Wiring or pink wiring, as referred by other people, is a material that can either be gifted or requested by neighbors to assemble appliances for recreational purposes or for the in-game goals/quests. They can not be acquired with coins or gems. A successful chef has a lot of friends, that can help him out when he needs materials!
