I recently took my truck to the dealer and they said it system has failed and needs to be replaced. I have found on here that I can disconnect the system and have found diagrams but they are all for the 5.7 :cry3d:. Anyone have a link to a diagram?

You'd be better served buying a Unichip module, installing it, and finding a local dyno shop that has Unichip's "Custom Tuner Kit" and simply bypassing the AIP signal.
