I bought mine on line when I had my other truck, and it was VERY simple. I had a 2001 F350 with the 7.3, but I immagine there all very similar.
On Pyro I had a plug that I could just take off to get reading from, this truck I had to take exhaust manifold off and drill out for pyro sender, but wasnt that big of a deal. boost is just intercepting a vacume line usually, and tranny there was a plug I had to take out and the sensor went in its place.
Id say about 3-4 hours and about 6 beers for a rookie like me
