Trailer Wiring Harness and Other Parts to Tow a Trailer with a 2017 Lexus RX 450h

Question:

I have installed the hitch and now I want to install the wiring harness for this vehicle, do you have the harness and any pictures\videos? Do I need to run a wire to the battery?

I recommend the # 156083 trailer wiring harness on your 2017 Lexus RX 450h. I've linked a video of the harness being installed on a 350 for you to check out. This is a custom harness that connects behind the rear bumper.

To tow a trailer you'll also need a ball mount and hitch ball. I've attached a link of our selection of ball mounts for a 2 inch hitch receiver as well as an article to help you determine the correct rise or drop you may need. Once you choose a ball mount you can then choose a hitch ball to fit it.

One way to make choosing a ball mount easier is to go with an adjustable ball mount like the B&W Tow & Stow # BWTS10038B. It features the ability to be flipped under the hitch when not using it and will provide up to 5-1/2 inches of rise or 5 inches of drop.

For a pin and clip to fit you can use # PC3 or if you'd like to have a locking pin you can use # BX8858.

I've also included links to some articles on towing that you might find helpful.
