2004 Mercury Monterey OE Wiring Harnesses & Stereo Adapters

These are replacements for the factory harnesses that come out of your dash already. You'll only need these if your vehicles harnesses are damaged or someone cut them and spliced them to an aftermarket radio. These are female, and not the ones you'll need to adapt to an aftermarket stereo. These are the harnesses that cone from your dash, to connect to your factory stereo, or to an aftermarket adapter, to adapt to an aftermarket stereo. They also use the generic color scheme that factory harness adapters use and if you're replacing your vehicle's factory harnesses, you need a wiring diagram that shows you what's what. 90% of people need the male equivalents of these, not female. If you're looking for the adapters that connect all 3 of your factory harnesses to an aftermarket stereo, while retaining your factory amp and sub, steering wheel controls, and rear DVD system, good luck finding that. I couldn't. I had to run new lines for the new amp and sub, which was a good idea anyways. Rear DVD has a broken screen so I can't test it yet, but I doubt it'll have audio.
