toad alarm on a 172 PH2

[shiwarrior]

Hi , odd question this, but where do they put the valet switch ? do they cut a hole next to the ESP button? does it look ok, or should i get the plastic part that has 3 holes from the 182 model ? (if they have 3 that is)

i should be getting my alarm fitted and want to know if i need to get the plastic bit with 3 holes already made or not

thanks
