Just about done with my 'under-the-hood-makeover' and I've got a few questions that I can't seem to find the answer to

1)My charcoal canister has 2 hoses coming off it that don't go anywhere.. One's black and the other is orangeish.. Does anyone have a diagram as to where all the hoses go? I checked on my other car (which had a swap done) and they don't plug into anything either, they're just chilling there
