Trailer Wiring Recommendation for 2015 Lexus RX 350

Question:

I just installed the custom Curt trailer hitch on my 2015 Lexus RX350 and it has the wire connector for the 56083 custom wiring harness right where etrailer said it would be. Is that all I need to verify that the 56083 wiring harness will work with the Lexus towing kit, or us there something else I need? I bought the car used so not sure what constitutes an installed towing kit, or if it is already installed beyond the harness., but I doubt it. I plan to use the hitch for a bike rack or maybe a uhaul trailer, light duty, so I dont know if a installed towing kit means just the wiring harness or the transmission cooler, etc. that I think is required to haul a boat or do other long distance heavy towing.

Based on our experiences and what you listed as having in your 2015 Lexus RX 350 all you'd need for trailer wiring is the 4-way kit part # 56083 that you referenced and you'd be set. I attached an install video for thits for you to check out too but I believe you may have viewed it already.

Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.

If the ball mount kit does not include a ball mount with the right rise or drop to tow the trailer level, check out the link I have included that explains how to measure to choose a ball mount to tow the trailer level.
