I will look behind the trim panel. Only the all wheel drive is available with TO this year and mine is a front wheel drive. I have the correct convertor box, just don't know where to put it! Was going to pay the dealer until they told me they weren't sure where it goes either so thought I would try it myself instead of paying the $90hr shop fee. Thanks for the info.
Try another dealer for the install if you can. Without the tow option package the install is a nightmare according to others on this site. Don't know personally.
The other issue is the greatly reduced tow capacity for non-TO vehicles. From what you list as being towed it shouldn't be a problem but don't be tempted to push it.
The 2010's are different than previous generations as far as towing, there is a receptacle under the car for a trailer light pigtail so it just plugs right in. The towing capacities are just less than a Camry/ES350. The dealer knows that the light controller is in a different location than previous, he just has not been able to discover where it goes. You can still buy a tow kit from lexus that includes the hitch, pigtail and controller although they suggest install on awd for some reason. I will figure this out this weekend and post my results.
