Selector Switch connections on Vibra Artist

Hope someone might be able to help. I disconnected the 3 way switch on my Vibra Artiste a couple of months back I marked with masking tape where the wires went on the switch. Unfortunately did not do a good job and tape has come detached so do not know which wires connect on which terminal. It is the switch with the bulbous housing and it is not clear like on a Telecaster 3 way switch. Any help much appreciated as do not want a shocking experience. I have to say the Vibra Artiste wiring is very complex and the pick up wires are as thin as the hair on my head and I am bald
