Okay-I'm installing my new after market head unit the second it comes in mail tomorrow. I also have an 06 PT. I bought a Scosche DCCR03SRB / DCCR03SR Wiring Harness Interface Plug for CAN Bus Vehicles. Since I'll be using this wiring harness instead of the generic one, will I have also have to tap into another 12v source? Also, last question...since I bought this really expensive harness that is supposed to utilize the CAN bus interface, will I still have the digital data that displays the current radio station, input, etc? Hope so-that's why I spent the 80 extra bucks instead of going with the common wiring harness that would have come free with the head unit.
