You are purchasing just the joystick itself, which can replace your defective or non-responsive current stick.  These are easily installed in the HORI HRAP V series, Qanba Q4-RAF's and some of the Mad Catz sticks, which use the quick disconnect wiring harness.

This is the complete set (minus the balltop) for those who plan on building their own stick.  The mounting plate is preassembled at the factory by Sanwa Denshi. 

• JLF Joystick
• Mounting Plate w/screws
• 5-pin Wiring Harness
• Dual dustwasher and shaft cover (solid black)
