To be quite honest I'm not sure "exactly" what the part is for. I did however think that one of the smaller hoses maybe comes from the housing unit to the engine. The other goes to another similar place. They both however join together to this part, then are dispursed to their appropriate destinations. Those two small ends that are rusted away connect to the two small lines I was holding in my hand in one of the photos. That is where the coolant is leaking from.
I tested the leak by filling my resevoir to the required level. I left the hood open and watched for any leaks while the engine was running. Inevitably it started leaking from those ends. The resevoir empties after a week or two of driving. It's not a really bad leak, but a nuisance I'd like to get rid of. I don't know if the resevoir problem and that leak are connected, but it is quite coincidental.
First photo is basically the parts involved.

Second is where one of the small hoses connects to on the side of the throttle body.

Third is where the 2nd hoses goes. Probably to the housing.

Fourth is just an overall look.
