stk 403 130 mute question

hi , it is power amplifier module from sony micro system.
on 16v unreg i put 16v with 200uf
on protect 3.3v from 7833
on relay b+ 12v from 7812
on stk mute i am not sure what to do,should i conect it to v+?

7833 is powered from 7812,7812 is povered from unreg 16v .
thank you.

EDIT: 16v unreg needs 16v, from that 16v you can connect 7812 and feed relay b+,stk mute is then feeded from 5v to enable mute,protect does not need to be connected
