my wife got a 03 extreme a couple months ago. so now i'm trying to put a kenwood x469 in it. first problem was the damn harness was different then my 2000 s-10, i got the right harness now, but my second problem and my question is the adapter install kit don't fit in the dash. do i need a different adapter or do i just file some of the dash material away to make it fit? anyone else have this problem or any advice would be greatly appreciated. by the way to clarify myself it don't fit because the hole in the dash is too small for it to fit into. and it's not like the adapter is way to big, it's tight around the head unit.
