Have a 2010 RX350 without tow package. I installed the Curt hitch without any difficulty--No harder than changing a tire. My question is this, I ordered the towing converter box from the dealer, the rear floor was easy to remove, where is the box to be pluged in? The inputs don't look like they match any of the plugs. Any help would be appreciated. Thanks, Bob

I installed a Curt hitch. Very simple, no more complicated than changing a tire. I purchased he towing converter box from the dealer. My question is, where does the box plug in. On the 2010, removing the rear floor is quite simple. Just need the wiring diagram that shows where the box goes. Thanks, Bob
