Feedback on my decision and results:
Finding a wiring kit wasn't that easy. I finally got a DRAW TITE product from 6 Robbles in South Seattle (Boeing Field area) for about $50. The installation required tailight assembly removal and modification, but it went smoothly and the instructions were almost perfect. The whole thing took about 1 hr 45 mins, at a liesurely pace.
It tested out great. I'm happy with the installation and am looking forward to flailing away on the oars.
