QanbaPS3 Xbox 360 PC Multi-Console Joystick PCB

Looking for help connecting cables to this Pcb. My buttons and joystick are happ so i will have to replace the connectors with larger ones. No paperwork came with it came from hong Kong. Trying to connect to a old Red Octane joystick with 8 buttons and start and select. Only thing I can figure out is the joystick commands with the ground wire.
