I need the Radio Wiring Diagram to a 2015 Ford Fusion Titanium

I'm trying to add an LOC to the factory radio wire harness to i can install subwoofers in the car. I can't find the wiring diagram anywhere.

Try your public library. They probably have Chilton Car manuals on line. You can access from home for free if you have a library card, which is also free.

A ford dealers parts department can print one out for you.
