13 Pin towbar electrics

Struggling with wiring the 13pin plug on a Discovery 3 due to the colours of the wire not corresponding with a standard 13 pin colours. Was wondering whether anyone has a Land Rover wiring diagram for the socket or loom used?
Cheers

LR use the standard UK vehicle wire colours to its connectors and for instance black generally denotes earth wires. Aftermarket use ISO 11446 for the 13 pin socket wires which mostly relates to the wiring in the trailers and base white is earth

Thank you for your responses. Never normally had a problem wiring these in but this is causing some confusion!
The colours of the wires used for example are:
Red/brown
Yellow/brown
Red/blue
Black/white
Red/Grey
Green/black
Along with the standard block colours used as standard.

So I can assume it must be an LR loom? If anyone can help with the colours it would save me using a meter to distinguish!
Cheers

Loom was functioning perfectly with a 13pin plug on. The socket was taken off to replace with a new 13 pin as there was minor corrosion on the pins. No noting was carried out to where any of the wires went assuming it would follow the standard 13 pin wiring. Having fitted looms to Discos before it has obviously been sold as a complete loom rather than homemade but the colour of wires doesn't at the moment make a great deal of sense!
Cheers.

My post above linked to my previous post with a full pinout of the 13 pin socket with LR colours.

Edit: your colours don't seem to match the LR colours, so you likely have an aftermarket loom. You might have to end up to either test each wire with a meter to see what it does, or unplug the other ends and see where the various colours go to in the 3 upper sockets.

Thank you all very much. Would appear it is a PF Jones loom! Should all be sorted next weekend all being well.
Cheers Dylan.
