^As I said, the bridge tone only works in P-1, in all other positions the other tone pot takes over.
In P-2 the bridge and middle are connected to the neck/mid tone:
Bridge Hot >> C-2 >> C-COM >> D-COM >> D-2/3/4 >> B-2/3/4 >> B-COM >> Tone Pot
Mid Hot >> D-2/3/4 >> B-2/3/4 >> B-COM.
If you want the Bridge Tone to work in both "Bridge on" positions, connect the bridge tone across C-1or C-2, which are linked so it doesn't matter which.
By extension, if that works, you could connect the mid/neck tone to C-4/5 and D-2/3/4 and do away with Bank B entirely. I'll have to look at that later today.
