I was given a Sony CDX-GT300 deck and can't seem to find a connecter that's compatible with the stock stereo wiring. I'm not very smart when it comes to car audio wiring so any help would be very appreciated. Thanks.

 

From the above sticky:

The wiring harness for 2002-2005 is 70-2003 (M)

I got mine dirt cheap off ebay.

 

Thanks. Much appreciated
