Cable Ducts?

[oldfielder]

Hopefully someone can set me straight before I cut a hole where I shouldn't. Are there rigging ducts running aft on the 23 cc from the console on both sides of the console? There are two raised boxes under the console and one of them has been cut open and all of the wiring running aft has been routed through this duct, which is on the starboard side. The one on the port side has never been cut, so I am wondering if it in fact leads to a duct. If so, I'd like to use it to run the wiring for my tabs if I add them this year.
