Did a couple of things:
-Changed the oil to Mobil 1 HM 10w30 Synthetic and a Mobil 1 Extended Performance Filter. Runs excellent now, hopefully it'll work better than the VR1 oil I had in it before, which doesn't last very long in the 4.0 from my experience.
-Added a hidden power outlet behind the glove box. I made a little bracket to bolt it to an existing bolt on the body, screwed the power outlet to the bracket then secured it with a small hose clamp, and then used an "add a fuse" tap to tap into the existing cigarette lighter fuse in the fuse block behind the glove box.
The reason I did this is because I run a dash cam in my TJ 24/7, mainly due to the bad driving and insurance (or lack thereof) scams in Philly. I've had one installed for about year but I had to snake the plug/wiring behind the radio and use the existing cigarette lighter outlet, which was annoying as I often knocked the plug out. Now the wiring is all hidden and eventually I'll get a rear-view mirror mount for the camera so it's hidden a bit better out of plain sight.
