Check if you can do this..
Neck only on positions 1 and 2
Neck and Bridge on position 3
Bridge only on positions 4 and 5
This is how my guitar is wired as it has a 5 position switch which originally had coil tap on P2 and P4. Leaving P1 or P5 as muted can be pretty bad; especially if you hurry into a solo in the middle of a song...
