If you've connected the hose that feed into the head, that's the Positive Crankcase Ventilation hose. I think the other is the evaporative emissions purge line.

There ought to be fittings on the intake for both lines.

If there's only one fitting on the intake, buy a mini-breather filter for the PCV hose and disconnect it from the intake. Then, connect the evap line to the fitting on the intake.

Also, if you're in California, you'll need to swap back to the stock setup for your smog checks. The PCV mod is de facto illegal. :run:
