Hello where can I get a factory radio wire harness for my 2003 nissan 350z base I cut the wrong wires so I don't have any tail lights and I need it fixed

 

Hi Mike why don't you just solder the wires back together?
Also not sure how the radio wires can affect your tail lights

 

As he said... Just solder or crimp the wires back together man, easiest and cheapest way to do it. Here's a video on how to solder since that's the more correct way to do it, you can buy a cheap soldering iron from walmart for $5
