Ultimate FX soundboard swing sensor

[Jonlo Garoc]

My old ultimate fx soundboard has an overactive swing sensor, ergo I'm replacing it. Here's my problem: I don't know which of the two black structures is the swing sensor. If anyone has knowledge of this, it would be greatly appreciated!

if im not mistaken its the black one nearest that left hole (the left black structure i guess i should say). Im fairly certain the right one is a can type capacitor.. if you can read any numbers on it that have "v" or "(symbol for micro)F" then that is a capacitor.
I have no experience at all with soundboards so i may be wrong...
