Would someone be kind enough to make sure I’m good before executing?

What’s involved:
(2) Delano HE/S pickups, 4-wire

Plan/Goal:
V-V-T passive.
The bass I have planned for this includes 4 knobs for potentiometers. 3 will be actively used, 1 will be a “dummy” of sorts; the push-pull will function, but the pot will not be used/hooked up. Will be a “producer” knob, if you will…
V neck =250K linear taper
V bridge =250K linear taper
T master =250K audio taper push-pull. Push for parallel, pull for series (bridge PU).
Dummy = push pull pot, but will only be used for the switch. Push for series, pull for parallel (neck PU).
here’s a pic, I modified the Delano install guide please let me know if there is a mis-step here…

Thank you for reading my post. Would definitely appreciate it if someone with a stronger understanding of electronics could make sure I have this correct.

Looks good to me, the only remark is that soldering to he pot is the most annoying solder and the schematic seems to suggest soldering to each pot twice.

I would simply solder the ground of the pickup to the lug instead of the pot casing. But electrically everything looks good.

I think your schematic is good. You're basically doing jazz bass wiring with the switches for series/parallel before the volume pots.

You want your pot casings to be grounded so I'd follow the drawing soldering to the back of the pots. To make this a little easier sand or scrape a bare spot on the back of each pot, lay the soldering iron tip on it to heat the casing, and melt a small pool of solder on that spot first. Then to attach your wires melt the little pool and lay them in it, removing the heat so

Thanks for the help on this. I was studying what I planning to attempt and made a small change, that may be critical:

I'm pretty ok with the mechanics of soldering, but like I said previously, I'm kinda weak when it comes to the function of the electronics. I was reading the excellent tutorials they have on the Lindy Fralin Website and think I have a little better understanding...

Push-Pull Pots - How They Work, Wiring Mods, and More! (fralinpickups.com)

If you could, check out my modification to the left hand (neck) switch. is my first sketch right or is this second one? - Am trying to have the neck pushed in for series rather than pulled out. Bridge in parallel, neck in series is my default setting. Am trying to avoid having to pull out the neck tone knob every time I play...

Ok, so I got this together and it works!
As mentioned previously, I am pretty dense when it comes to seeing how as circuit works. I did switch from series-parallel to series-single coil. I called an audible on that one; literally. When I test-assembled by just twisting wires together before soldering, I thought that the parallel was not as useful as the single coil. - The Delano HE/S does do a really good "Jaco" tone when you do full bridge in parallel, but that was a little too unique for me to hardwire...
What I ended up with is a 4-knob VVT. The bridge tone is PP Series-Single Coil. The 4th knob just uses the push-pull switch without the pot hooked up. There was a hole in the bass, so had to do something with it. I've seen threads here on TB that went on for pages for what to do with that pesky 4th hole...
Reason I didn't just hook up 2 tones is that in a passive bass, if you hook up two tonepots they will interfere with one another. I've had two VVTT basses. If you get one right, and then adjust the other, the first one is now different. I'm probably a little AR on that, but I just like the master tone. It seems Leo was right...

Here's documentation of the process:

It took me some reading, and experimenting to learn that the left side of my push-pull switch is independent of the right side of my push-pull switch. The second two pages are from the Lindy Fralin website. Very nice info they have there, on many topics!
Once I understood that I only needed one side of the switch section of my push-pull pot, it was downhill. Well, except for the actual soldering...
Not to toot my own horn, but I really like the push-pull without the pot hooked up in the neck position
