As you refer indirectly above, be careful to keep the wire away from moving parts inside the pedestal...chains, cables, etc.
That said, I considered the same but found it more attractive to run up inside a guard tube then enter the instrument box without ever exposing the cable - a cleaner look and I think safer from abraision and weather. I 'hogged out' the SS tube right where the navpod box attaches and passed the AP cable into the navpod at that point. No unsightly wires.
