• Does Curt Trailer Wiring Harness Really Fit 2026 Toyota Grand Highlander without Tow Package
  Hey Fred, you would need the Toyota harness part # PT725-48241 but this is not a complete trailer wiring harness. This is basically an intermediate harness that the Curt # C55245 needs if the Grand Highlander does not have the OEM tow package. I would say it's a little confusing to say this fits all Grand Highlanders but that is why we state it only fits the versions that have the tow package. I think the most ideal solution would be for Curt to include the Toyota harness but it's most...

• Availability of Trailer Hitch for 2025 Toyota Grand Highlander XLE Hybrid
  Hey Jeffer! Yes, we do have a hitch and wiring for your 2025 Toyota Grand Highlander XLE Hybrid. For a hitch I recommend the Curt Trailer Hitch Receiver # C26VV. This is a Class III hitch with a bolt-on installation and comes with a limited lifetime warranty. For wiring, if you have the factory tow package port you can use the Curt # C55245. If you do not have this factory connection the only option is the universal Curt # C59236. I attached an installation video below for the hitch,...

  Hey Derek, congratulations on the new Grand Highlander! For a hitch I recommend the Curt Trailer Hitch Receiver # C26VV. This is a Class III hitch with a 2" receiver and a bolt-on installation. Since you don't have a factory hitch it is safe to assume you do not have the tow package either. For wiring, you will need the Curt # C59236. This is a universal splice-in wiring harness. If you would rather have plug and play, you can use the Curt # C55245 along with the Toyota converter PT725-48241....

• Does a 2022 Toyota Highlander Need to be Flashed After Curt Aftermarket Wiring Installation?
  Hey Mike, thanks for reaching out! You won't need to have the 2022 Highlander flashed after installing the Curt T-Connector # C55245. This installs on a vehicle that already has the factory tow package so it should activate after installing the fuse. If you're having issues with the plug working after the installation, then I recommend removing the Curt plug and using a circuit tester to test the pins on the OEM plug to see if the functions are getting that far. Let me know what you find!

• Difference Between Tekonsha and Curt Trailer Wiring Harness 2020 Highlander
  Hey Todd, I can assure you that the Tekonsha part # TK74FR and the Curt # C55245 that both are a confirmed fit for your 2020 Toyota Highlander are wired the same and would work identically. If it were me I would go with the Tekonsa just because it's currently priced better but also in general we have the best luck with the Tekonsha harnesses.

• Comparing Curt and etrailer Hitch for 2026 Toyota Grand Highlander
  Hey Jack! That is a great question that comes up pretty often. The Curt # C26VV and our own # e69ZV actually share the same design. The specs are all going to be the same so the main difference is in the finish. The Curt hitch has a glossy finish and the etrailer hitch has the matte black finish. I prefer the matte black since it does a better job hiding dirt and also tends to blend in better with OEM trim on vehicles. If the finish doesn't matter to you I would go with whichever one...

  if your 2003 Toyota Highlander has a tow package plug located in the driver's side rear cargo area under the floor (see instructions for installing Item # 118413 on where to look) then your Highlander has the tow package. If you find a plug, use a circuit tester like Item # PTW2993 to check to see if it is active. If you do not find a plug or the one you find is not active, then you do not have a tow package. Another way to find out is to contact your local Toyota dealer, give them...

• Need Hitch And Wiring For A 2020 Toyota Highlander Limited AWD
  Hello Geoffrey. For your 2020 Toyota Highlander Limited AWD I recommend the etrailer Class 3 Hitch # e75ZR. This hitch will be compatible with your T165/90D18 temporary tire. Anything larger than an 18" wheel would not fit, but you will be able to continue to store your spare under the vehicle with this hitch installed. As far as the kick sensor, the hitch may interfere with it slightly. In almost every case, the sensor will still function, it will just work a bit differently. Instead...

• Does Wiring Harness for 2001 Lexus RX 300 for Factory Tow Package Require Programming
