No black hall sensor wire

Hey guys.

Currently doing a Chinese controller conversion on my carrera vulcan e. I've been running it with just the phase wires and today decided to wire up the hall sensor wires so I can have speed. During my first attempt I accidentally ripped off the black hall wire so I decided to strip the whole wire back so I could try again but I found the black wire has disappeared and I now only have 5 wires.

Beneath the plastic sheath of the main controller cable there is bare wire that twists around all the other 5 hall wires and 3 phase. Is this what the black wire was connected to and is it OK if I don't reconnect this to the controller.

I've attached a pic of what ik looking at. The bare wire splayed out to the right is the one that was wrapped around everything.

The answer in no the strands are not the Gnd wire, the gnd wire will be Black sheathed all the way as the others are sheathed.
A simple get around is to cut back the larger outer sheath a bit more until you find the Gnd wire and solder an extension to it, solder a separate Gnd to the PCB and run it out side of the main cable.
Alternately buy new 9 wire motor cable and solder it to the wires inside the controller, cut the controller wires leaving enough of a tail to do.

The black wire that was pulled off was connected to a soldered blob that was on the wire sheath hence why i thought that was the case.
