I have the vehicle listed above S, with auto climate and no Harmon speakers. I’m trying to tap into the wires in the back of the stock radio for a LOC to put an amp in my car. I could really use a diagram of the stock radio wire harness. Thanks!

Sure, here is the radio wiring diagrams and additional info for the install:

Connect the LOC: Once you've identified the speaker wires, you can use a line output converter (LOC) to tap into the audio signal.
