.So this is what you need, I found it at sonic electronix : metra 70-1857 is the part number, okay so if this is the harness that fits your vehicle, open the trunk and find the head unit, not the actual amp if it's like mine it located near the antenna you will find a steel box with plugs traceable to the amp, easy, find the plug matching your replacement and switch them, run the harness through the wiring runs should be located at the top corner or bottom corner back of the back seat accessible from the trunk, you'll have to do some tucking and bending but the harness will fit fine underneath the kick plate that covers the factory wiring channel on either side of the car. Fishing wires is never fun but worth it, YouTube search your year,make,model,stereo wiring, creative words are useful sometimes to find exactly what you need, someone did a video for whatever it is you need. Hope this helps a bit.
