I bought a 94 z28 without the stereo, I try to install a new one, I bought all the wires nessessary but it would not turn on, seems there is no power from the battery. I check the fuse inside the car and its fine, is there any other fuse or relay that it may not be working?

 

Pick up a chilton book for your car. It will have the wireing diagram in it. The wires are all color coded so once you know what wires are what youll be able to trace them and see what may be wrong. they may have the diagrams at nastyz28.com
