89 Century MAP Sensor Location?

Hey, after doing some trouble shooting, i think my MAP sensor might be bad and i want to test it, however, i am having trouble finding it. Usualy its attached to a bracket (on the firewall) or between the FW and the engine block it self. However on this car, its no where to be found, i've spent an hour or so looking for it with no luck.

Does anyone know where its located on an 89' Century? i thought it would be located in the same place as my Cutlass, but its not..

Any help would be great.. Thank guys!
