I've come to the conclusion that my car isn't prewired even tho it has the Infinity system in it. No matter where I look, I can't find the wiring behind the left side rear seat, or anywhere in the trunk.

Does anyone have any diagrams or instructions that can help me bring a wire from the head unit to the trunk, show me where and what to mount it to, and how all the connections are done. Thanks in advance.
