Need Wiring Help for Jackson/Charvel Bass

[Treweek]

I've been asked to reassemble a 90's Jackson Custom Concert Bass (Active P-J bass with switch). This seems very similar to the Charvel B3. It appears to have been a VVT with a switch (pickup selector?) Everything is completely disconnected and there are at least a few parts missing. I could really use some help figuring out how it's supposed to be wired up, since I have found nothing online and contacting Jackson wasn't helpful.

Can anyone help me out with either:
A) A wiring diagram
or
B) A few pictures inside the cavity of a bass with the same VVT with switch layout

Thanks in advance!

(This picture is not the bass I'm talking about, but it has the same control layout, which actually seems to be somewhat rare)

An active bass most likely would be volume/bass/treble/switch, not VVT.

This is the circuit that suppose to be there. This is an active preamp with treble, bass, plus a vol control and a 3 way switch. The preamp is JE-2000.Sadly I didn't manege to make my preamp to work. It was not functional. In ebay you can find an exact replica of this preamp or just replace it with something else. Now my bass is wired passive, with some Seymour Duncan pickups, but the original passive pickups are really good and I'm on dilemma to put them back in My bass is Charvel 850XL

Edit: Main is wired Vol/Vol/Tone/3-way switch to fill the hole , like Explorer guitar.

BTW... what does the 3-way switch do?

Selecting the pickups. P or P/J, or just J. The thing is that there are two volumes to do the same thing. But I left the switch to select the combination I want on the fly. Search google for wiring an Explorer and you will find the schematic. The downside is that if you turn the one volume all the way down it acts like a master volume and mutes the signal. But this is the way it is.

Ok. I'm probably going to end up getting the JE-2000 and wiring it back up to original.
