Well... I just figured, as long as they had it on the lift and were in there, they might want to make some easy money. I haven't talked to them yet, so who knows. The dealer I used to use near me (when it was under warranty) is long gone and now there is a new dealer (part of a large group of dealers) in another location relatively convenient to me, so we'll see what they say.
Back in the day, I had to repair trailer wiring on brand new trailers the motorcycle shop I worked in used to sell (yes, they were cheap and the wiring never worked as delivered), so it isn't like the job would be completely alien to me. I just didn't want to futz with it if I didn't have to.
Is there some kind of plug on the '02 Liberty behind a panel or something that the trailer harness connects to?
