Today on this 2010 Acura MDX we are going to install part number 118424. The first thing we need to do is open up the back tail gate to get to the interior components of the vehicle, because we have to remove a few panels. First off we are going to open up this hatch right here and remove it. Then we will take out the cover for our jack storage compartment. Then we will remove our threshold right here . The reason we are moving all these pieces is because we need access to run our wires from the court, out to where we can use it. :27
This panel pretty much pops up on its own. Now that we have this cover up what is going to happen is we are going to run this T-One connector underneath the plastic inside this panel right here. Lets go ahead and remove this panel, there is our electrical panel right here. This is the T-One connector, this is the port on it. We are going to plug in on the port on the panel right here. We will take our port, run it underneath the panel and up. Just plug it in. Next we will take the ground wire and attach it to this ground stud right here. Put it through our white wire and reattach the bolt to the body along with the other ground wires. 1:10
Now we will go ahead and mount our convertor box, it has a piece of adhesive back here that we are going to use to attach it to this plastic piece right here that will be a good, safe spot for it. At this point here we are going to route this back through our jack storage compartment. We can have it reside in the storage compartment when you are not using it. You can then, pull it out, and shut the door on it. The door seal is thick enough where when you shut the door on it, it will not hurt the wires, all you have to do is make sure you stay away from the center latch and you will be fine. However, in this case we are going to run our wires outside and mount it to the hitch itself. So I have to do a couple more things. We are going to find a location to run the wires out of the body. Right in here there is a grommet, we can pop that out and we can have access through to the outside. As you can see that 4-pull will not fit through there so we are going to take our 4-pull wire and cut it in half and run it through and make new connections on the inside. We are going to cut our wire short right here, just enough so you can still work with it. When you do this you want to make sure there is no power going to this so you do not cross a ground wire with the other circuits just in case something is on. We will go ahead and unplug it from the port. Then lets go ahead and split our wires back. Next we will go ahead and work on our grommet, I am going to take a knife and put a slit through it. You have to make quiet a few passes because it is a pretty thick grommet. From underneath the vehicle we are going to push our wire back through. Then we will slide our grommet back on to our wire and push it back into place and leave it alone for now. 2:56
Now we will reconnect our wires, color for color. Slide on the butt connectors and crimp them into place. Now that we have our connections done lets grab some electrical tape and secure them. Then we will go ahead and reassemble the rest of the vehicle. We will plug back into our port. Now we will get back underneath the vehicle and figure out how to route our wires. I think we will just go along the original harness, above the hanger for the muffler and go over the hitch and then we will come back over the top of the hitch here and then we will mount our bracket on top of the tube here. Keep it a flat alignment with the hitch, mark the holes for it, then drill it out. Alright, we will go ahead and pop our 4-pole into the bracket, it is a friction fit so you have to push it on through, get a good grip on it and kind of pull it out. Then install the hardware that came with the bracket. However, on the other side we are going to add some additional flat washers we found laying around. With everything secured and our wire zip tied in place, that will finish our install of part number 118424 from Tow Ready.

Just installed this over the weekend on my 2007 Acura MDX. This is very easy to install. I simply just route the cable out the back hitch door when needed. If you tow/use your hitch relatively often you should probably have a permanent mount for the cable by the hitch receiver. 6419

E for Easy! WOW! I never expected it to be as simple to install as it was. It took all of 20 minutes! The only improvement I suggest is to change the wiring so it can be passed through the rubber grommet down through the trunk.4347

I bought this wiring harness to in the event I need to tow a trailer with my 2010 MDX. Although I haven't had a chance to tow anything it came in on time in perfect condition.

The product was delivered quickly and in good condition and the company sent emails indicating when it was sent and when it should have arrived. It installed easily and the instructions (both those that came with the product and the video on the website) were clear.29082

The harness was easy to install with the youtube video. Just follow the direction shown on the video. I visited U-haul store to make sure it works properly and it does. The process was predictable and I couldn't have done it without the youtube video. The Acura dealer wanted to charge me $400, but i did it myself with $50.28343

If this product takes more than 10 minutes to install you are doing something wrong. This couldn't be any easier. Watch the etrailer video on how to install it, get your 10mm socket wrench for the grounding nut and install it. It took me all of 5 minutes from the time I opened the hatchback to the time I closed it. I wish everything in life was this easy.27334

Very simple to install, took me about 10 minutes with only a socket wrench to connect the ground wire. No technical skills required for this job, definitely something anyone can do. Why pay the dealer $200-300 for this job you can do yourself for about $40.25374

I am very pleased with quality of the Curt hitch as well as the excellent fit. It was a bit tight, but this is a good thing. An extra pair of hands helped with installation. E trailer sent it out quickly and it was received within several days. Much sooner than I expected. Wiring was quick and easy to install. 21974

Product arrived on time but not in a perfect condition. UPS delivered it with paint chips in 3 places. Installation was as advertised. It took me approx 45 minutes to install without lifting the vehicle and doing all this alone. Installation of wiring harness took less than 5 minutes. I used the product almost immediately and it worked great. Overall happy with the product and the ease of the installation. 20199

This is a replacement item that I purchased a few years ago that for some unknown reason went on the fritz. Current getting to the controller but not going thru to the wiring for the trailer. Impossible to take apart to see if fixable so bought a new one. This one works, at least so far. Use the trailer twice a year but think working lights are a good idea. Installation is much easier the second time, not very difficult the first time either. Great service in gettng me the part on etrailer.com.17310

This item is easy and quick to install. This is the second one I had to purchase because the first one failed after 3 years. Not sure if it was defective or 3 years is the lifespand of this product. But since the cost is low, is was not a big deal to order a new one...16602

I found two grommets I could remove on my MDX, slit each down the middle and then run the harness through so I didn't have to run the harness out the hatch AND no splicing of the harness at all. Bonus. 12240
