• Troubleshooting Curt Vehicle Wiring Harness 56083 On 2021 Lexus RX 350 Not Having Power
• The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # 56083 requires your 2021 Lexus RX 350 to have the factory tow package which includes a factory installed module to power the trailer lights. Since your harness does not have power I recommend checking that there is a module plugged into the 10 pin connector which may be inside the luggage compartment, on the passenger side below taillight, behind little plastic removable bin. If no module is plugged in you will need...

• Troubleshooting LED Tail Lights On U-Haul Trailer Dim With Tekonsha 118255 On 2016 Lexus RX 350
• When a harness like the Tekonsha T-One Vehicle Wiring Harness # 118255 on your 2016 Lexus RX 350 is causing the lights on a trailer to be dim, it is usually a ground issue. Since your harness does not have a ground wire that you need to ground to the frame, I recommend checking all of the connectors on the harness to make sure they are fully seated in the vehicle connectors. If they are fully seated then remove them and look inside the connectors to see if any debris go in, or if there...

• Why Would Trailer Hitch Install Cause Muffler Noise
• Exhaust rattling against a trailer hitch is a common occurrence but it is easily fixed. Exhaust pipes and mufflers hang on rubber isolators. The hangers can usually be manipulated to gain more clearance between the exhaust and the hitch. I have included a link below that covers the different fixes for this problem.

• Troubleshooting Trailer Brake Lights Not Working
• I would start by testing the trailer wiring harness, # 118652, you just installed on your 2017 Lexus NX200t. Use a circuit tester like # 3808 and test each function. If the problem is on the vehicle then check for any fuses related to trailer brake lights. If it's not a fuse you'll need to check the wiring connections you made when installing the harness. If everything checks out at the 4-way trailer connector then the problem is on the trailer. Inspect the trailer's 4-way and make...

• Hybrid Error on Lexus After Installing Curt T-Connector
• For your 2012 Lexus CT 200h, if you are seeing a check hybrid system error after installing the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 56099, based on some googling of that error code it is likely the issue is related to the battery wire. Make sure it's attached to the positive terminal of the battery securely and no exposed wire on this circuit is making contact to anything metal. It's also possible the battery terminal wasn't tightened all the way...

• New Trailer LED Tail Lights Do Not Light Up with Running lights on 2011 Lexus IS 250
• It sounds like there could be a ground problem. A weak ground could cause this issue. Different vehicles also have different power capabilities so testing with another vehicle does not always indicate where the problem is. What you will want to do is test the vehicle without the trailer connected. You are going to need a meter to test the voltage on the trailer wiring harness on your Lexus. If you need a meter we have # PT89ZR. First, test the running light wire going into the converter...

• Trailer Wiring Harness # 118252 Not Working on a 2012 Lexus RX 350
• The trailer wiring harness, # 118252, is for a 2012 Lexus RX 350 that came with a factory tow package. It sounds like your RX 350 does not have the factory tow package so you would need to use trailer wiring harness # 118478. If your vehicle is supposed to have the factory tow package (have the dealer run the VIN to determine if it does or does not have the tow package) then the missing components to make it active could be obtained through a dealer. I have included a link to the installation...

• Trouble Switching from Highway to City Braking with Redarc Brake Controller on 2011 Lexus GX 460
• If you're having issue with braking adjustments on your Redarc Tow-Pro Elite Brake Controller part # RED44FR, I first recommend finding a new spot for the main unit. The main unit needs to be attached to a solid surface, without movement. The main unit houses the inertia sensor so if it's not solid and moving around, it could very well contribute to unpredictable braking. If this doesn't help, unplug the controller so you can allow it to reset, then recalibrate the unit. The purple light...

• Thule Helium Platform # TH44VR Leans To One Side When I Install It Into My Hitch
• When you put the Helium Pro # TH44VR in the hitch, get the pin in place then tilt it right to left as you tighten the hand knob at the bottom. It seems like you don't have the knob tightened down all the way. You can see what I mean in the video I've included for you. Right at the beginning of the video I do exactly this and it does not learn like yours is. I've used this on many many vehicles in the past and never had this issue when it was secured properly. If this doesn't solve the...

• Thule Sidearm Ratcheting Arm Will Not Stay Locked
• This is the first time I have heard of this issue on the Thule Sidearm. The first thing I recommend checking is that the locks are seated all the way into the housing. Use the change key, # 853-1251 if you need it, to pull the locks out and put them back in. There also could be damage to the mechanism which could occur if someone tried to turn the lock beyond its natural positions, used excessive force, or if some crud got in there and gummed up the works. Similarly, if the arm was pushed...

