under your hood there should be like 3-6 scews that hold it down remove them and your wipers and it should come off. Might have to pay with it though IIRC you have to kinda push/bend it on the end to pop it up.
It was very easy. Like you said, 3 plastic screws, pull off the hose to the squiters, twist each end to clear the pillars and it was out.
