I was about to chime in and say just that, you might also need an additional Relay depending on how many circuits the diagrams shows as starter circuits... so head down to a local Best Buy with an Install Bay for car electronics, and they can tell you exactly what you will need as far as parts go.
Also I HIGHLY suggest an ignition immobilizer bypass that requires a physical key connection, instead of a "programmed" connection as sometimes the fully electronic ones lose their programming, and then your truck wont start. (I suggest the 556UW)
