So I am replacing my ignition coil on my '01 Cherokee XJ and can't get the ****ing plug off so I can do the swap. Anyone have any diagram of it or some tips to get it off? I've already popped a piece off and I really don't wanna break it.

 

That plug can be a little tricky to take off. You need to first slide out the red tab and then squeeze the tab where the wires go into the plug. A flashlight and a small mirror will help. I also sprayed a little silicon lubricant around the edge of the plug and moved it a bit to loosen up before trying to pull it off. Be patient.
