    S13 ISO block and aerial adapter reference numbers

    To all fellow ICE newbies:

    The code numbers and following advice relate to the adapters required to change the standard Clarion head unit for something more sexy;

    PC2-13-4 for the ISO Harness adapter and

    PC5-87 for the antenna adapter

    + when fitting wire the black earth wire from the ISO adapter directly to chassis of the car, as there is (confusingly) no earth lead in the nissan standard connectors.

    Note: until you wire the earth in to the chassis the unit will be 'live' from the power backup memory lead - which is always on for obvious reasons - which is why the electric aerial goes up ! Don't panic, it will behave itself properly once you have wired the black wire to earth.

    For further fitting advice also see

    The best price / source I have found for both the ISO kit AND the mystery adapter, purchased as a discounted kit together is

    http://www.nexxia.co.uk/Car_Stereo_f...ssan/200sx.htm

    The ISO kit can be found on egay on its own for about a fiver combined price + postage

    For the antenna adapter alone egay draws a blank. The best price I have found for the adapter on its own is

    I would just say that it's a really good idea to disconnect the battery before doing anything like this.

    On most cars it's relatively ok to connect/disconnect the headunit, but the lack of earth makes this advisable here.

    Also, you may need to earth the outside of the headunit seperately. I've seen ISO adapters that include a wire to do this, but whether you'll need to or not is something you will have to test with a multimeter after installation If you don't get continuity between the metal of the headunit and the chassis after it's fully screwed down, then you will have to pull it out and make an earth yourself - the bolt on the back which isn't needed because it's a japanese car should be quite handy for this Having said all this, the metal case should be earthed via the mounting plates, but you never know, it's best to spend 30seconds checking instead of wondering why there's lots of noise coming through the speakers Don't make a seperate earth connection to the chassis of the headunit unless you have to, that way lies ground loops.

    Good advice to disconnect the battery while doing the job, I agree.

    But not sure what yout mean by

    All I did was connect the black earth lead going from the new stereo head unit to the ISO connecter block to the chassis... Not a new or separate earth connection as I see it, nor one unintended by the manufacturer.....

    And what the hell is a ground loop when it's at home ?

    It's where there's a loop formed in the ground circuitry that acts like an antenna. It picks up all sorts of noise, especially 50Hz hum from mains electricity which is all around you, and produces an annoying whine from the alternator.

    You wouldn't think this would have an effect would you? What happens is that instead of the signal producing sound relative to the ground, the reference ground itself moves and super-imposes on top of the normal signal.

    You need to wire in an earth to the head unit Cut the black wire on the adaptor and extend the radio end of it down to one of the gearstick rubber gaitor bolts Works a treat

    Just so people know, Have found a few places on ebay that do the twin pin aerial adapter for much cheaper than halfords (15)

    I'm running an ISO adaptor without an earth wire. As far as I can tell the earth is though the antenna shield, I have a proper Diversity adaptor. Antenna works as it should.
