Parking activation system

[IronStu]

Hi everyone,
I've got a 66 plate van with parking sensors which are working but when I select reverse, the dash does not show any rear view picture. In the manual it says the reversing camera is at the registration plate light but I can't see it there. Is the camera in the third brake light? Does anyone have a wiring diagram for any of this?
Thanks for your help.

My manual does not mention reversing camera but thats probably because its an older model.

I think unless your spec for your motor is very high you won't have one. There is usually a statement (page 1 on the online handbook) that says you will only have some of the equipment mentioned in this document.
