EJ. I make the assumption that the CD player is in the radio, and not a separate unit... To install a radion electrically is no big deal... You have the following wires: ground most probably black, continuous 12volts, switched 12 volts, one is yellow, the other is red. Take a voltmeter, or a 12volt bulb and measure ground vs. yellow and ground vs. red. Turn the ignition key on and of, one will loose the voltage the other will be continuously on. You have to connect the radio accordingly to those wires. Most probably red goes with red, yellow with yellow. Check the radio wires for their labels. If you mix up the continuous with the switced no big deal, later you can exchange. (it will forget the preset station, worst case it will pop the fuse) Pay attention to the ground wire, it has to be connected to the ground of the radio. In addition, you have the antenna, thick coax with a typical antenna plug, connect it to the antenna connector on the radio. You can do that at last, because the cable is typically short, and you can not work well if the radio is very close to the dash board. 8 more colored wire for the 4 speakers. The wires are for example red and red/white, green and green/white etc. They are a pair, belonging to one particular speaker. If you know the radio speaker wires (label)which one is front left, etc, you are half way there. Normally this is on the label. Now you take a AA battery, and momentary touching one pair of speaker wires. One wire to AA plus, the other to AA minus. Does not matter which goes to plus or minus. Momentary! one of your 4 speaker will make a noise. So you will know whick wire pair belongs to which speaker. So you connect the speaker wires the the radio wires. The colors go together and the stripes go together. Red goes with red, red/white goes with red/white. If the colors do not match, does not matter, the radio is not always matching with the car color convention. If the radio does not have labels, you have to turn on the radio set to eg. left front, and find the left front wirepair of the radio, with the left front wirepair of the car. If you do that be carefull not to short out the other wires of the radio. You connect the 8 wires, and voila you have a working radio. If the AA battery does not make any noise at either speakers, than you have a preamp, if you follow the wires you can find it, a small box underneat the dash, you can cut it out, the modern radios have the preamp built in, you do not need it. If you have any problem or questions write to me, gabehauer@yahoo.com. I am a EE, I know this stuff, more than happy to help. I just bought my 3rd brick, I have 1 more to go. The whole family is bricking. Good luck Gabe
