Where can I find a wiring diagram for a 2001 se that came with a stock
radio , its gone and all I have is 2 harnesses with many wires , getting ready to put a radio in and need to find out what wire is what , I already have the antenna adapter , so I'm good to go there. Any brand faceplate / plug someone can recommend ? since I'm going from double din to the single din now ? ? Thanks in advance , Steve

 

This link has the wiring diagram for the 02-03 bt I used it in upgrading my audio system in an 01 and found it ot be the same for the most part. I have a Bose system and don't know if this holds for non-Bose stereos.
