2004 F150 5.4 3V 2wd SCAB Does anybody know what this cord belongs too? this is sitting on top of the engine and snaked through the AC line.

That's for 4wd trucks. Since you have 2wd, just make sure it's capped off and no vacuum is leaking. You can tuck it out of the way if you want, just be careful. It attaches to the backside of the intake manifold. If it pops off, not only will you have a vacuum leak, but it's a major pain to get it reconnected.
