Nats 2

Hello I've just joined as read that a wiring diagram exists to by pass a Nats 2. I have a lovely 95 Micra that I will have to scrap if I can't by pass. Its such a waste and money I haven't realy got to buy another car. The immobiler isn't the one with 8 wires this has around 12. Thankyou for my help if anyones in the know of how to go about by passing it.
