Recommendations For Trailer Hitch Receiver And Wiring On 2017 Lexus RX 350


I recently purchased a 2017 Lexus RX 350 with the towing package. Dealer was quoting me a price on installing a hitch in excess of $1000, he said due to the amount of labor involved. He said the entire rear bumper needed to be removed for the installation. Looking at your video it seem very easy. I might even try this myself. The concern I have is about the wiring harness. The Curt T-Connector Vehicle Wiring Harness # 56083 recommended wiring harness indicates that it plugs directly into the OEM tow package port. Where is this port on the RX 350? And finally, how does the wiring harness attach to the underside of the vehicle? Does it just hang there or is there a way to have it look more professionally installed, like the the 4-pin plug belongs there and isnt an add-on?

For your 2017 Lexus RX-350, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75540 or the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13272 which are installed almost the same way. I give Draw-Tite hitch my recommendation based on the capacity edge for use without weight distribution system.

For your trailer wiring, I recommend the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # 56083. This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, along the driver's-side frame rail. The No-Drill Mount Bracket Short # 18140 along with the mounting bracket # 18144 are recommended for your wiring because it is on the exterior of the vehicle.
