When i did my head gasket there was this blue connector at the end of the string on the injector connectors, when i took the engine apart it wasn't connected to anything so i assumed it was for an accessory i didn't have or something.

Thing is that i was poking around on the net and i saw a picture of it plugged in, so i had to find out what it was.

I pulled it up in the haynes manual, and found out that it's connected to a "pressure regulator vsv"

Is it normal to not have this little vsv?

Here's the pic that i found with it on

It's that BRIGHT blue connector that plugs into the right side of the manifold (from the direction that picture is taken, passenger side)

Should i just leave it be, or should i add it to the list of things that i need to do to my mk1 to get it running just right?
