RV-6, not sure how similar to RV-14 but here's a pic. Comes out the bottom of the stick, zip-tied over to the left on bottom side of the control tube with enough slack for full motion.
My approach is similar to some others presented here. First on the stick you need to get the wiring down near the pivot point. That way the stick end of the wiring is not moving a lot. I then made a service loop to allow movement of the stick and clamped it to the outboard rib. I moved the stick around to determine exactly where I wanted the clamp and how much of a service loop I needed. Then I routed the wire near the corner of the rib and the spar. This keeps the wiring out of the way of the stick movement. I have a connector down near the bottom skin so I can remove the entire stick if needed.
