OPT7 triple LED tailgate light install

[Rich Kesteloot]

I ordered this light bar for my 2019 GMC Sierra 1500 after I was rear ended 30 days after purchase.  it works great except the dealer plugged it into to my trailer port which disables my Rear cross traffic sensor and my parking sensor, not to mention it thinks I have a trailer attached every time I start the truck.  I order the adapter with the original purchase and send it to my dealer to have them install while fixing my frame etc.  I see they plugged the adapter in (see Photo) but it looks like they just extended the plug to the trailer input.  What is the adapter supposed to do?????? They don't seem to get it. Any insight would be helpful.  Thanks.
