch receiver is visible behind the vehicle (see...
