Help with vacuum lines
 

So quick run down motor went bad in 1998 GMC k2500 (5.7 vortec) had a guy come over and swap a motor in it (from a 97 k2500 hd) same exact motor. But the guy left and looked nothing up! Trying to find out where vacuum line (the big one) on the evap canister goes, and where the line for break booster goes any help would be awesome.
