On that switch you posted, one set of three contacts are for the three pickups and the other three are for your tone controls, the contact in the middle of the switch is common to both sets of three contacts and is normally connected up to the volume control, I'll draw up a diagram to illustrate my point.
Yes the middle contact to volume is correct based on what I can tell from the remnants of previous wiring. And yep 3 contacts and three pickups makes sense, although the top contacts have never been used. If you look in the switch it does a bridge between contacts in the 'between' position.
