    Electrical Schematic - SL35

    Hello to All

    I would like to know or have someone explain to me the purpose(s) of the following items on schematic SL35. Also, how & if these items have any relevance or concerns I should be aware of on a 1970 2.2 litre 911T:

    #11 - the purpose & function of the speed switch
    #12 - the electromagnetic control valve
    #13 – lifting magnet

    Thank you for your help & inputs
    Cheers
    JB

    It is emissions related . When coasting with the throttle off between certain rpm's the idle circuit is closed .

    And I think they are only used on MFI, not carbs.
