• Will the Pro Series Trailer Hitch Mounted Cargo Carrier Fit a 2008 Acura MDX
  On the trailer hitches we have installed on a 2008 Acura MDX and similar models, we have found that the distance from the center of the hitch pin hole to clear the rear bumper on the vehicle measures up to 5 inches. The Pro Series Cargo carrier, # 63153, measures 12-3/4 inches from the center of the hitch pin hole to the nearest edge of the carrier so it will clear the rear bumper. This is also enough distance to allow you to open the rear hatch on the vehicle. If your tail lights are...

• 7-Way and Brake Controller Recommendation for 2010 Acura MDX
  You will need to start with a 4-way (if you do not have one) on your 2010 Acura MDX to install a 7-way and brake controller. For that you would want the # 118424. 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 video for this product as well. For a brake controller I would recommend the Prodigy...

• Can Tow Ready # 118265 For 2012 Honda Pilot Be Installed on 2012 Acura MDX
  The wiring systems of the 2012 Pilot and Acura MDX are different enough that the # 118265 isn't a fit for the MDX. The procedure for installing a 7-way on your MDX wouldn't be as simple but it could certainly be done. The Pilot and MDX are fairly closely related, but not so close that the two would interchange tow package elements. You'd begin by installing a 4-pole trailer connector using part # 118424. How you'd proceed from there would depend on your trailer. If your trailer doesn't...

• Recommended Trailer Hitch and Wiring for 2012 Acura MDX
  Thanks so much for your repeat business! Starting with the trailer hitch itself, the Curt Class III Round Tube Receiver Hitch # 13354 that you referenced is confirmed to fit your 2012 Acura MDX and will work great. The hitch is custom-fit for the vehicle, so it will use existing holes in its frame for a no-drill installation. I have attached an installation video on your Acura that you can use for reference. Then for a custom-fit wiring harness, I recommend the Tekonsha T-One Vehicle...

• Trailer Lights Work then Shut Off Using Wiring Harness 118424 on a 2012 Acura MDX
  You should not require additional fuses or relays to install the trailer wiring harness # 118424 unless those items are missing on your 2012 Acura MDX. In some cases, there is a relay needed that can only be obtained at an Acura dealer. Consult the vehicle owners manual for the locations of any fuses or relays related to the trailer wiring to check them. The fact that it worked at first then stopped tells me that it could still be a ground issue. You can try moving the converter ground...

• 2011 Acura MDX Trailer Wiring Harness Recommendation that Does Not Require any Relays
  For trailer wiring for your 2011 Acura MDX we have the Draw Tite harness part # 118424 which does not require any special relays from Acura. It comes with everything needed to install and would work well for you. I attached an install video for this harness on a 2011 MDX just like yours. The Curt harness wouldn't require the relay either, but since we have better luck with the Tow Ready harnesses I recommend them more.

• How To Connect a 5-Way Trailer Connector To a 4-Way Vehicle Connector on a 2007 Acura MDX
  You are correct, the 5th pin on the 5-pin connector is to provide the reverse lockout feature for surge brakes on the trailer. It will have to tap into the reverse light circuit of your vehicle to operate properly. We have a part that is designed just for that purpose. It is the Tow Ready 4 Pole to 5 Pole Wiring Adapter, part # 20036. This adapter will plug into the 4-Way connector on your 2007 Acura MDX and the extra blue wire would be spliced into the reverse light circuit on your vehicle....

• Trailer Hitch, Cargo Carrier and Carrier Lighting Kit for Use on 2007 Acura MDX
  The 2-inch Class III trailer hitch that you referenced, Curt # 13354, offers a substantial 500-lb tongue weight capacity which makes it great for use with a compatible Class III cargo carrier like the ProSeries # 63153. I have linked an install video for this hitch on your same exact vehicle. This hitch-mount carrier also offers a 500-lb capacity but it is suggested that you check your MDX owner's manual to verify what the vehicle's tongue weight rating is, since it could be lower than...

• Adding a 5-Way Flat Trailer Connector to a 2011 Acura MDX
  All of the trailer wiring harnesses for the 2011 Acura MDX have 4-Way flat connectors. In order to have a functioning 5-Way you would first install a 4-Way such as # C56038, # 118424, or # HM11143275 (they all install the same way) and then use a 4- to 5-Way adapter, # 20036, like you said. I have linked some videos to help with installation.

• Trailer Wiring Harness Shows No Power On 2010 Acura MDX
  When installing the Tow Ready Wiring Harness, part # 118424, and you find that you have no power to the wiring harness you probably need the relay as stated on our site under Tech tips. You will need to visit your Acura dealership to have the relay installed. They would be able to advise you concerning the best location for installation. One of our folks here said that most Acuras have the relay installed but on occasion it has not been there and requires the dealer to take care of it.

• 2007 Acura Mdx Trailer Light Relay Location
  For your 2007 Acura MDX, when installing a wiring harness like the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118424 a trailer relay from the manufacturer may be needed. Once obtained the trailer relay location is under the rear fuse panel in the cargo area on the drivers side. It will be below and slightly to the rear of that fuse box access. You will also want to make sure your trailer fuse is good under the hood of your vehicle.

