I took the radio out of my 96 a couple years back and it is pretty simple. You will need to get a radio removing tool (T87P-19061-A or its equivalent but check to make sure yours takes the same as mine and if i remember i got mine at Walmart). It is a u shaped tool that is basically the "key". Put them in the holes on the four corners of the face plate of your radio. It takes a little persuasion to get it out but it will pull straight out...disconnect the wires and the antena plug in the back and that's it :D The wiring diagrams is a complex and insanely confusing outline of the electrical system of car, house, ect. It shows the connections the fuses and all that fun junk that totally gives me a headache. If you need it you can spend the extra money and buy the book for your car at an auto parts store or i think they can show you pictures of it down at auto zone but you would have to call to double check that.
