You need tocap the pink line and T into the line coming off of the throttle body.

 

Turns out the spring was too hard, I swapped out the spring for a lighter one and it works a lot better. nice and smooth. I thought about doing that too (putting a "T" on the TB vac line.) thanks for the input.

 

Youshould reallychange it up ... the pink line doesn't see enough boost to operate your BoV properly.

 

or just get a real bov [:@]
