To save anyone this problem of having a bunch of wires thru the same hole, try this. Run one fat 6-8 gauge wirefrom the battery thru the hole and hook it up to a fuse block that you can buy at Pep Boys. That way you can run however many amps you want, depending on the size fuse block you bought, and have all the fuses in one place and it will all be neatly tucked away under the dash.
