Guitar Question: Pinch Harmonics Settings?

Have your guitar switched to the bridge pickup with the volume all the way up. Have a nice distortion setting going, and boost the treble on the amp to at least the five o clock position or more. Hold the pick like you normally would, but slink it back a bit so less of it is sticking out between your thumb and finger. As you hit the string, tap or brush the string with the bottom of your thumb tip as it goes past. It takes some practice, but that should make it easier.
