How to Tell if 2007 Lexus RX 350 Has Factory Tow Package

Question

Question:

My 2007 RX350 has the 30AMP fuse marked towing in the fuse box. How can I determine if I just need the wiring harness from the connection in the rear panel drivers side or if I need the entire kit with convertor etc. Thanks for the help.

The 30 amp fuse marked for towing that is located in the fuse box of your 2007 Lexus RX 350 does not necessarily indicate if the vehicle has the factory tow package installed. The actual features of a tow package vary greatly between different auto manufacturers, vehicle model years and models.

Looking at the online owner's manual for your vehicle, it appears that the factory tow package included a trailer hitch receiver. If the vehicle did not have a factory hitch, and an aftermarket trailer hitch needed to be installed, then you most likely do not have a tow package. If this is the case, I recommend using the Tekonsha T-One Vehicle Wiring Harness # 118478 to install a 4-way trailer connector. The T-One connector will plug directly into existing wiring behind the trim panels in the cargo area on your vehicle. I have attached the installation details for you to check out.

If your vehicle does have the factory tow package, there should already be a 4-way connector at the rear of your vehicle along with the factory installed hitch. If you are unsure of what you have, I recommend checking with your local Lexus dealer. Using the vehicle's VIN, they should be able to tell you exactly what was installed at the factory on your vehicle.

Did you install the Tekonsha T-One Harness # 118478 mentioned above? If so, there aren't any other components that need to be added for it to power the trailer's lights when connected. This harness simply tees into the tail light circuits. Did you make sure to run the hot lead up to the vehicle's battery?

Thank you for the photo; unfortunately there really is no "fix" for the Curt Trailer Hitch #13530 touching the spare tire on your 2008 Lexus RX 350. While I can understand wanting to lower the spare a bit during the install, that…

For your 2007 Lexus RX 350 I definitely recommend going with the Tekonsha T-One Wiring Harness #118478. The Tekonsha harness, like you mentioned, provides a more secure ground connection to the vehicle. Tekonsha is also more well known for making…

The white wires on either side of the converter box are ground wires. The ground is already in the connector that runs to the driver side taillight harness so you would not need to ground the box beyond that.

I would recommend the Draw-Tite Trailer Hitch #75153 over the Curt #13530 for your 2009 Lexus RX 350. Curt has been revising their instructions on many hitches to include that per their warranty with any non-trailer load, like bike rack or cargo…

If you have the factory tow package then you can access that port behind the drivers side in the hatch of your 2009 Lexus RX 350 to install 4-way harness #18002. Harnesses #C55563 and #118478 can still be used, and will provide higher current with…

The RX350 with the tow package is somewhat of a rarity. Since your Lexus has the wiring port in the rear driver's side cargo area, I would recommend using a circuit tester like part #PTW2993 and check to see if that port is active. Activate the…
