Wires
I did not restrain the wires. I, like most, protected the wire from any possible abrasion by sliding them in a piece of tubing. My lower fairing is attached with rivets.
For long term, remember that the rudder will come off eventually, so I made a wiring connection in the empenage area, or at least leave a service loop so it can be cut and spliced back together.
The thing that concerned me with the wire routing between the tail and rudder the most is, where it is exposed to the elements and movement with every rudder deflection. The fewer bends in the wire, the less movement. I drilled a hole between the 3 lower VS spar attach bolts large enough for the wire and protection to pass through. Then copied that location accross to the front of the lower rudder fairing and cut a "slot" about 1.25 inches wide and a little taller then the wire bundle. This way, the wire is routed basicly flat, through the gap and the slot allows for the rudder to move without twisting the wire. There is supposed to be a hole drilled in the lower fairing to allow for water to drain.
Email for pictures. YMMV.
