Does somebody knows.....?

[trb4p]

Hi guys!
Sorry for my english,i'm an italian guy and i'm learning it.
I have a Yamaha Trb4P and
I've broken my mini-toggle switch.
I've lost the 'original' toggle, and all the cables
and connectors.
I've acquired another toggle-switch, but no one can
tell me how i have to connetc the cables on the electronic circuits inside my bass.
Is there someone that posses a Trb4P-Trb6P,
and, in opening it, can tell me how to connect cables on the 5-pin connector on the circuits & on the toggle?
Thanks a lot, men.
Nobody know that, in Italy.
Bye.
Dave
