So, still a bit cold up here to get out, but needed to pull the boat out to summerize it. Trailer lights worked fine, pulled her out of the garage and I can't back up. This happened once at the beginning of the season a year or two ago. Dealer checked it out and said all was fine. I ran the boat/tailer up and down a rural highway thinking it was just sticking from sitting since October. No such luck. Won't back up.

The wiring harness connections look a bit beat up and I'm thinking that might be the problem. Anyone know where to get new harness (boatmate direct)? It looks like plug and play on the 08 trailers.

Could it be anything else?
