vss wire on 2003 ram 1500 hemi

Looking to install a Navi system in my 2003 Ram 1500 Hemi. I need the VSS wire and reverse signal wire. I believe both are located passenger side by the firewall (engine comp). I just wanted to confirm color. I also got a 2 Ohm (dual VC in series should bring it to 4ohm at the amp) 10" Punch 2 sub that will be powered by a 5 channel Kicker ZX7005. Just wondering if the combo sounds ok (amps is rated at around 210W RMS at 4 ohm.. sub's rating is 300W). Doors will get a set of Boston A. SX series speakers. Nav is Pion Avic-N4... hopefully with the bypass mod so the wife can watch her TV and not bug me too much. Thanks for the input. Sam

Thanks!
