• Troubleshooting Hopkins Plug-In Connector Not Working on 2003 Lexus GX 470
• The Hopkins Plug-In Simple Vehicle Wiring Harness # HM43374 is the correct wiring if your 2003 Lexus GX 470 came with the factory 7-Way and should be used as a replacement. If your vehicle didn't come with the factory 7-Way then the only way that I know how to help you is to offer theModulite Vehicle Wiring Harness Kit # C59236 which comes with just the 4-Way but does require splicing for the installation. If your GX 470 did come with the factory 7-Way the only other thing I would know...

• 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.

• 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 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...

• 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...

• 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...

• Troubleshooting 4-Pole Wiring Harness Installation in 2011 Lexus RX 350
• Curt 4-pole wiring harness # 56083, which fits your factory-tow-package-equipped 2011 Lexus RX 350, uses a square OEM connector to join the car's wiring. If your fuse is good then there may be a corrosion problem within the connectors. Disconnect the harness and check all contacts for signs of discoloration (even slight green or white discoloration can indicate corrosion that could cause a problem). Clean contacts as needed with a spray-on electrical contact cleaner. Since your fuse is...

• 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...

• No Power Using the Curt Vehicle Wiring Harness Part # 56083 on a 2010 Lexus RX 350
• The Curt T-Connector Vehicle Wiring Harness part # 56083 that you installed on your 2010 Lexus RX 350 will only work on models with the factory tow package. If you do not have the factory tow package then the correct harness for you would be the Curt T-Connector Vehicle Wiring Harness part # C55563. This option will attach directly to the battery for power as you can see in the attached install video. If you have called the dealer with your VIN and confirmed that you do indeed have the...

• Troubleshooting Installation of Curt T-Connector Vehicle Wiring Harness # 56083 on 2012 Lexus RX 350
• It sounds to me like your 2012 Lexus RX 350 may not be equipped with an active tow package. The plug may be there but the necessary connections may be missing. I recommend checking with your local Lexus dealer to determine what is needed to activate the towing package. Another option would be to go with the T-One Vehicle Wiring Harness, # 118478. The T-One connector plugs directly into the existing wiring at the back of your taillights. Just make your ground connection, route the power...

• Trailer Wiring Harness 56083 Not Working After Installation on a 2011 Lexus RX 350
• Did the dealer say it didn't need to be reprogrammed or that your 2011 Lexus RX 350 doesn't have the factory tow package? Because if it does not have the factory tow package then you would need to install a different wiring harness, # 118478. I have linked a video showing how it installs. If it does have the factory tow package then re-check the following fuses: Under the hood locations 43 and 44; Driver's side instrument panel fuse box location 22. If those are all good to go then you...

• Troubleshooting Lights Not Working After Curt T-Connector Vehicle Wiring Harness Installation
• The Curt T-Connector Vehicle Wiring Harness # 56083 is intended as a factory replacement harness for the 2017 Lexus RX 350 with the tow package. It sounds like you may not have the tow package, although you would still have the gray plug at the back. If you did not have a black converter box already plugged into this then you will need the T-One Vehicle Wiring Harness # 118255. In order to verify this you could use a circuit tester like the # PTW2993 to ensure that power is getting to...

• Troubleshooting Wrong 4-Way Flat Pin Size After Accident with 2012 Lexus RX 450h
• I've never heard of different-sized 4-Way flat connectors so I'm guessing the original 4-Way installed on your 2012 Lexus RX 450h is still there and was damaged when you were rear-ended. If you swap it out with the T-One # 118252 this will fix your problem. You can try adjusting the pins on your vehicle-side 4-Way but I would be concerned about damaging something on the wiring or your vehicle so swapping everything out is a better solution. Attached is an installation video of this wiring...

• Troubleshooting No Power at Factory Port on 2017 Lexus RX 350 without Factory Tow Package
• If your 2017 Lexus RX 350 didn't come with the factory tow package then an additional harness with a powered converter is needed to actually activate the plug that you used to install the Tekonsha T-One Vehicle Wiring Harness # 118252. This Tekonsha harness is designed for vehicles that came equipped with the factory tow package. Unfortunately, the converter harness is not available as a separate item from the manufacturer so your only option is to get the Tekonsha T-One Harness # 118255...

• Troubleshooting No Trailer Lights With New Wiring on 2015 Lexus RX 350
• Not necessarily. If your 2015 Lexus RX 350 came with the tow package then you just need the T-One # 118252, but if it doesn't have the tow package then you need the T-One # 118255 with the converter. The tow battery fuse slot would only be used if you were installing a 7-Way. Since the connector for the lights just have 4 pins for the trailer lights and ground I don't think it will really matter if you have a fuse in the tow battery slot or not. Before purchasing a wiring kit with the...

• Troubleshooting Trailer Left Turn Signal Not Functioning on a Trailer Towed by a 2001 Lexus RX300
• My first instinct would be to check the vehicle side trailer connector. Any dirt and/or corrosion can cause the harness to function improperly. Give it a good cleaning with a wire brush to clean out and off any corrosion. If you are still experiencing a problem after cleaning the pins, you will want to check them for the proper functions using a circuit tester like part # PTW2993. If the functions are all correct and working properly then there could be a problem with the trailer wiring,...

• 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...

• 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...

• 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...

• Should P3 Brake Controller Show No Trailer Connected when Stepping on Brake Pedal with No Trailer
• The P3 brake controller # 90195 only uses the 4 wires. The 5th wire you are referring to sounds like the illumination circuit that is not needed by the brake controller. I am not sure though what the year, make, and model of your vehicle is. You should get the no trailer connected message with no trailer connected when you apply the manual override but not with the brake pedal. Brake controllers like the P3 need to be moving (the vehicle moving with the brake controller in it I mean) so...