• Troubleshooting Blown Tail Light Fuses with a Non-Powered Tail Light Harness on a 1999 Lexus RX300
• Sounds like your trailer is overdrawing your tail light circuits and that is why the fuses are getting blown. Having a powered unit does make a big difference for this issue. A powered unit will basically only use the tail light wiring as signal wires and then draws all the power for the trailer tail lights directly from the battery. This protects the delicate tail light wiring and prevents problems like what you are experiencing. I think your best option at this point would be to install...

• No Lights On Trailer When Using Curt Wiring Harness # 56083 On 2010 Lexus RX350 Without Tow Package
• On your 2010 Lexus RX350 without a tow package, you would need to use Tow Ready Custom Fit Vehicle Wiring, # 118478. I have included a link to the installation details below. This harness includes a circuit protected converter and requires a direct connection to the battery. This connection to the battery virtually eliminates power draw from the vehicles taillights, which protects the sensitive wiring. The Curt T-Connector Vehicle Wiring Harness with 4 Pole Connector, part # 56083 is for...

• Troubleshooting Installation of Tekonsha Wiring Harness 10-Pin Connector on 2019 Lexus RX 350
• Aside from what you already found, the best advice I can offer comes from another customer who installed the # 118255 on an RX 350. On the inside corner cover, pry up the center of the black plastic fastener and remove it. Reach under the cover with small pliers and squeeze a hidden second fastener's prongs to pop the cover loose. The white connector for the 10 pin adapter will have a black rubber sheath. It is located slightly up and out of sight toward the rear of the vehicle. I'm not...

• Troubleshooting 4-Pole Wiring Harness on 2003 Lexus RX300
• Tekonsha 4-pole wiring kit # 118245 is the correct OEM replacement harness for the 2003 Lexus RX300 with factory tow package. If you checked the fuse and tested the pins on the 4-pole plug and have no power on any of the 3 circuits I suggest you unplug the harness and test the OEM connector on the vehicle where this part plugs in. If you have signals there, upstream of the 4-pole harness, then the harness may be bad. If you do not have signals there then there may be an issue within the...

• What Can I Do When My Hitch Bike Rack Interferes With My Brake Sesnor
• Unfortunately, there is not a long term fix for this issue. Your 2017 Lexus RX 350 views your RockyMounts WestSlope 3 Bike Rack - 2" Hitches - Tilting - Wheel Mount, part # RKY10223, as an obstacle, especially when loaded with bikes. Your only solution is to disable the sensor while you are using the bike rack. You should still have use of the rear mounted camera, but you will not have use of the cars backup sensor while the bike rack is in use.

• Trailer Lights Not Working After Installing Wiring Harness on a 2015 Lexus RX 350
• First, the trailer wiring harness # 56083 is only a fit if your 2015 Lexus RX 350 came with the factory tow package. If it did not then that could be why it isn't working. Or, if it does have the factory tow package, it could be a missing fuse or relay which you could find in the under hood fuse panel or the in cab fuse panel.

• Troubleshooting Locking Clamps That Won't Move on the Thule EasyFold XT Bike Rack
• I see you asked this question from the Thule EasyFold XT Bike Rack for 2 Electric Bikes # TH903202 so I am assuming you are talking about the padded clamps with hand knobs that come on this rack. Those clamps are designed to free spin when locked, you can spin it over and over and it will not loosen the clamps. It sounds like you have unlocked the clamps but are unable to get them to spin to loosen the clamps. If that is the case you can try locking and turning, then unlocking and turning,...

• Troubleshooting New Trailer Plug Not Working for 2021 Lexus RX 350
• I'm not sure what wiring you purchased but if it's anything like the Curt T-Connector # C56217 for a 2021 Lexus RX 350 without the tow package then the system should be working once you get the module and fuse installed. If you aren't seeing power to the fuse then I recommend using your tester on the OEM plug pins to see if you find power anywhere there. If you still can't find any power I recommend taking your vehicle to your local Lexus dealer to have them look at your OEM wiring. It's...

• Troubleshooting Bike Mount Issues on the Kuat Beta Bike Rack on a 2011 Lexus CT 200h
• I think I have a solution to your problem. I would recommend you use a bike adapter bar like the Thule Bike Adapter Bar for Womens and Alternative Bike Frames, part # TH982XT. A bike adapter bar is specifically designed to help you carry bikes that have odd or smaller shaped frames safely on a bike rack. The adapter bar will attach to your bikes seat post and the handle bar post. I have attached a video showing how this adapter bar works for you to check out.
