Glad to hear about your dimmer!
Dale sent me this link to wire diagrams. This should let you know what any wire is in your Jeep. They are pretty easy to read, but then again...I also work on multi-million dollar aircraft as an electrician. To check for shorts (what you call "ground leaks") use a multimeter and switch it to ohms and stick one lead to the chasis(ground) and the other to bare wire or pins. If you get zero (or close to 0) ohms, you have a short. If you have 1 M or more ohms....I would say it's pretty much open or not grounded. Then again, I don't know what kind of meter you would be using (digital or analog). Hopefully this makes sense to you.
