Abs sensor wiring

[Craig by the way]

By the way does anyone know if the wiring harness going to the ABS sensors is one big loom or is it in several sections. I ask because I need to change the inboard cv boot and I've just noticed that the abs sensor on the same side has a broken wire and I don't think there is anything left sticking out to solder the wire on to.Can I just replace the damaged section our will it entail changing the whole thing??????.
