what do the colors mean?

when my brother installed my new radio in my 98 saturn, he for some odd
reason decided to cut the wires behind the radio...i want to sell my car
now, but i want to put the radio back in...does anybody know where i can
find a wiring diagram that will explain the wires that come out of my 98
factory saturn radio??
"unclenick"

 

Typically, this is the following scheme:

Blue = remote antenna
Red = positive (+12 V)
Black = ground (also grounded through chassis of stereo)
Orange = dim
Yellow = battery backup (+12V trickle current)

Speakers are in pairs Green and green/black wire, purple and purple/black,
white and white/black, grey and grey/black. I don't remember which is left,
front, right, or rear - you can also probably call Circuit City or someone
and they can offer you more help.

The wiring harnesses probably didn't match up, esp. if he used an
aftermarket, non saturn, radio thus making splicing necessary. Can't you
just match up the colors? You're putting a Saturn radio back in, so all
the wires should match right up.

 

Weird he didn't use a harnass adapter - they're cheap and common.

I looked in my Chilton's and found everything but the radio wiring.
Then I found my old instructions from Crutchfield. This doc is dated
4/2/98, ref doc no. 120 70-1858

Note - this is for a 1997 SL-2
