Right i blocked off that vac pipe but yet my idle was still far too high, i could just put it in 2nd gear lift off clutch and accelerator. And my car would keep rolling by itself lol. So did a search for high idle and i found out how to adjust the idle screw. Now sits at the mark below the 1k. As for that connector to do with my Brakes.

The connector was actually plugged into it, But the wires have been cut off, Anyone know where the wires from there are meant to connect too?
