Hmmm….the hole I have was factory drilled and large enough to fit the yellow connector even with several other cables already in it.. As long as your clam shell covers it I dont why you couldnt.A abrasive burr like this would work too if youre careful. This might be easier to enlarge a hole with this instead of using a large drill bit.Last edited by GRR884 on September 11th, 2013, 11:45 pm, edited 1 time in total.
