Just a schematic for a 2 pickup bass with series/parallel switch, pickup selector hpf and lpf, I think I've got everything right just wondering if anyone can point out something I might have missed

Put the volume pot before the LPF tone section. Or, your tone pot will affect volume a lot.

Think of it this way:
Your signal goes through a high pass filter to cut the lows.
Signal now has highs and mids left.
Use a high pass filter to send highs to ground. That cuts out the highs.
Mids are left before the second filter.
Use a volume pot parellel to the second for your output.
That is how you can passively wire for high cut and low cut.
Any resistance inline to output affects volume.

When you size the components for low cut, figure in the 250k from the volume to ground. You might want a 500k volume pot.
I'll recalculate it to take that into account, wouldn't having the volume in parallel with the the lpf mean that now the frequency is fixed and the pot controls attenuation of frequencies above that as opposed to having a sweepable frequency
The path to ground through the volume pot is a fixed resistance. It is parallel to the 50k+500k pot(HPF), so reduces the total resistance to ground in that section.
Yep but the lpf now has the pot and cap wired in series so the corner frequency for the lpf will be fixed by the cap and overall circuit impedance, if the output came from the node between the pot and cap the frequency would be sweepable with a 6db per octave rolloff

There's an English-language glossary on the last two pages which should help get you through the wiring diagrams. If you want to read the rest of the text you'll probably need an online translator.
I just tried using Word. The whole document is too big for Word. You should be able to pick the page you care about, and translate that.
I've been using DeepL, an excellent translator IMO. Looks like they translate document types, too, but haven't tried it. And it's free.
I just copy and paste statements from the German pdf referenced above (an excellent resource, that document).
For instance:
Der Fender Cabronita Precision Bass von 2013
Basis des Cabronita Basses bildet, wie beim La Cabronita "Porrazo", ein 51er Precision Bass.
Die Potis sind jedoch ohne Kontrollblech von hinten eingelassen und das Pickguard hat eine
andere, wesentlich kleinere Form. Als Pickup dient ein Fender Fideli'Tron™ Bass Humbucker,
die Brücke ist eine Fender "Hi-Mass" Bridge mit vier Saitenreitern. Der Erle Body des Fender
Cabronita Basses ist, bis auf eine Abschrägung auf der Vorderseite, nicht konturiert. Der ein
teilige Ahornhals, mit P'51 Kopfplatte hat die Halsmaße des "modernen" Precision Basses.
Turns out as:
The Fender Cabronita Precision Bass from 2013.
The basis of the Cabronita Bass is, like the La Cabronita "Porrazo", a 51 Precision Bass.
However, the pots are recessed from the rear without a control plate and the pickguard has a
different, much smaller shape. The pickup is a Fender Fideli'Tron™ bass humbucker,
the bridge is a Fender "Hi-Mass" bridge with four string riders. The alder body of the Fender
Cabronita bass is not contoured, except for a bevel on the front. The one-piece maple neck, with P'51 headstock has the neck dimensions of the "modern" Precision bass.
