Hi All, appreciete some help. A photo of a completed JB-4 Bass setup? because I feel like I've been hit by the dumb stick with the wiring digram at https://www.pitbullguitars.com/wp-co...B-4_2014v2.pdf

1. Reference to purple wires? the diagram doesn't have any and none of the actual wires are purple
2. The diagram shows "Shield (metal wire sheath)" going from the base of the pot to half way along the blue and red wires? Surely not?

The black wires that come out of the pickups aren't included at all.
