One of the things Van’s has said about this kit is that they want to make it as complete as possible including wiring. The wing kit comes with wire looms for the lights, ADAHR and autopilot servo pre made.  All you have to do is run the wires.

One end of the wire loom has the molex connector installed. The other end of the wires are attached to pins but you run them and then insert the pins into empty connectors.
