pioneer avh x7500bt, 2004 ram 1500

Hello guys.....semi newbie here with a wiring question. I have a 2004 Ram 1500 that I previously installed a single din head unit on. I then had a professional installer put in an amp and new speakers. Now I am in the process of adding a single din DVD unit and wanted to know where you guys would suggest mounting the black ground wire terminal to? It is coming off of a Pioneer AVH-X7500BT unit and I have the aftermarket brake bypass wires as well that will have to be spliced in with the black ground. Is there a spot in the dash somewhere I can screw the terminal into? If I have to remove some paint that's no big deal......just not sure where to put this wire at Thanks in advance

You can ground anywhere. You can drill a hole, take the paint off, then screw a connected to your ground wire eyelet, onto it. The factory ground wire that's already there, should be fine. If not, hook the brake bypass to a separate ground.
