Hello, Matthew -
You don't mention that you have the wiring diagram for the player. You can find it here:
http://shop.panasonic.com/support-only/CQ-C1300U.html
Scroll down the page to the link to the PDF CQ-C1300 Operating Manual. Left click on the link and download the manual. Note: You will need Adobe Reader (free) software to download and save the manual.
The manual includes the wiring diagram in the Electrical Connections section, starting on Page 44 (Image 8-25) of the PDF document.
