ok so i decided to try to put in an aftermarket cd player in a plymouth neon i have a wiring harness to make it easier but this one also has another ground its not the braided ground but it hooks directly into the back of the factory radio i tried to hook that wire into the back of this cd player but it wont power on i know this wire is wat is causing all my troubles but i dont know wat to do about it help me if you can pictures or detailed instructions will be very helpful

 

make sure your antenna is also pluged in and check the fuse. some headunits use the antenna as a ground.

 

o i plugged that in too and ive chacked the fuse for the radio and the fuse in the cd player imma have some pros look at it prolly i got the audio cables and amp turn on wire waiting to go but the cd player is the hold up

 

If that ground has a plug, just rig up some sort of connector and attach it to any piece of metal in the dash framework. That should fix it I hope. Let us know how it turns out
