58/15 LT from 2017 HBii wood library coil tap?

[Diaz0105]

My volume pot took a dump so I decided I’d take this opportunity to upgrade and ad coil tap. I pulled out the pickups and determined there is only 1 wire. Does this mean they can not be taped or split? Can I send these in somewhereand have a wire added or ??? Any help would be sweet
Thanks Anthony
