Engine shut of is a very simple vacuum switch mounted to the ignition switch. Your 380SE might even carry one along that is not needed, but I doubt it unless the ignition assembly has been replaced by a used switch. But anyway, install a used switch body with your key switch installed, and make sure it has the vacuum hook up. Then of course you will have to run two vacuum lines, one from the vacuum source to the switch and then a line from the switch to the shut off on the injection pump.
