Thanks for the photos, Russ!

The square 4-Pin plug you have on your motorcycle isn't common so you'll need to cut it off and rewire it to the Pollak 6-Pole # PK11609 so they match - you'll just have to match up the pins per function.

You might also need to install the Curt Powered Tail Light Converter # C59236 if your motorcycle has the brake light circuit separated out on it's own. In this case you'll install the Curt wiring and then cut off that 4-Way and install it to the Pollak 6-Pin.
