Here are some pics of exactly where its at in an 06 GXP. I'm not good with fixing cars and took me 5 mins to replace and get everything back to where I started.

All you need is a regular size flat head screw driver. Use it to pop off the retaining clip that is right underneath the passenger side wiper. Take off the windshield wiper hoze and peel back the plastic piece that you popped the retaining clip off of. After you peel it back you cant miss it.

Here are the pics:
