I done mine a few months ago (2014) I might have the colours somewhere but they are different from what I found on the internet. Make sure you use a smart relay for the wiring I took 12v for the smart relay from my battery but there is 12v in the boot at the passanger side. I took the connector of the light units and used a multimeter on the connector pins to get the correct wires for each light.
I'll have a look and see if I can find the wire colours when I done it.

wiring prob

thanks that would be great if you have them to hand, thought of using meter but was not sure it would work due to the electronics

It works fine you just need to make sure you use the smart relay, I found using the meter on the rear light connectors was the easiest way to do it as when I searched the internet for the wire colours some matched but others didn't.

Here is a guide for the bypass relay https://www.towsure.com/fit_a_multiplex_bypass_relay

I can't find the wiring from when I done mine but as I said just use a meter on the back light connectors.
