• No power on the 4-Way Trailer Connector # 118491 on a 2009 Honda Pilot
• What I recommend is to remove everything that came with the Tow Ready wiring harness, # 118491, and then start the installation again as if it was the first time. It could be that you missed something and that by going through the steps again will reveal the issue. Once you have everything except the 4-Way part re-installed, use a circuit tester like # PTW2993 if needed and test the connector on the vehicle where the 4-Way installs. If you still do not get any power when the brakes are...

• Hopkins Agility Trailer Brake Controller # HM47295 Has Small Dot Light Always On
• I spoke with my technical contact at Hopkins and it sounds like two wires may have gotten switched around during the installation of the Agility Trailer Brake Controller # HM47295. I recommend double checking your connections by testing the wires for function with a circuit tester, like part # PTW2993. From the information that I was able to obtain on the 2014 Honda Odyssey, this will most likely be your wiring combination: White wire on brake controller to black wire on Odyssey for...

• Troubleshooting Trailer Taillights that Have Power but Do Not Function
• Are you referring to the trailer wiring kit you bought from us or the trailer lights I see that you ordered at same time? I would assume it's the light kit part # TL29BK which since you tested and the lights have power ran to them that would indicate the issue is the ground circuit. These ground through the mounting hardware so make sure they are mounted to a clean metal surface. If you tested them before mounting them that would be why they aren't functioning since they wouldn't be grounded.

• Which Wires To Re-Connect 4-Way Flat Vehicle and Trailer Connector
• On the 4-way connector, Green will be right turn and brake, Yellow is left turn and brake, Brown is tail or marker lights, and White is ground connection. If you need to replace the trailer side connector, you will need 4-Pole Trailer End Connector, part # 18004. If you need to replace the vehicle side connector, you will need Tow Ready Wiring 4-Pole, part # 18002. You will use the included connectors and connect the wires color for color. I have linked an FAQ on wiring the shows the...

• Troubleshooting Trailer Right Turn Signal And Right Brake Light Not Working On 2019 Honda Odyssey
• It would seem odd that you would receive 2 defective Curt T-Connector Vehicle Wiring Harnesses # C56382 for your 2019 Honda Odyssey. The first place I would like to start is at the 4-way connector. A Test Light # PTW2993 is the best way to check the wiring. First check all the connections ends for power when the corresponding function is active, and for any that do not have power move up the connector and check the wire for power going into the connector. The female terminal on the end...

• Left Tail Light on Trailer Towed By 2009 Honda Pilot not Working
• As a first step, you will need to determine if the wiring problem exists on the vehicle or on the trailer itself. Unplug the trailer, and use a circuit tester like part # 40376 on the 4-pole on the vehicle while each function is activated. The pin fed by the yellow wire should show power when the left turn signal or brake is activated. The pin fed by the green wire should show power when the right turn signal or brake is activated. The pin fed by the brown wire should show power when...

• Troubleshooting Trailer Turn Signals that Both Blink When One is Applied
• Sounds like the left and right stop/turn circuits are shorting out to each other somewhere. Typically this is a corrosion issue or cut or exposed wire. You will want to start at the connector looking for corrosion or bent pins and work your way to the wiring looking for cut or exposed wire making your way back to the light assemblies. I attached a help article on troubleshooting trailer wiring for you to check out as well.

• Troubleshooting Trailer Lights not Working with 2009 Honda Pilot
• This is an issue we run in to quite commonly when installing Combination LED Trailer Tail Light part # STL9RB or any other trailer light. The good news it has nothing to do with the vehicle 99% of the time. The most common cause for this is bad grounding at your lights or at the wiring harness ground. When this came into the shop my first step would be to remove sand down to good steel and replace each ground. That will likely solve your issue. The very dim light coming through is an indication...

• Troubleshooting Turn Signals of Trailer Wiring on 2009 Honda Pilot Not Working
• You did quite a bit of troubleshooting and homework on this so I commend you for that! Since it's not the relays, the fuses, or the trailer wiring that basically leaves the converter box of the wiring kit. Which you can test that with a circuit tester like part # PTW2993 by checking for voltage when the turn signals are on going into the box and then check to see if they are making it to the output side. If there's none making it to output side the box is bad and would need to be replaced...

• Troubleshooting Yakima OnRamp Bike Rack Movement While Driving with a 2012 Honda Crosstour
• Thank you for reaching out and your purchase of the Yakima OnRamp Bike Rack for 2 Electric Bikes - 1-1/4" Hitches # Y96FR. Using a stabilizing strap can help keep the rack from moving around as much so if that's the route you want to take then I recommend using the Curt Cam Buckle Stabilizing Strap # 18050 which can be secured to your trunk/hatch or safety chain loops - whichever is easiest to then extend the strap to the bike rack. With that being said, the reason why you're experiencing...

