I have looked high and low for a way to get the 4 gauge wire from the battery into the cab. I really would prefer not to drill a hole. Is there a existing grommet that will work? Thanks.

I have a 4 gauge wire run through a grommet under the dash behind where the steering wheel is up towards the top, there is a bunch of stuff already going through that grommet but another wire can be passed through with a bit of coaxing.
