its connected to the S terminal through a diode, so when you power the relay, it also powers the I terminal. The diode is there so you don't back-feed the thing and keep the starter relay pulled.
On Duraspark cars, its there to bypass the resistor wire or ballast resistor. Stuff in the 80s may have been wired in different ways but thats what you'll see on 70s stuff.
