help with 74 450sl: electrical and cruise questions

I have a 74 450sl and have a couple things I need help with.
(1) Four of my cylinders cut out on me sporadically (#s 1,4,5,6). They lose power to the fuel injectors and I don't see a common circuit for them on the schematics. If someone can help I would appreciate it. I've tried finding the Electronic Control Unit (ECU) to check connections there but I can't locate it.
(2) On my cruise control, the diagrams show a single vacuum hose attaching to the Servo/actuator unit. Well, I just happen to have 2 vacuum hoses, one of which simply ends and is hanging free between the firewall and the back of the glove box. Any ideas where this goes?
Thanks for helping if you can.
