Tow bar wiring Avensis 2004

[Martyapple]

 Hi all, this is my first post on the forum. I need a circuit diagram. of the back light cluster so I can wire in my new tow bar. I have a 7 way universal Bypass relay, with instructions but it doesn't give me the back light cluster wires colour. i.e. what colour is for the brake lights etc. Can anyone help? Thanks.
