Hi there and welcome to GM Trucks.

 

There are probably a few descriptions here in the audio forum that talk about adding an amp in trucks like yours. I know there are a few threads that do have pictures. You can ground to a seat bolt, a seatbelt bolt, or any secure location. Just make sure that the there is good contact. That is no paint or anything getting in the way.
