Hi Tiernan, welcome to the forum. The wiring diagram is pretty clear I think. Best get a piece of cardboard and poke the pot shafts through and write on each pot if it is bridge or neck and if it is tone or volume.
Let us know which part is confusing for you. Here is the link : http://www.pitbullguitars.com/wp-con...s/pdf/IB-5.pdf

the hardest part when I wired mine was working out the correct hot and earth lugs for the stereo jack.

Also a tip usually the control cover isn't recessed you may want to do that before sanding and check the jack retaining nut will reach the thread, best do this before you start sanding the body
