reversing sensors

[davetyler]

I have some reversing sensors that i am trying to fit on a 206cc 2002.

First of all what is the best way to measure the spacing etc i have four sensors to fit. Where is the connection for the reversing light. I have pictures for fitting three sensors but not four.

Is there a website to help???

cheers
