Cold Start valve electrical feed on 1969 280SL

[rutger kohler]

Hi, The solenoid valve I am referring to is the the one mounted on the inlet manifold that squirts the initial petrol/gas into the manifold.  In the wiring diagram in the technical manual, and other literature it is suggested this has a relay. If so where is this located please, or the the electrical feed direct from terminal 50 on the ignition switch?
