Does anyone have a 2010 RT trailer harness and controller? I picked up a used 2010 RT-622 and would like to use a factory harness. I already have other harness options (any one want to trade?) in hand but I'd like to pick up the harness with the round plug. I used to have a hitch and trailer but sold it and I liked the round plug setup. It would save me from cutting, splicing and soldering (I'm electrically challenged) and would fill the holes in my left storage bag from the last harness that was there.
