exhaust by pass controller location

Hi, I'm sure this may have been covered before, but I've bought a forza controller to fit on my 2016 CaliT if someone has done this already where did you place the controller? i was hoping under the tool /tire pump box but everywhere im looking already has some bit of kit. it says to fit someplace dry which isn't leaving many places left, thanks Simon

 

Hi thanks for your reply you would have a picture of the location you could share have you ? Regards Simon
