Oh... I see now, you using a hole to get into 1" tubing of the guard... yes, I can see where large hole there would be a problem.
I actually ran my wires down inside the pedestal itself, and wire tied them back out of the way of the chain and cables. In my case I had a wood spacer between the pedestal and the compass and I carved a grove into the bottom of the wood to provide a way out. Since my GPS is not enclosed in a pod, having the wires run outside from the pedestal to the RAM mount was unavoidable, but it also allows swiveling the GPS display when I'm navigating in the rain from under the dodger.
Sounds like in your case splicing may be unavoidable.
