Hi - I have a vauxhall Cavalier 1991 - Need help with wiring the immobiliser circuit on my cliffrd concept 650 - The ignition key has 5 wires - 1 is constant 12v two other black wires become live when ignition is on and then the starter wire - also there is a thin grey wire. The harness from the brain box has 4 wires - 2 split the ignition and 2 split the starter. Any help on which wires to connect would be great as i cannot work it out - thanks in advance from shaun. The instructions are telling me to locate the ignition and starter wires from ignition - ive located the starter wire but which would be the ignition wire on the car wires ????
