additional questions for installing a tiller pilot

I installed the tiller pilot with a bracket "home made" by my brother. Looks quit nice to my opinion. In the end the biggest problem was to get the wiring correct. Hanse could have invested in some spare tubing for wiring. I had the same problem with adding instruments on top of the entrance. I still do not know how to get from the instrument panel on top of the entrance to the navigation table inside. I can get into the ceiling but inside everything seems to be blocked by polyester and glue. In the end I used a spare cable from the mast lights.
