    Looking for a live wire anybody help

    Hi all
    i want to fit an led in the dash to act as a further deterrent to the light fingered people
    problem is im used to fords and on their ignition switch in the off position there was a live that worked then but went off as soon as the ignition was put on hence ignition on no flash and ignition off led would flash
    big question is does anyone know if my astra g has a similar terminal that i can use
    i dont have a standard alarm on the car and i live in a low car crime area so just want the deterrent really
    i have thought about a switch but im bound to forget to put it on
    thanks all
    rob

    Wire the live to any red wire (Permanent +12v) and the negative to a black wire which is +12v when the ignition is on but earth when its off.
    The truth is always the truth even if you haven't realised it yet...

    Hi there
    thanks for the reply
    will that not damage the led or blow a fuse when ignition on as there will be 2 lives as such going in
    so what your saying is use the switched ignition positive feed to the radio possibly and also the permananent backup radio wire for the positive as the switched one should go to earth when ignition off
    is that right?

    hi there
    ok excellent thanks
    got to hunt the live that goes to earth then i guess, i will find the permanent live first and use the test meter to find another live then switch ignition off and see if i have 12volts still on the meter
    does that sound right as im being thick tonight
