Claas sprint 4000/5000

[Ndj7919]

Hi, does anyone here own a sprint chopper wagon?. The reason I ask, previous owner has been in the electrics after they're bed aft button failed and simply cut wires and wires up the aft direction to the forward button (rather than do the right thing and replace the button). Has anyone got the similar controller they could take a photo of the wiring.. this would help me massively..

Also some help with which button does what, yellow (top left) indicates spool pressure, don't know what the red/green lights do on the buttons, my guess is missing red button is bed in, green button bed out, the lights inside buttons are illuminated when either of the pressure pads are operated. I have no idea what the bed switch does, another guess, when switched away from middle neutral position, the bed moves when the grass above the intake operates a pressure paddle/pad.. I have a manual but it doesn't seem the manual is the original that came with the wagon.. please help
