Well you can see the 4 H-bridge MOSFETs clearly on the main board, shouldn't be too hard to figure out
what's driving their gates if you trace the signals.

My guess is that 3/6 thick connections are to the brushed D.C. motor, apply +/- 12V to run the desk up or down.
You could use a Pololu motor driver for this.

Red=+5 V power to the Hall sensor, thin brown = sensor ground.
Yellow = count pulse output.
Green = limit switch.

You can find 12V, 16A XBox power supplies at thrift shops for about $10, or on line for a bit more.

Thanks a lot!
The problem is now solved!

Red=+5 V power to the Hall sensor, thin brown = sensor ground.
Yellow = count pulse output.
Green = limit switch.

I guess you are right about this!

I bridged the wires for the count puls and the limit switch. The controller now interpret the signal as coming from two motors.

I will post the result here when I'm ready with the build.

All the best!
