Knock monitor rb26 location

Hi guys anyone got a good recommendation for placing a knock sensor for my audio equipment on a rb26 gtr r32. Stock everything setup, obviously they have very minimal access everywhere, I’m thinking underneath the plenum is going to be my only option even though I don’t really want to. Anyone had an success with any other locations or the best accessible spots?, what are your thought thanks.

the factory spots are the best but generally for tuning with audio i use the cylinder head right front inlet side or left rear

ive been tuning a while and know what im hearing i use the knock link audio gear
