Reversing sensors

[Terranical]

I may have asked this question before, so if I have I apologise in advance (senior moment!)
I have a set of four reversing sensors that I would like to fit to my Terrano but am unsure about their positioning i.e. will they detect the tow bar and/or the spare wheel.
I dont want to drill 4 22mm holes in my bumper, then find the sensors are beeping all the time the car is in reverse.
Has anyone fitted these, and if so where did you position the sensors, and did you have any problems with false warnings?
Cheers
Bruce (Terranical)

i tend to use the bang type sensor .... when reversing if you hear a bang or a crunch , or even a scream , youve hit something / someone :augie

on a serious note , if you look at the thread below you will find pics of a member ( ex member ) who fitted them to his truck :thumb2

Thanks for that Briggie, answered all my questions (don't know why I couldn't find that thread, another senior moment perhaps!)
