Thinking of put in a new CD player in my 92 Subaru Legacy L. Just wonder if someone can help to provide the audio wiring diagram or perhaps the colors code that will help. please help. thanks a million.

Just purchase a new interface harness that will tie between the new deck and the cars existing harness. This way you don't have to cut into the existing harness. You just make the connections between the new decks harness and the interface harness that plugs into the cars existing connection plug. You should be able to get a harness at most car audio outlets for about $15 dollars. The leads are marked and color coded. Just match them up to the new deck leads. I recommend you solder the leads and use some heatshrink over the joints .

Subaru changed the wiring harness for the 93 model year, but most Legacy's continued to use the old harness until MY95. It is easy to tell which model you have though.

 

If you have one single factory radio connector you have the new 1993+ harness (still in use today), if you have two separate wiring harnesses you have the old style one used on 89-92 Legacy's. Some earlier Legacy's did use the newer connector though, so you have to take the radio out to confirm.

 

Here are links to Crutchfield's wiring harnesses:

 

89-92 old style dual connector

 

93-current single connector

It is all well and good to obtain the adapter plugs as suggested above.  These adapters will certainly plug right into the plugs in the car.  However, you still need to know which wire goes where (in the chassis) so you can match them up with the wires coming out of the new radio!  I did a google search for the radio wiring diagram for my 1992 Legacy and found several conflicting charts and diagrams.  Seems like you need a correct diagram or, at best, your new radio won't work or, worse, you will damage it. Am I missing something?  If not, can someone direct me to a reliable wiring diagram for this?

 

Thanks!
