Help - Rear light clio MK3

[amarsh360]

Hello... Anyone know what one of these colours is the reverse light on the Clio MK3 drivers side (if the side makes a difference?)
Trying to install a reversing camera on my gfs car and the nagging is getting unbearable now... help a brother out... Cheers!

Put a volt meter on the pins and see which one goes 12v when you put it in reverse

Use a test light to find which one it is mate

I can't remember the colours off the top of my head

Took your advice, used a volt meter - in case anyone else needs it, the ground is black and the reverse is the orange next to the green.
Thanks for the advice guys
