Problems after having a battery installed!

[Big Daddy Rubicon]

For the guys with a newer TJ. If you install a new battery or have your old one out. But then you reinstall it and your engine runs rough or other things may not be working. Check your PCM plugs which are located right above the battery! There are 4 of them on most and it is easy to bump them to were they looked plug, but are not. I have learned this the hard way myself, just a little FYI.
