I was working on my 2005 TJ, and pulled the battery out. Under the battery there were two things that caught my eye:
1. the battery plate has what appears to be a pressure switch. Is that what it is? I'm guessing it cuts power if the battery "escapes" it's tray. Is that correct?
2. under the tray, there is a box with what appears to be a vacuum line coming in, but nothing else. It's bolted to the fender. I have no idea what this is.
Can anyone ID this stuff?
