i just got a kenwood kdc222 from a friend. i dont have any experience with installing these but i thought id check it out myself first. when i took out the stock unit from my 97 sunfire i saw that the alot of the wires from my car were different than the ones on the new head unit. any advice?

 

They do make harness to go from your factory harness to after market and the wires will mactch pretty much by colour.
