The evap sol. also on the top behind the TB.
Also, the passenger side valve cover goes to a hose behind the TB.

If you need an extra vac line (you're probably looking for a vac leak though) you can break off the tap on the pass. side intake, towards the back, just an fyi.

Also, if you had the intake off, you could have a vac leak there as well.
Find a shop with a smoke machine, it pumps smoke through the engine and intake at about 1-5psi, works great for finding small leaks.

good luck,
