Need help with hose location and wiring
 

95 Isuzu rodeo,

Problem 1: There is supposed to be a hose coming off of the left side of the intake manifold, it runs across the top of the engine in a bracket hooked to the cable for the throttle, and then goes down on the left side of the air cleaner housing. I need to know where it is suppose to hook up underneith my Rodeo. There is an image in the Chilton for Isuzu Amigo/pick-ups/rodeo/trooper 1981-96 repair manual but it doesn't have the information I need.

Problem 2:
There is no Mass Air Flow Sensor hooked up and I can't find the wiring harness.
