Hi and welcome JohnL.
These questions are best for a build diary or a post in general support.
It does sound like they have given the wrong wiring set. Definitely do not need 2 capacitors since there is only the 1 tone control.
A type pots are usually for volume and B type usually for tone.
I read the post from Fender3x at https://www.buildyourownguitar.com.a...l=1#post200643 and he mentioned that he uses the A type for both volume and tone!
I would try using the two A-type pots for the pickup volumes, a B-type for the Master volume and B-type for the tone.
If you are worried about this then drop Pitbull an email!
Hopefully others will add more.
