Good morning...I am not an electronics whiz at all but I need to replace and rewire the neck selection switch on my Mullen D-10. After reviewing other sources, I came up with this rough sketch. It does not have tone control. The previous owner had some unprotected solder connections making contact with the undercarriage. I am able to solder and such, just not sure about the wiring scheme. Does this look correct? Thank you very much!

Jack, my best guess is to find a stationary metal component and attach the ground there. Like you, that is part of my dilemma. I have never been good at working on or diagnosing electrical devices or issues. Hoping someone will chime in for us.

I believe that would be the best place to ground the jack and pickups. Again, hoping someone takes a look at this for us.

Every guitar I have ever owned is grounded to the sleeve of the jack. Never have I seen a wire going to any place else.

Thanks, Richard...that will help Jack and I out. I had a mass of wires just hanging underneath mine with a glob of solder on it. This is a recently acquired Mullen.

My Mullen grounds the pickup to the jack.

The changer should be grounded to the endplates by a piece of wire. This assures that all the physically-connected but non-electric metal parts are also grounded.
Also, I'd add the connecting wires shown below in red so all the switch contacts are redundant. That's standard practice, and keeps everything working if one of the switch contacts goes bad.

Perfect...Thanks so much for the response, Donny!
Jack, this may help out your question as well.

Then why don't builders do that? I think most guitars, the changer does contact the end plate, even if only by the lower return springs.

| True, on most guitars, the springs do attach to the end plate. But it's not true of all of all guitars, so I recommend it just in case. |

Good point.
Just out of curiosity, why would the changer need to be grounded to the end plate? There shouldn't be any electrical current in the changer. Just curious.
