JFR. Hi In my 32 there was a moulding to in the ceiling behind the forward bulkhead. You could access this from a small removable panel where the mast cables came in. I used a long plastic dowel to feed a draw wire into the moulding and out in the back of the cupboards behind the cover plates in the back of the cupboards. Then I feed the cables back to the control panel behind the cupboards. I also pulled a draw wire in as a spare for future use. Basically it’s the same route as the VHF cable takes. You can also take any wires across the boat at the same point. As we added more electronics to the 32 we filled that route and then ended up putting a flexy conduit across the ceiling by fishing it through the lamp holes. It was tight but gave us another route.
Hope this helps.
