In following the Starting Aids Tour, I note my 1966 230 SL should have a time switch (which I believe should be cylindrical) next to the other starting system relays. I note there are two unattached wires, but no time switch. I've tried all the typical sources (Bud's, Eurocars, AutohausAZ, etc.) but haven't been able to locate this part. Does anyone have any suggestions?
