The first thing you will need to do is find the power wire from the wire
harness. All you need is one of those needle test lights. Once you find
the power wire, hook it to the power inlet wire to the CD player. If CD
player does not light up, check the fuse on your disc player.
Sometimes there is an inline fuse, or a very small 10 amp fuse on the
back of the disc player. Did you have a good ground for the ground
wire? That could be your problem also. All you should need is 12 volts
to the player and a ground wire. Should light up. Then just hook up all
the other wires to speakers, antenna, etc.....
