The International dealer is a good place as well, stay away from Ford. Its located in the middle of the front of the engine. If you look from the passenger side down following the belt down, you'll see a bronze pointer for timing marks. Thats the sensor. If your truck is older, might want to check it out ahead of time. 10mm 1/4" drive socket and a flathead screwdriver if you are lucky. Its a pain the first time and if you have no problems with the little bolt, its like a 5 min job. My last replacement was a 4-day job because of a seized bolt. It was stripped, had to get bolt-outs from Sears to remove it. Replaced mine with a 1/2" instead of 10mm and used anti-seize again.
