    Hi, so I obtained a set of the piaa lights that you could get which were specifically for the classic impreza.
    There is a relay box, what looks like an earth coming off the relay box, a long protected wire which I assume is the positive, two connections to the spot lights, what looks like another earth and then what looks like it was a signal wire. Will get a picture.
    I connected them up to a booster pack to test my thoughts but nothing.
    Does anyone have the wiring setup for these?
    I have read that there was also an option which disabled them unless the front dog light switch was on

    1 wire: +12v from the battery, normally with a fuse.
    1 wire: +12v Switched wire, normally spliced in to the +12v mainbeam wire.
    1 wire: Too the lights.
    1 wire: Earthed.
