The lines that plug into it in the rear.... It wraps through and makes a loop on the other side of the coolant hose.. there is a larger looking one closest to the drivers side, and one slightly more tword the passenger side... what the hell plugs into the one more tword the drivers side? We absolutely cannot find anything missing, except that the little adapter there doesnt plug into anything.. We spent a good 20 min searching for something on all parts of the motor before and then after we put that back on..[:@]

 

never mind... found it in a manual for the holley intake. looks like it routes back to the PCV valve...

 

so you have the systemax intake? what is a throttle body size that fits on it?

 

Nope.. have the stock upper intake... that was the only manual I found that actualy had a picture and description of where the vaccum hoses went to.. had to read about 7 of them to find one that actualy told me where that damn line hooked. Think it may have been an open vaccum line.. might explain why it had some idle issues... lol
