Question:

What product do you have for the 2013 Lexus RX 350 without the tow pakage? I have a Curt trailer hitch used for my bike rack, but would like to now tow a small utility trailer. Thanks for your help.

If your 2013 Lexus RX 350 did not come with the factory tow package I recommend using the ZCI harness # 119250KIT. With this harness you will not have to splice into the vehicle wiring. It has connectors that clamp around the tail light wiring and sense the current flowing through the wiring. It's kind of awesome!

Since you want to do some towing I recommend 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 have the right rise or drop to tow the trailer level, use the link I have included that explains how to measure to choose a ball mount to tow the trailer level.
