2001 grand caravan 3.3 While checking the front driver tire air pressure I noticed what looks like a 12" vacuum line hanging down the wheel well. I traced the hose to the bottom of the front left battery tray where it exits from a small box. Does anyone know what it is and where it goes to?

Cruise control servo? Is there a throttle cable coming out of that box under the battery?

Cruise control is working. There is nothing else coming out of that box under the battery tray.

Could it be a drain basin?
