I need to add a momentary rocker switch for an exhaust cut-out. I am considering locating the switch on the dash, as my car has what appears to be a couple of blank spots next to the Traction Control switch. Has anyone taken apart this part of the dash? I am looking for some insight into: A. Can these blanks be used? B. How to access that panel? Does this pop out, or am I going to need to pull most of the dash out to access the blank slots from the rear? Thanks in advance!
