Has anyone put on a Corbin seat? I looked at Corbin's web site and their instructions doesn't match my 2005 650. The light wiring on mine is tucked behind a plastic panel in one part and I see no way to get the wiring out from behind the panel without disconnecting from somewhere. Also I see no way on taking the actual light out because it looks like it was fastened or screwed from the top down. Also the bracket on the rear of the seat that latches, the head of the bolts are hidden too. Does the large panel under the backside of the seat come out to access all of these bolts?
