Diagram of where the crankshaft and camshaft position sensors are needed?

Yep, they hide it from you on this truck, the crankshaft sensor is inside of the access port for the torque converter bolts which is on the left side of the engine down at the bellhousing. You will need to remove the skid plate and a bracket to get at it. Here is how the job is done and the location of the sensor. Check out the images (below). Let us know if you need anything else.

My bad, here is the camshaft sensors as well. They are at the rear of the cylinder head. Check out the images (below). Let us know if you need anything else.
