Just a bit of advice needed on where to stick the red box! The instructions seem to say they need a clear view of the road. How important is this. Ive got an ideal spot 2/3rds of the way up the frame spa but some way below it would be a coolant hose and then the (fibreglass) belly pan. Is this likely to work? Where are the favourite places to stick them?

PS Any body else getting just a bit excited?
