My 69 cat has a rear defroster in it, but I don't see it in the shop manuals as being in cougars. I was wanting to know the proper location for the control switch if indeed they did come with this option. The knob on the switch looks like it would match the knobs of wipers, etc and says defroster on the bracket. I didn't see any holes under the dash that looked factory for the bracket hole spacing. I can take pics if that would help. Any ideas??
