Help with 91 Yj Stereo wiring!

I recently purchased my first jeep a 91 yj, it came with no stereo but I thought I would have no use for one. Recently I decided I do want one and purchased one to install it but when I tried to begin I couldn't locate any of the wires to connect it. Could somebody help me out with the wiring?

I recently bought a 91 yj with no stereo. I have recently decided to install one and as I go in to install the stereo I purchase I cannot find any wires to connect anything to.. also there are no speakers which is no problem because I bought those too. Could somebody help me out with pictures of how their stereo is connected?
