Hi, Have a 2005 Elnagh Marlin 66 and want to change the shower vent for a fanned type, vent right diameter with fan located - anyone ever taken one of these apart as I am looking for a way to not surface mount the wiring but run it through the ceiling above the roof board to the feed to the bathroom light next door - so before I start taking stuff apart and poking around I thought I would inquire of the hive mind?
