My 1.6 Does not have the Hole - After removing the glovebox (what a job that is) I found there was Something (dont know what) fitted there ... Back to the drawing board.
on AC models there is not little flap, mine aint air con so i was ok, but that little flap tuns out to be a big pover that pops off and lets noise in so best it to drill as small of a hole as you need in it then upt wires through then put sealer over it and put it back in, no engine noise then
