HELP WITH ABS WIRE

Hello, I've got a C1155 (Front left open circuit ABS wheel speed sensor) Coil light, ABS light on a 2.2D sport  I've replaced the sensor already to no avail but noticed yesterday while tinkering that the ABS harness connects to a plug (not the sensor end) behind the wheel arch and if you follow it closely it continues up the side of the car and leads to a connector just behind the right hand side of the wheel arch, I've found that the wire is actually severed there which to me looks definitely to be the problem. I need help finding this wire online so i can buy a new one I have looked for hours and the only thing listed is the harness which is not where my fault lies. For everyone that's replaced or knows what the harness looks like you'll know one end plugs into the ABS sensor and the other end plugs into another connector, my issue is there past that connector the wire is kaput so I need a new one of those. If anyone knows what this part number is I'd be ever grateful, thank you for reading and I hope somebody is able to help me.
