? Electric vacuum pump

I have a 04 3500 and on the wheel well on the passenger side between the battery and firewall there is what appears to me to be an electric vacuum pump that cycles on for a couple of seconds then shuts off for maybe 10 seconds. If anyone can please tell me what this so i know what to ask for at the dodge parts house. It has a hose that runs out the bottom and t's off and goes into the firewall between the wipers and continues over and under the drivers side battery. It does not make a difference if the engine is running or the key is just in the on position. If i unplug the electric connection it stops the cycle and does not seem to affect the engine. I unpluged it today at work and drove it home with no problems. Thanks in advance
