Rotax DD2 SHIFT IGNITION CUT-OFF

Hi everyone, i bought a secondhand DD2 kart and the wire for the ignition cut-off for shifting is missing. Was wondering if anyone could tell me which wire it is? Mine is the ‘older’ version as I understand with only 4 wires going to the coil. I did find a brown wire going into the same harness, but earthed it out with the engine running nothing happens. Also not sure if this could be the correct wire and the cut out only happens at higher rpm’s? Any help appreciated.

  • edit: the brown wire I found is simply the brown wire that plugs into the coil along with the 3 others. Is this the wire that can be grounded to change at which rpm the exhaust valve opens or something like that…?
