Greddy boost cut controller

[lowey1987]

Hello there

Just got a greddy boost cut controller for my fc3s just wondering were abouts does it fit if any one has experience with these I'm assuming it's near the pressure sensor like the raceing beat one goes but it's not got any instructions and it is going to take a little while to get here so just after options ect any help advise will be appreciated cheers
