If your vehicle came with a tow package it may already have all the wiring in place for the controller making it pretty easy to install - plug and play. Even if it has a tow package it may be missing the blue brake wire that runs from the controller to the trailer connection so the brake wire may still need to be added - not sure why some manufactures include it and some dont. If its already there you should be able to see a blue brake wire going into the tows hitch plug harness at the back of the car. If your missing the brake wire and your not comfortable running the wire yourself a place like U-haul
can do it for you pretty fast.
BTW keep us posted as to how the Acura MDX tows.... its high on my list of a possible replacement vehicles sometime in the future. They are a very popular vehicle in my area and have a smaller Acura for years so I know they are reliable.
