Hitch & wiring on 2015 PIP?

Has anyone installed a hitch and trailer wiring on a 2015 PIP?

I found ZERO posts about installing a Curt 11276 hitch on a 2015 PIP. Or installing ANY OTHER hitch on a 2015 PIP.

Same applies to adding wiring for towing a trailer behind a 2015 PIP.

Is the 2015 different than the 2014 in the area where the hitch would go? And where the taillight converter would be spliced in?

 

I have not found posts which say the 14 and 15 differ, but I haven't found any authoritative source saying they are the same. Well, depends on how someone defines "authoritative", I guess. In this article, Autotrader.com says, "After a 2012 debut, the Prius Plug-in is unchanged for the 2015 model year." What bothers me as I am waiting to take delivery of a 2015 PIP in 2 days, is that I cannot find any hitchmaker (including Curt and Draw-tite) whose specialists or whose website says that their hitch that "works" for a 2014 PIP also works for a 2015 PIP. Ditto for a wiring harness. Since the '15 has been out for quite a while, I think it's reasonable to expect that by now hitchmakers would have updated their files to state that the hitch/wiring kit works for 2015 PIPs. Yet, they have not. In fact, two reputable hitch installer businesses who I contacted called the Curt and Draw-tite manufacturers and spoke to their technical people. They all said that their hitches and wiring kits were NOT approved for installation in a 2015 PIP. And, so it goes. Fun being on the "bleeding edge", I guess.
