• Ultimate Trailer Jack 322-RDJ-2K Stuck And Won't Go Up Or Down
• There are a few things you can do to troubleshoot your Ultimate Trailer Jack # 322-RDJ-2K, start by loosening the 3 mounting bolts used to attach to your A-frame. From here you will want to check for movement. If it does move, tighten the bolts back up by hand at first and check again for movement. If all is good, tighten the mounting bolts back down to spec by alternating each bolt to ensure not one bolt is being tightened more than the other. If that doesn't work, you can also try loosening...

• No Signal or Function on Trailer Harness on a 2007 Acura MDX
• As far as I can tell, one of two things has happened. Either the tow wiring fuse has blown or the Modulite box on the harness has burned up. A short on the trailer could cause either of these and both would lead to no signals at the connector. I will walk you through a process to diagnose which is the root of the problem. Using a circuit tester, like part # PTW2993, go to the back of the vehicle where the harness is attached. Un-plug the trailer harness and check the pins on the vehicle...

• Trailer Lights Not Functioning if 2013 Acura MDX Key is not in On Position or Running
• The Draw-Tite T-One Vehicle Wiring Harness with 4-pole flat trailer connector # 118424 plugs directly into the vehicle established wiring harness using the T-one style connection at the fuse box located in the cargo area at the rear of the vehicle. 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. It is most likely a function of how the vehicle itself is wired and does...

• 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...

• Troubleshooting Smudge from Yates Bow Stop
• Since your Yates Y-Style Bow Stop # YR4Y22-3 leaves a smudge mark, you can use marine grade bunk carpet like # FCR8008 in between to assist. There isn't a glue specifically made for that type of application so I recommend using a solvent based contact cement. There are some non-marking bow stops, but the Yates Y-Style Bow Stop for Boat Trailers - TPR - 6-1/2" Span - 1/2" Shaft - Yellow # YR333Y isn't just an easy swap.

• Troubleshooting Function Issues With Tekonsha Trailer Wiring Harness # 118336
• The Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118336 is a confirmed fit for your 2005 Acura MDX. I recommend using a circuit tester like # PTW2993 to troubleshoot. I recommend testing each function at the end of your 4-way connection. If they are working, then the issue is most likely with the ground wire on your trailers. If they are not working then you will want to test the individual functions on either side of the box. If the result is consistent,...

• Troubleshooting 4-Pole Installation in 2007 Acura MDX Towing Pop-Up Camper Trailer
• If two separate wiring harnesses installed in your 2007 Acura MDX have both failed after being connected to the same trailer, then I suggest you carefully check the trailer for problems like shorts and damaged insulation in its wiring. This type of harness is intended to take the hit from such a trailer fault rather than allow it to damage the car's delicate (and costly-to-replace) internal wiring. A new trailer harness is a lot cheaper and easier to install than new vehicle wiring, but...

• Muffler Hits Receiver Hitch on a Acura MDX 2004
• I have linked a picture from below to show you how the Draw-Tite Max-Frame Trailer Hitch Receiver item # 75599 you referenced is suppose to look when installed on a 2004 Acura MDX. I would check to make sure your muffler and exhaust hasn't been bent or damaged in a way that would cause it to rub on the hitch. I have also linked the instructions and a video of the installation process so you can verify the hitch has been correctly installed.

• Is a Relay Required to Activate Trailer Wiring Harness # 118424 on a 2010 Acura MDX
• Tow Ready trailer wiring harness # 118424 is a fit for your 2010 Acura MDX. You will need to make sure that the white ground wire is attached to a clean and corrosion free bare metal surface. A weak ground connection could be the cause of the problem. It is also possible that you will need a relay. Most of the vehicles that use this harness have the relay but if yours is missing the harness will not be fully functional. You can check to see if yours is present by finding its location using...

• Lock Sticking on Thule T2 Pro
• If your key on your Thule T2 Pro # TH83JV is not turning I recommend that you works some lubricant like the LubriMatic White Lithium Grease # L11354 into the lock. This works to penetrate through any corrosion and loosen the locking mechanism and allow you to get the key to turn. I particularly like this product more than something like WD-40 because it's biobased, so it's non-toxic and safe to use around the house. If you continue to have issues with the lock core, it might be time to...

