===== Capcom CPS2 Kick Connector Pinout =====

The Capcom kick connector is primarily known for adding buttons 4-6 (the kick buttons) to its fighting games, but it also adds external volume controls and additional player controls, like 3 or 4 player inputs, paddle controls, etc.

===Technical===
The connector has 34 pins in 2 rows, housing and pins both made by Hirose.  The harness uses a socket connector, the PCB side uses a plug connector (Remember, the pins determine plug/socket, not the connector housing).

Most people will only be interested in the player 1 & 2 kick buttons, meaning only 8 wires (3 buttons, 1 ground per player) are needed.
