Feb 17th, 2013 (9 Hours). I spent the day wiring the Fuel Pump and Tunnel Battery relay contractor. Process was simple but time consuming, working in the tunnel is tight and the routing of the wire is very critical along with securing the wires. I wired up to cables one for the relay that included a diode, this cable is routed up to the general area of where I think the Tunnel Battery switch will be located with some “extra” cable since I don’t have the exact location determined. The Fuel Pump wire route deals with similar issue as did the Tunnel Battery relay. I created a connector that is 5 inches long, connects to the terminals on the fuel pump on one end and then has a connector for easier removal and install if the need is required (I hope not). The cable is the routed up to the VPX Pro future location with some extra length added on. I wrapped the high pressure and low pressure AC lines in insulation to help keep them more efficient and keep them from having water vapor condensing on them thus getting it all on the inside of the aircrafts walls, etc.
