dozin's 5 way wiring is correct for the shared 500k tone potentiometer. that's why it's wired that way. the 5 way is double poled. so, it has two sets of lugs that do the same thing laid in opposite of eachother. the pickups are wired to one side in order and the 4th lug is the output. on the other set of lugs, the neck & middle pickups are jumpered over and that 4th lug is used for the shared tone control. since the neck and bridge cannot be used together with a 5 way wired like this, that tone control will not be used simultaneously with another pickup tied to it. it's actually how i believe rosebud & bolt are actually wired with their humbucker neck pickup. tiger, wolf and the travis bean 500's were wired with a seperate tone control by using a dual ganged potentiometer. the wiring would be the same MINUS the tone control jumpers for the neck and bridge, and the 2 tone controls left would tie directly to the neck and bridge lugs on the 5 way. just like the middle pickup and tone control would be wired. this would leave one set of lugs empty on the 5 way.
another thing to note about that schematic is where the ground lands for the bridge pickup tap switch. it is on the empty set side and should be on the lug directly beneath the wires from the bridge pickup.
aside from that, if you didn't wire the 5 way like dozins schem, you might have problems.
