Mass Air flow meter is inside the air filter box. You need to pop off the rubber cap with the wires running in it in the first picture link you posted. Those are the wires going to the mass air flow meter and you need to disconnect it from there.

At the front of the air box, loosen both screw clamps (one on the small plastic pipe going down to the air pump and the other one and the other one on the Samco hose), then pop off the rubber cap on top, disconnect the mass air flow wring, and then pop off the clamps on the side of the air filter housing. There's probably 3 or 4 clamps. Take off the top part of the air filter housing and looking underneath and you'll see the mass air flow meter.
