Wire harness question
So I am going to put in a new head unit, I have the wire harness for the head unit and I'm wondering, do I need the focus harness as well or can I use the harness that powers the stock radio and use butt connectors so I can utilize the new harness? This will obviously be my first time installing a deck so I just want to make sure I have the right parts before I begin. Thanks
