Does anyone have a wiring diagram for the vacuum pump? I am reassembling a 2013 jku. The pump is there and used to turn on when the jeep was started. Not sure if something is wrong now or what. The pressure is not bleeding back off of the brakes.

Thanks
Ron

No. That's is the braking "fluid" system. There is an electric vacuum pump mounted up under the front bumper. I would like to know what makes it operate. there are two wires that go to the pump so one is 12v and one is ground. Mine is not turning on and the brakes will not dis-engage. So I am trying to figure out electrically what my problem is.
Thank you for your response.
