Hello, I just bought my 2nd 300D i has a few issues, one of which is that it wont shut off and the hose coming off the fuel shut off is hanging free. where does it plug into and if I apply vacuum to it it should kill the engine unless the actuator is bad right? thanks

That line, brown/violet, should go to the ignition switch. Yes, if you apply vacuum, it should shut the engine off if it's good.

you should fix it or otherwise you are gonna be popping the hood everytime you want to shut if off

One tool which is gonna be a huge help is something like a MightyVac.

thanks everyone so that brown/violet line goes through the firewall directly to the ignition switch?

Yes, as does a brown line getting a vacuum supply from the main line.
