Hmmmm Mine appears to have an extra thingy on one side, seems to be relay or something which is connected to the loom with 2 vacuum pipes, 1 connected the other which has been cut which i've blanked off. any idea what its for?

I'm not sure if I need this hose either, Its been blanked off, it appears to go to the air pipe but I ain't running an airflow meter (Running a Link instead of the factory ECU), pulling the blanking pipe off makes the motor rev more at idle....

Want some of the bolts for the outer covers as well as I'm missing some.....4 would be good
