I'm wiring a friend's lefty strat for 2 P90s, 1 volume, 1 tone and a 3 way blade. I wired it up and everything works,,except the middle position on the switch. There are 8 lugs and I wired 1,3,6,8 together and to the volume lug. I didn't string it up but tapped the pickups to test them. I should get a tapping sound out of both pickups in the middle position if everything works, right?
