Yes, what you say is correct, although I'm not sure why you are focusing on X- Y- (26,7) at the expense of X+,Y+(24,25). And, naturally, these 4 pins are bordered on BOTH sides by a ground pin...

It is fun, mind you, designing and building all sorts of nifty gadgets, etc... and (when possible) repairing the odd bit of electronics here and there for friends & family...

If the parts are the same in the N810, I can slip you a copy of the N810 schematics (the N810 ones is in perfect quality)

I'd appreciate the item qwerty offered as well. It appears the forum supports file attachments and links.

Ok, well, largely thanks to Briand, plus finally being able to at least discern a starting "C" from a starting "R" on the blurry schematics, along with some deduction, I know precisely which three components I need. I nearly lost my eyesight yesterday trying to solder a scavenged 1meg resistor into place (sort of), but now think I'll adopt a different tack and see if I can't attach an auxiliary mini-board with larger components, attached to the three required points (+ ground) using very fine magnet wire, perhaps. I've found a little "pocket" where I could place this. I won't get to this for a few days, but I'll post back my results.

good deal!
would love to see a photo of the finished work, as well... and I promise not to criticize your breadboarding technique.

you could accidentally slip that copy towards me, as well, and you'd not hear a peep of complaint!!
