The knock sensor is between the heads. You have to pull the air intake chamber and the intake manifold to get to the knock sensor. If you're going to do that, then replace the knock sensor wire while you're in there. They get brittle over time.
If you search hard enough on here, you'll find links to a copy of the service manual for your truck (like this one). If you search even harder, you'll find the link to the actual section you need to get everything out of your way to get to the knock sensor (like this one). Your questions have all been answered on here many times.
