The large hose is probably the positive crankcase ventilation (PCV) hose. This needs to be hooked up to the intake otherwise it will just vent into the engine compartment and emit oil vapor, making a mess over time. The other hose needs to be connected also, it's probably a dashpot. It acts as a shock absorber when you let off the gas pedal real quick. It brings the throttle slowly to idle for the last little bit of travel. The engineers that designed these cars didn't put anything on them that they didn't need. Obviously vaccumn is needed to operate whatever is at the end of the hose, I don't have the manual open in front of me. It's at home in Boise, I am in Afganistan. (isn't the internet a wonderful thing) By the same token if they put it on, I would try to connect it close to where it was on the original intake. You may have to drill a hole and install a small steel tube with some epoxy to get the hoses connected. You may want to get a small gromet and drill a hole to fit it. Some aftermarket stuff is so general that it doesn't have all of the necessary connections for all of the original hoses.
