I have the Krome Works hitch and the wiring harness from the forum. +1 on the wiring harness, -1 on the hitch. The harness is very easy to install, and helps avoid the need to cut into the bike's wiring. The Krome Works hitch, while very easy to install, has a terrible positioning for the attach points for the safety chains. Carbon One's hitch has a better placement for these attach points.
