The Nissan Path

I am adding a 7-pin trailer connector to replace my 4-pin connector (2012). The kit (not from Nissan) did not include the trailer connector adapter that fits the factory hitch (see picture - this is not the kit I ordered). Anybody know where I can find the PN, or where I can find the part on-line. Thanks

I went to the dealership yesterday and the bracket only comes with the hitch. Even the parts manager recognized the stupidity of that arrangement.
