Since this sounds like you first DIY project I'll actually give you some
drywall advice instead, instead of trying to fish the electrical wire
everwhere just cut a 1 foot wide strip the length of the kitchen out of the
drywall. TRUST ME it's just as easy or easier to patch one big hole as itis
to fix several smaller holes. If you cut the hole right down the centre it
should leave room to run each wire down the sides.