• Troubleshooting Brake Lights on Trailer Towed by 2008 Acura MDX
  I'd be happy to help you with that. You'll need a circuit tester like part # PTW2993. Check the pins that are fed by the green and yellow wire, there should be signal on those wires with the brake pedal pressed. If you don't see power on either of those wires with the brake pedal pressed, trace the 4-pole trailer connector until you reach the black converter box. Locate the red wire entering the converter box. Test the red wire, which SHOULD show power when the brake is pressed. If it does...

• How to Route Trailer Wiring Permanently to the Outside of a 2013 Acura MDX
  The Draw-Tite trailer hitch # 75614 for your 2013 Acura MDX is now the only option that comes with the mounting location for a 4-Way mounting bracket. Hidden Hitch has been discontinued. In addition to the hitch and the wiring you will also need bracket # 18144. For wiring harness # 118424 or any of the wiring harnesses for the vehicle you can route the 4-Way through the vehicle and outside to attach it to the bracket rather than storing the harness in the vehicle when not in use.

• Recommended Hitch for a 2011 Acura MDX
  To install a trailer hitch on your 2011 Acura MDX you are going to want the etrailer Trailer Hitch Receiver item # e26AR. This hitch is custom fit and bolts to your Acura with included hardware. It has a matte black powder coat finish that not only protects your hitch but also helps to conceal it unlike other hitches with glossy finishes. This hitch does not fit models with rear Sport Bumper trim. If you are going to tow with this hitch you will need a wiring harness item # 118424 and...

• Is Custom 4-Way Trailer Wiring Harness 118424 Better than Curt Wiring Harness 56038 for an Acura MDX
  Both the Tow Ready wiring # 118424 and Curt wiring # C56038 are correct fits for the Acura MDX, but the # 118424 is a confirmed fit for more model years. The # 118424 will fit 2007 through 2010 MDX models, while the # C56038 is only confirmed to fit 2007 through 2008 models. Both wiring harnesses plug in at the same factory port, as they are both custom fit for the vehicle, and both feature a powered converter to protect the MDX electrical system.

• Trailer Hitch, Ball Mount, Ball, and Trailer Wiring Recommendation for a 2007 Acura MDX
  You are correct that the trailer hitches for a 2007 Acura MDX are all very similar. All of them have a 400 pound tongue weight capacity and 4,000 pound gross trailer weight capacity. All can be used with weight distribution to bring the capacity of the hitch up to 500/5,000 pounds. And all of them install in much the same way with an estimated installation time of 30 minutes. Really, all of the companies make their hitches to meet or exceed the standards of the department of transportation....

• Parts Needed to Add a 7-Way and Trailer Brake Controller On a 2012 Acura MDX
  We do have all the parts you will need to install a 7-way on your 2012 Acura MDX but currently there is only a custom fit 4-Way # 118424. The Universal Installation Kit # ETBC7 will allow you to install a trailer brake controller inside the cab of your MDX or you can use a wireless controller like the Curt Echo # C51180 with adding the 7-Way RV Upgrade Kit # ETBC7L. For an in cab controller I recommend the Redarc Tow-Pro Liberty Brake Controller # RED52VR as it has a small control knob...

  To attach wiring harness # 118424 to the hitch you can use a different type of mounting bracket that does not require screwing into the plastic fascia. You can install the wiring harness like in the video I have linked and then use the 4-Flat Mounting Bracket, # 18144 which will attach to the hitch.

• How to Tap Into the Reverse Light Circuit of a 2007 Acura MDX for Installing a 5-Way
  If you open the liftgate of your 2007 Acura MDX you should see a black section of conduit that holds wires that will run from the threshold of the door to the door itself. In that bundle of wires should be a reverse light circuit. What you could do is remove the interior panel behind the threshold where the harness goes and test the wires to find which one is the reverse light circuit. You will need to use a circuit tester like our part # PTW2993. Aside from that you could try tapping...

  Curt trailer hitch # 13354 is listed as compatible with models of the 2009 Acura MDX that have the full size spare tire. I have included a link to a video showing an example installation for you. If you plan on doing some towing I 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, 2 inch ball, hitch pin with clip, and a storage bag. If the ball...

• Recommendation for Brake Controller and Wiring for 2007 Acura MDX without Tow Package
  It sounds like your MDX doesn't have the factory tow package, if the 7-way controller isn't mounted to the back of the vehicle. The good news is that I can help you outfit your 2007 Acura MDX for a 7-way and brake controller. Since the vehicle isn't already prewired for a 7-way, you will need to hardwire the vehicle. You will not need the adapter because the brake controller will include a universal harness. To equip your vehicle with a 7-way you will need the 4-way # 118424 and the...

The issue that you are experiencing with the trailer lights not working when the vehicle ignition off or the key in the off position is attributed to the vehicle wiring.
