I am looking at fitting a set of rear parking sensors to my 2006 Mazda 5 and wondering where the factory fitted sensors are located. Does anyone have them already fitted who could recommend measurements or provide a picture to help me position them ?

Also any advise on colour coding appreciated. Have heard that I should only use a few light coats of spray paint and laquer. Should I key them slightly first and maybe use a primer too ?

Any help appreciated :-)
