s5 turbo 2 knock sensor
 

hi there im having a hard time finding anything on a s5 turbo 2 knock sensor on here.
i had a s5 13b na in my car but have now swapped it out for a s5 13b t2 i used my na wire harness everything has connected well so far but im wondering how to wire in the knock sensor or if i even have to wire it in. and there is also a 12v sensor with 2 hoses coming off of it on the top right side of the motor that my wire harness dosnt have a plug for does anyone know what that might be for?

thanks so much for you help.
