This kit helps wire the autopilot servos. It includes 20 feet of Tefzel wires: two pairs of twisted 22 gauge network wires, one 22 gauge quick disconnect wire, and two 20 gauge wires for power and ground. Also included are three D9 connectors (one male, two females), 18 pins, a pin insertion tool, shrink tubing, and tie wraps. One kit is required for each servo. A crimping tool is required (not sold by Dynon) to attach the pins to the wires.
