Stepper Motor Control with Arcade Joystick

Ash, I connected my micro switch as indicated in the attached drawing. I know everyone says that a 10k pull down resistor should be in the connection as well, however, I'm not using a breadboard so therefore I physically need to know how to connect the resistor within my current connection setup.

From the switch pins I connect to the Arduino as follows:

Switch COM to 5V on Arduino
Switch NO to D4 on Arduino

I appreciate your help very much!

Thanks
