Use a magnet to locate the steel beams in the area you are interested in drilling-- you will want to avoid drilling them.
Unless you are accessing an area opening into a wheel well, I would simply drill a hole sized for a short length of hose or PVC through which you will feed the wires. Use polysulifde, etc to seal bulkhead to hose or PVC pipe. Seal with polysulfide after running wires.
