CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Acura MDX (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

I would have rather paid a couple more dollars for this kit and have it come with everything that's needed. I was disappointed when I opened the box and found that it did not include four additional fuses needed to make this work: two 7.5A and two 20A mini-fuses. Thankfully, Amazon's overnight delivery pulled through and I was able to buy an assortment of fuses that got to me before my trailer rental appointment.As far as the harness itself, it works flawlessly and the installation took less than 15 minutes.

Quick and easy to install. I took the extra time to feed the line to the rear of the vehicle through a rubber plug in the floor pan. I ran the wiring along the same path as the main wiring harness for the car from the vehicles rear electoral junction box.

This takes the worry out of wiring up the trailer connections. Worth the money and Curt is a product youcan depend on. No issues.

Fits in the slot (Acura MDX 09), the cable is long enough, it seems robust enough. It gave me a chance to clean under my SUV's carpet!

I bought this because I didn't want to "hack" my factory wiring harness to add a 4 pin trailer wiring harness. The factory options where very expensive of course. This unit plugs directly into the factory wiring harness in the back of the MDX. All you need to do besides plug it in is connect the grounding wire to one of the easily accessible bolts near where it plugs in. Install took me literally 5 minutes and it is working perfectly.What I like about this versus "hacking" into the stock wiring harness is the trailer lights only work when the vehicle is running. Which is how it should be since the additional power draw could drain the battery unnecessarily when the vehicle isn't running.I am still amazed how easy it was to install this. I am very rarely impressed with aftermarket products but this one definitely impressed me. If you have a MDX and want a trailer wiring harness I can't recommend this enough. So simple to install and it works!

Used this connector for wiring up my '09 MDX with a Class 4 receiver. It's simply a plug & play installation - pull off the drivers side interior trim panels and plug into the electrical panel at the back of the vehicle. You'll need to use a self tapping screw to ground the wiring but there's a number of places under the trim to do this. You'll find three or four rubber plugs on the back body panel (where the liftgate latch is) that will accommodate the wire pass though and another rubber plug on the exterior to get the wire outside the vehicle (remove the spare tire first for easy access). Use some silicone to seal the plugs and secure the wires and you're done. Too easy.

The wire harness was easy to connect up to my 2011 MDX. Just plug it into the fuse box located on the back left side and it’s pretty much ready to go. In the instruction, they wanted you to just leave the harness hanging out of back door hatch when in use and stow away in the back compartment when not in use. It doesn’t look very professional with wires hanging out the back door. What I did to keep all the wires hidden was route the wires thru existing manufacture pre-cut holes. There are also pre-cut holes to run your wire harness to the underside of the vehicle. To expose these pre-cut holes, you will have to remove the compartment door and carpet and also the plastic molding, (see pictures). There is also an existing bolt there that you can connect your ground to. These pre-cut holes has rubber cap covering them that you can pop off easily. I used these rubber caps and run my harness thru them to protect the wires from the sharp edges of the pre-cut hole. To run my harness thru the rubber cap, I had to cut a round hole out of the middle of the rubber cap and cut thru one side of the rubber cap then run my wires thru it. I used Duct Tape to give it a snug fit around the rubber hole. I also wrapped the wire with Duct Tape wherever it comes in contact with sharp metal edges. I hope this helps.Update 8/14/15I ordered a mounting bracket, CURT 58001 which give it a cleaner look. No more zip ties.
