VSS Wire 2000 Impala

Hi, i have a 2000 impala ls 3.8L.  I looked up the location of the vss wire on this website and it said that it is a green wire in location 15 air filter box yellow 80 pin conn position 54.  I took my air filter box out and their were two sets of 80 pin connections.  However, the one set of them were blue and the other set of 80 were white.  Both those were directly underneath my air filter box.  I tried finding a yellow set but couldn't see them anywhere. 

Does anybody know if I am supposed to use the blue or white set, or if there is a yellow set, where it is at?  Any help would be appreciated. 

try the BCM. The BCM is located above the brake pedal. It is a plastic box with three plugs that face the firewall gray 16-pin plug use the green wire
