Help on installation and harness help

[1lowmonte]

I went to my local car audio shop today and i was just goin to buy the dash trim kit for my cd player, and i got that, and then they told me i needed the wiring harness. Incase i wanted to sell my car and put back the old stereo. I bought it, do i really need it? They said, its almost needed anyways, becuase you plug teh box thing into the old harness of the factory stereo. Also, teh dash kit, didnt come with any extra pieces, just from screws and thats it. No brackets. Help me out.

Thanks,

Also, i asked the guy, which i thought was the owner, if i needed any kind of GM adapter, which i thought was needed for any old cars when puttin an aftermarket stereo in. He said i didnt? Is this right?
Is the harness, really necessary?

No its not needed but it makes life easier in the long run trust me.<-Harness
The adapter may be needed all it is is an extention for your FM antenna wire. You can get them at radioshack for $2. The harness you can get at walmart or radioshack for $9. The dash kit is like $15.
