28P JAMMA Wire Harness for Arcade Game Boards

Build, repair or upgrade a compatible arcade machine with this complete 28P JAMMA wire harness. Designed to connect arcade game boards with joysticks, buttons, coin mechanisms and video interfaces, it provides an organised wiring solution for arcade cabinets, retro gaming systems and custom arcade projects.

The harness is available in several wire and terminal configurations, allowing you to select the version that best matches your arcade buttons, joystick and game board connections.

Complete 28P JAMMA Connector Harness

The 28P connector provides the main interface between a compatible JAMMA game board and the arcade cabinet wiring. It supports the essential connections required for player controls, coin operation, audio, video and power when installed with compatible arcade hardware.

Multiple Wiring Configurations Available

This JAMMA wire harness is available in multiple configurations to suit different arcade cabinet components and terminal sizes.

2.8 mm and 4.8 mm mixed terminal wiring
2.8 mm button wiring with 5-pin joystick connection
4.8 mm button wiring with 5-pin joystick connection
All 4.8 mm terminal wiring

Please select the correct wiring option according to the terminal size used by your arcade buttons and the connection required by your joystick.

Compatible with Selected Neo Geo and Pandora Boards

The harness is suitable for selected JAMMA-compatible Neo Geo cabinets, Pandora arcade boards and other compatible arcade game systems. It can be used in classic arcade restorations, modern Pandora installations and custom-built arcade cabinets.

Joystick and Arcade Button Connections

The wiring harness provides connections for compatible arcade joysticks and control-panel buttons. Selected variants include a 5-pin joystick interface for compatible SANWA-style joysticks, while other versions use individual directional connections.

Coin and Video Interface Wiring

The harness supports compatible coin mechanism, coin switch and video interface connections used in traditional arcade cabinets. This makes it suitable for coin-operated arcade machines, home arcade systems and commercial-style cabinet projects.

Suitable for Arcade Repairs and Restorations

Old, damaged or incorrectly modified wiring can cause arcade controls, video signals or coin mechanisms to operate incorrectly. Replacing the existing harness with a compatible JAMMA wiring set can help restore organised and reliable connections throughout the machine.

Compatibility Notice

Incorrect wiring may damage the arcade board or connected components. Always confirm the required pinout before applying power.
