Answer 1

back of the motor, toward the right. It's a round thing with one air line coming off it. you can put your fingers underneath it and push up the diaphram. it's secured to the block by 2 bolts.

Answer 2

It's on top of the motor either mounted close or on top of the intake manifold. It will have an exhaust pipe snake to it depending on the different motors. It is usually black, sometimes with a plastic black cover and about the size of a clenched fist. It has four wires running to it as well.
