There is no functional difference in those two diagrams. None.
Also, when wiring the tone circuit, it doesn't matter which order the pieces are in. Cap to pot to ground, or pot to cap to ground. And it doesn't matter which of the two tone pot lugs is used for the cap.
That said, I'd look into 50s wiring. It's just what lugs on the pots are used for the tone cap
That article of Dirk's is extremely misleading. It implies there's a thing called 60s wiring, and that it's different from what he calls 'modern'. They're functionally
identical. It's like focusing on whether someone taught you to tie shoes by going right over left, or left over right. It doesn't matter!
Also, you seem to have misinterpreted his diagram of 50s wiring. It's not about the tone cap. It's all about which VOLUME pot lug the tone circuit connects to. Normally it's the volume input, so the unaffected signal bleeds off any treble before it gets to the volume pot. With 50s, the entire signal goes through the volume pot, and the output is fed to the tone circuit, where treble is bled off. (No, I'm not talking about treble bleed circuits LOL).
Maybe this will help. In the two grids below, the top one shows standard wiring, and the bottom 50s. There is zero difference between any of the four diagrams in each grid. And between the two grids, the ONLY difference is in the red circle near the bottom. The wire is moved from volume input, to output.
neither of the diagrams I posted have the cap linked to the volume pot
Again, no difference, as you see below. The outermost (let's call it lug #3) of the volume pot is always grounded - it's the only way the pot works. Grounding the cap there is just convenience.
It doesn't matter where a ground connects, as long as all grounds are ultimately connected.
