Power Steering Fluid

This may seem like a stupid question, but i cant find the answer anywhere else. I have a 1994 gmc sierra sle (5.7L V8), and i need to know where the power steering fluid goes. All the lettering on things like engine oil and coolant are worn off, and i really dont want to put power steering fluid in my transmission fluid instead. thanks for your help.

The Power Steering pump is driven by the serpentine belt and is near the drivers side head.

When you remove the cap, it will have a dip stick built in so you know how much fluid to add.
