Installed the stick grip harness for both pilot and copilot sticks. Routed the wires through the left side corrugated tubing with a pull wire. Had to pull left and right wires separately since there is very little room left in the tubing for wires. Was able to route the wires through existing pass throughs in the wing spar and to the vicinity of the bottom of the sticks. Plan to use 15 pin connectors and have the wires exit the stick about half way down (hidden by the stick boot) and into the area below the sticks. Will drill an exit hole in the stick on left or right side since the side loads on the stick will be less than the forward and aft loads. Photo of wires in my hand are the remaining wires from the wing that will have to get to the panel somehow. (Heated pitot controller, nav, taxi and landing light wires)
