I just installed a new CAI for my '06 1500 4.7l and noticed that a sensor they had me unplug from the factory housing (pictured below)
didn't have anywhere obvious to plug into on the new intake.
I called them and they said it's a temperature sensor, and to just connect it to a premade hole in the piping. So I connected it the only way it made sense and now the Check Engine Light is coming on.
Am I plugging it in wrong? Is there something else going on here?
