My temp sensor is between spark plugs 1 and 3 (front two on the drivers side) and a little above them. It's right between the two exhaust ports. If there are headers on your truck, the header could block the port. I dunno where it would be if that were the case.

The wire is a green wire with a black cloth insulator around it. If the insulator is over 30 years old, there might not be much of it left. It get's kinda brittle over time. It should run down the driver's side of the intake manifold, around the front of the head and down to the sensor. However, on both of the trucks I have, a previous owner re-routed them to between the steering box and the exhaust manifold pretty much just hanging there.
