Since I was using TBOLT 4-servo harness (
http://www.dreamworksrc.com/catalog/...-12-Extensions ) the first thing I had to do was create new openings in the fuselage since the stock location would not work with the connector and wing opening.
FYI: The metal pins do not line up perfectly and take some "fitting". Do one at a time and take your time, and all will be fine.
