It looks like that one has gone away. The wiring diagram is this one https://www.pitbullguitars.com/wp-co...s/pdf/JM-1.pdf

I built one here last year: https://www.buildyourownguitar.com.a...ad.php?t=11617

The generic guide here is suitable https://www.pitbullguitars.com/instruction-manual/

It's a pretty straight forward build, especially since the wiring is mostly done and the bridge posts are pre drilled. I'm happy to help out if you have any problems.
