I guess you have to describe to me what you call a crawl space then. If it is under a house, I call it a basement even if I have to crawl on hand and knee.
I would still say you need a running board, or bored holes.
Steve, a running board is a board run perpendicular to the joists and wires(smaller that 2#6 or 3 #8) are stapled to it.
