Step 3.

3.) Cut off the end of a Servo Extension and strip back the wires.

4.) Solder the Black wire of the Servo Extension to the strip connected to the Emitter of the transistor.

5.) Solder the White wire of the Servo Extension to the strip connected to the end of the resistor (not the transistor end).
