    Already posted this in gps forum but I figure I might get a better reply in here.

    Trying to install a gps tracking unit to my vehicle. Ive got four wires,

    1. 12v -
    2. 12v +
    3. Accesory -
    4. Accesory +

    I could rebulid you an engine but i know near to nothing about auto electrics. It looks like a relatively simple job but I just dont know how to do it. Where should will I find these power sources? Any help?

    Thanks

    Do these things remain powered up when vehicle switched off or do they remain powered for a set time or do they simply switch off with the key?

    Cheers for the reply.They remain switched on constantly but a signal is sent from the unit when the ignition is started. Am I right in saying the acc connection is the first turn in the ignition?

    That's right, and the 12V+ is a permanent feed straight from the battery. You should be able to find both the 12V+ and the Accessory+ going into the car radio, and somehow splice the feed to the tracker off of them. The -ve leads are both ground.

    Great. Can I just bolt the two ground leads to the chassis together.

    Yes, there might even be a convenient bolt or screw nearby you could use.

    If its an ISO plug at the back of the radio it makes it even easier... pop out the power ISO plug, get a pin out diagram and work out which wire is which...

    Then splice onto the 2 wires using snap lock connectors....
