Can anyone help, just bought an Xr4x4 to tow my 3dr to shows etc, have fitted a tow bar on it but dont know which wires go where?

I know what the colours from the electric point on the tow bar are (yellow - left hand indicator, blue - rear fog, etc etc) But dont know the corresponding colours in the rear light wiring of the car?

Am after the wiring colours in the rear clusters if anyone knows them off the top of their head (saves me testing each wire cause am lazy )

Cheers!!
