The system harness has 2 red/white/black heavy gauge servo wires that power the bus and servos..
Options..
1. Add a servo wire with the signal wire pulled to the Bind port from any power source.(after it its set up and functioning) for more power
2. Add a Y cord downstream to any of the servo wires from any Power source, and it will add to power available for all the 5 ports..
3. If you are using a matchbox downstream (twin rudders), add a power source into one of the numbered ports and it will also back power and add to power available..
