After installing my system over the winter, I figured creating a drawing to go along with the pics of others may help other folks understand the stereo layout and where the splices fit in. Of course there is the TechInfo schematic going around and I found it perfect, I just wanted to add a little more detail. The drawing shows the factory non-JBL set up and also 2 different system set-ups; 1, adding amps, subwoofer and new door speakers and 2, adding just a woofer. Drawing 1 is based on mine, didn't do anything with the dash squawkers. I'll update this as I think of more.
Also check out this drawing from the forum and TechInfo.. http://priuschat.com/attachments/img015-5-pdf.34381/ ... Which came from this thread... the wire layout for the headunit in a 2011 prius two | PriusChat It may not be an exact match to the new model but these should at least steer you in the right direction.
