Radio wire color

[XJ]

Hi guys, it's the first time I post in the chevy section as I'm always in the jeep post section... Anyways, I'm installing a CD charger in the car of one of my friend (Lumina Euro 3.1). As most of you could be mecanics with the mods we made, I'm sure that someone will be abble to tell me:

How can I find the ACC and the 12V wires in the back of a Delco radio... I have no volt-amp-meter for now then if you have the color of the wires or their positions I'll be soooooo happy <IMG SRC="smilies/biggrin.gif" border="0">

Thanks guys!

Do you have a test lamp???

red and yellow are usually the ones u want. red to acc and the other color to the battery for memory of stations and clock etc... there should be four wires that have nothing to do with speakers. red/black/blue and the fouth is the yellow or sometime orange one! jiMMy

Thank you for the inputs guys...

My only problem is that all seems to be green and black back there but I have a good idea now! Thanks a lot! <IMG SRC="smilies/biggrin.gif" border="0">

Just did my '89 Jimmy today. The previous owner hacked the harness/plug off.
orange hot-key on
orange/black hot-lights on
gray (small ga) hot-lights on
black ground
yellow (small ga) hot-constant
tan & yellow/white L Fr speaker
green & light green R Fr speaker
blue & light blue L Rr speaker
brown & grey/black R Rr speaker

It's easy enough to check with a test light.
