    hi guys hope someone can help...after searching the forums and reading the below posts

    http://www.bimmerforums.co.uk/forum/...272/page2.html

    http://www.bimmerforums.co.uk/forum/...nction-t35837/

    ive got the 7 button obc wired in and working in a fashion.... theres some differneces in the woring colours of both guides and they dont really match my wiring either.....

    so far ive got the
    purple wire wired switched live
    red/white perm live
    grey white wired to lighting circuit
    brown to earth......

    clock and lighting etc all work fine....now the temp sensor.....on the above guides it mentiions green wires and various other colours....all i have left now is blu/white hooped....blue/white striped.....black /white...and brown grey......

    now in one of the guides it says to use the brown grey for the sensor which would match the wire on the sensor i have the other wire on sensro is brown and orange....now does the other side goto earth or to one of the other colours ive tried all manner of ways but nothing seems to work.....

    im no electrical genius but i did try and test the temp semsor on a multimeter and found if i warmed the sensor the readings dropped and if cooled they raised so i presume the sensor works fine...is it ??? .....

    any help please appreciated as i really dont want to go back to anologue clock .....

    cheers...andy
