Boot trailer socket kit??

I have bought a boot trailer socket kit but the wiring colours do not match the wiring colours on my car..1996 nissan pulsar CJ1. I recently got a tow bar installed but need the wiring kit to beable to tow a trailer...any ideas? The kit is made by ARK and is a 7 pin flat socket connected to 1.25 metres of 7 core flat cable.

Thank you for all that has helped...NOT!!I have got my problem sorted thank you.
