Quick question... I worked out a deal when I bought my 2014 MDX AWD, for the 4500lbs trailer hitch to be installed at no cost. After recently inspecting it...there doesn't appear to be a wiring harness. Does this mean they installed the smaller hitch? Or does the wiring harness also go on the smaller hitch and they just screwed up the installation altogether?

 

wire harness is extra

 

You might also need to add the Trailer Hitch ATF Cooler for +$275 if you have sh-awd model and you need tow up-to 5000lbs. No sh-awd, no ATF cooler needed.