• Troubleshooting Honda Ridgeline Blinkers that Stop Working when Brakes are Applied
• Typically when this issue arises on a Honda Ridgeline the issue is that the "small lights" fuse under the hood is blown. This may or may not have been related to the trailer wiring you installed.

• How To Gain Access To A Pop & Lock Tailgate Lock When You Have A Tonneau Cover In The Way
• Since you have a cover it's going to be a bit harder to gain access and open the tailgate. You can try to see if you can get your hand under the cover since there should be a bulb seal at the tailgate that you could probably get your hand in through and unlatch the cover to get access to the inside of the tailgate. You could also try removing the trim panel around the tailgate handle and seeing if there's enough access with it removed to get your fingers in there an actuate the lock yourself....

• Troubleshooting Left Turn Signal/Brake Light Not Working On 2014 Honda Pilot
• It sounds like either the tester might have a faulty indicator or you are not getting power to the left turn/brake wire. A Test Light # PTW2992 would help to determine if this circuit went bad on your tester or the issue is in the vehicle. If you still have no power to the left turn/brake you will want to inspect the connectors through the harness to ensure that there are no missing/damaged pins inside a connector or a damaged fuse/relay. The weak brake circuit light is normal with a...

• What to Check for When Troubleshooting Trailer Tow Harness on a 2013 Honda Pilot
• Troubleshooting wiring can be frustrating because even the smallest thing can cause issues. Here's what you'll need to check: - All connections for problem circuit - All grounds for problem circuit - Vehicle side connector - Trailer side connector - Fuses and relays - Wiring going into and coming out of module box (black box included with T-One # 118265) - No bends, breaks, or exposed wiring Knowing which end of the towing setup the issue is on (vehicle or trailer) helps to isolate...

• Troubleshooting Trailer Error When Using Curt Echo Under-Dash Controller on 2020 Honda Ridgeline
• Thank you for all of the info! The Curt Echo Wireless Trailer Brake Controller # C51180 just requires the trailer lights and 12V power pin to operate properly but the Curt Echo Under-Dash Trailer Brake Controller # C27JR and Custom Wiring Adapter # C51392 require your 2020 Honda Ridgeline to have the tow package so all of the wiring exists on your 7-Way - especially the brake control pin in the 5 o'clock position (see attached). If you grab a tester and put it on that pin and then apply...

• Troubleshooting Installation of Curt Wiring Harness on 2013 Honda Accord Seda Without LED Taillights
• Since it looks like you have the 2013 Honda Accord Sedan without LED taillights the first thing you should do is make sure you have the correct wiring harness. If that is correct, then you will need the # C56011 instead of the # C56173. When installing the wiring harness on that side you will use the yellow T-connector for the top plug and the red one for the bottom plug. Assuming you have the correct wiring harness the two plugs from your picture should have no problem fitting. I have...

• Trailer Lights Stopped Working on Wiring Harness # 118558 for 2013 Honda Pilot
• Thank you for your September 2013 purchase of trailer wiring harness kit # 118558 for your 2013 Honda Pilot. First, check that all of the relays are inserted properly in the harness and the fuse you installed in the engine compartment is still okay. You can also unplug the relays and connectors to inspect the condition of the contacts, looking for any dirt, potential corrosion from moisture or any other visible condition that could explain the non-functioning stop/turn lights. If your...

• One Nev-R-Adjust Trailer Brake Assembly is Very Tight Even After Loosening the Brakes
• Is it possible that the drum is slightly smaller than the one on the other side? This does not seem likely but it might be worth measuring them on the insides to see. Adjusting self adjusting brakes is actually a little more difficult than you might think. If you were able to turn the adjustment wheel to back off the shoes and you have reached as far as it will go, try giving the shoes a little inward push. It is possible that they are stiff or need lubrication (careful not to get any...

• 7-Way Trailer Wiring Harness Stopped Working On a 2011 Honda Pilot
• The first thing I recommend doing is checking the vehicle side connector for dirt and corrosion build up at the 4-Way. I had a friend that had this problem. The 4-Way had enough corrosion in it to cause the lights not to work. After clearing it out, it worked fine. You could use a circuit tester such as # PTW2993 if you do not have one to test the wires at the back of the 4-Way to determine if the signal is getting through to that point. That would confirm a problem with the plug, most...

• Trailer Tail Lights Not Working after Installing Tow Ready Wiring # 118491 on a 2010 Honda Pilot
• Thank you for advising the troubleshooting steps you have taken. Installation of this trailer wiring harness # 118491 in your 2010 Honda Pilot requires you to insert components in four separate locations within the vehicle. The 4-pole wiring connects to the plug under the rear bumper; the 3 flat fuses and relay are to be installed in the forward of the two driver-side compartments (the one labelled Aux Fuse); the black box plugs into the harness behind the larger rear driver-side compartment;...
