If I don't plan to have anything added in the trunk other than Sirius, can I just run CANH, CANL, audio+, audio-, PWR, and GND straight from the trunk to to the dash?
I've looked at some of these custom harnesses, but I don't think it's necessary is I don't ahve CDC or phatnoise.
There are 3 audio wires (left, right, ground) but yes, that's all you need. Make the audio wires shielded to be on the safe side. An if you consider adding an iPod or so, add 3 shielded wires for the audio pass-through.