• Trailer Brakes Lock Up When Connected to a 2016 Acura MDX
• If electric trailer brakes lock up as soon as the trailer is connected to the tow vehicle that is an indication that something is pinned out wrong or there is a short somewhere. We usually see this problem when someone is using a 7-Way to 6-Way adapter such as # 47549. There are 2 ways that a 6-Way can be wired. The center pin will be either 12 volt power or electric brakes. If the trailer side connector is wired opposite of how the adapter is wired then the brakes will receive 12 volts...

• Redarc Tow-Pro Elite Not Calibrating On 2012 Acura MDX
• A blinking blue light after the manual override is pressed on your Redarc Tow-Pro Elite # RED44FR can mean a couple different things. This may mean the remote head cable may have been damaged. You should check the cable between the remote head and the main unit and inspect for damages. It also may mean the red wire is constantly at low voltage, check voltage to the red wire and reassess the connection point if necessary. Additionally, you should not be receiving voltage on the blue wire...

• Can a Timbren Rear Suspension Enhancement System Eliminate Vibration in a 2008 Acura MDX
• Once the Timbren Rear Suspension Enhancement System, item # THROD2, is installed on the 2008 Acura MDX, the Aeon hollow rubber springs will not contact the bottom of the coil spring housing unless there is a load on or in the back of the vehicle, see installation instructions link below. This means that if the vibration you are referring to is present under normal operating conditions, not towing or carrying a load, the rubber springs will not help. In this case, I would have the vehicle...

• Troubleshooting 7-Way Wiring Installation on 2017 Acura MDX
• The Tekonsha T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118289 is confirmed to fit your 2017 Acura MDX. This fits all models so it is not a matter of your vehicle not being supported. You are correct, you won't get anything on the blue wire for the brakes without a brake controller like the # RED44FR. The black 12V power should be working if properly installed. Since you already have a tester, try testing the wire behind the end of the connector. It is possible the wire...

• Troubleshooting Overstuffed Yakima SkyBox Not Opening
• If the front arm/hinge on your Yakima SkyBox Cargo Box like the SkyBox 12 # Y07334 isn't unhooking due to the carrier being over-stuffed, then your only real option is to try and wiggle around your cargo enough to get some clearance between it and the arm. Since you're able to release the back hinge you should hopefully be able to open the box just enough to slide something inside to maybe move some of your belongings around to try and disengage that front hinge to open the box fully. It's...

• 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...

• Trailer Wiring Harness Installation on 2015 Acura MDX
• I'm sorry that happened. According to Tekonsha, they haven't changed the plug used on their 4 pole trailer connectors in many years, so I suppose it's possible that either the drain hole diameter might not be consistent across the vehicle line or there might be another larger opening in the floor pan. What I'd do in your situation is use a rotary tool like a Dremel to notch one edge of the hole just enough so you can slip the trailer connector through. Reinstall the plug using silicone...

• Troubleshooting LED Identification Light Bar With Lenses Easily Knocked Off
• The LED Identification Light Bar for Trailers over 80" Wide - Submersible - 9 Diodes - Red Lens # MCL93RB has the wiring and housing for the individual sealed lights # AL91RB to fit. The only way to help them stay in place a little better is to add silicone around the edges to just add an additional seal that will hold up to vibration and water. An alternative option is to use the LED Identification Light for Trailers Over 80" Wide - 3 Diode - Sealed - Rectangular - Red # MCL98RB which...

• Do I Have To Relocate My Hands Free Sensor If I Install The Draw-Tite Hitch Receiver
• Yes, you might have to relocate the sensor. Typically relocating the sensor is not a problem on the MDX. My recommendation would be to install the trailer hitch, the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class IV - 2", part # DT42MR, and test the hands free liftgate. If it works to your satisfaction, you do not have to change anything. We have had customers, and employees, have luck kicking their foot to the right or left of center to activate the hands free liftgate....

• Which is Better For Down Hill Braking, a Auto Leveling Proportional Controller or a Manual Level
• The accelerometer of the Prodigy P3 Brake Controller part # 90195 is the sensor that can sense changes in inertia and tell the brake controller how much braking power to apply to the trailer's brakes. It can do this on multiple axis and that is why it does not require leveling. When you introduce hills into the scenario any proportional controller will behave slightly different. A manual level controller will still not sense the deceleration perfectly since the change in incline can't...
