Hi , you need to power up your cd from the existing power up from your old stereo.if you have a plug at the rear of your old stereo..this will help you alot as all will be found at this plug...most cd,s have a diagram on the stereo back for correct hook up....if you dont know where to find your power up..send a wire from the rear of your fuse box..solder your power up to an acccesory feed at the back of your fuse box..on the power side of the fuse connecter.there are many auxilary points to connect to behid all fuse boxes...

you can use a test light to see where your power is coming from..at the rear of the fuse box..1/you want to find power from a constant source for your memory..2/and then you want power from a source which is hot only in the accesory/ignition on position, for your normal on power wire to the cd..3/and you will also need to groung one wire for earth, from the cd...4/speaker wire hook up is easy if you read the stereo pinout diagram...on the back of the unit....just dont hook anything around the wrong way..if you read carefully you will surprise yourself and have a working cd installed in around a half hour....good luck..

so i need to hook up three wires to the fuse box? thanks for the help

if you have a haynes book the diagram is in the back

 

once you find out which color wire is what, you will connect the speakers with a comon ground. the left side will share a ground, and same for the right.

 

on the cd player you would combine the front and rear grouns to the ground for that side of the car, or you can leave one ground wire on both sides disconnected on the cd player end

 

 

the individual green wire is hot all the time for the memory circuit

I think most new style stereo systems require the speaker leads to be isolated from ground. The older style cars like yours tied one of the speaker leads to chassis ground to make the connection to the sound system. I think you will need to remove the ground from the speaker and run a new wire to the stereo unit. The left and right sides can share a common lead but it is isolated from chassis ground. The newer amp designs use a balanced output and so the leads are isolated from ground.
