kenwood stereo in a 1996 jeep cherokee

i am looking for a complete audio wiring schematic for a 1996 jeep cherokee se.  i am installing a kenwood stereo and using the factory speakers.  I just purchased this jeep and know nothing on the history of the stereo...just that it didnt work when i bought it.

does your jeep have any markings either on the doors or pillars or the factory radio that say "infinity" on it? need to know this because that will tell me if you have the factory premium system and you will most likely need to do something completely different depending on whether or not your jeep has this equipment. you might be able to lift up the back seat on the drivers side and see the factory amp or at least the wires that go to it. if the amp is missing then that is why your speakers dont play.
