The EGR valve is located on the intake manifold. If you're having trouble finding it, just look at your new one and then find it's match on the truck. It should come off with a few bolts (usually 12mm). Be sure to scrape the old gasket off and replace it as well, as leaving this on could cause leaks. After you've done this, just bolt the new one on and you're done. It's also good to buy a Haynes mannual for your specific vehicle. This book is less than $20 at most auto stores and gives you step by step instructions on things like this, with pictures.
