Well... have a haynes and chilton manual for this truck and still more questions....... On the air intake housing "frying pan" there are 2 vac hoses attached on the lid....one has the egr attached and goes to to handle part of frying pan the other is not attached to anything with a nail in it..... any idea where this one would go...... didn't see anything open but they did take the factory a/c off so could it have attached to there somewhere? Thanks
