Once the spring clips or bolts are removed, you can slide the radio off of the rail. Because this rail can sometimes interfere with the chassis of a new radio, it may have to be removed too. Something to keep in mind: once this is done, you often cannot reinstall the factory radio.

If you are not using a custom wiring harness, look for a bare, unpainted bolt or screw that contacts the bare metal of your vehicle's chassis. Loosen the bolt, slip the ground wire underneath (this is almost always a black wire), then tighten the bolt. If your ground wire doesn't contact bare metal, your stereo won't operate. A loose or weak ground connection can result in signal noise interfering with your music.

Notice that battery voltage travels through a high current wire (red) through the relay to the horn and also through a smaller wire (blue) through the ignition switch to the relay's low-current coil. The first thing you should be aware of is that the horn circuit is always "hot" or "live" when the ignition switch is turned on and all that's needed is a path to ground.

Make sure it is plugged in, free to move and not burnt or melted. Many of the electrical components on your vehicle can be tested without being removed by measuring a resistance value between certain contacts. If you’re handy with an ohm meter and have a repair manual for your vehicle you can test the component that way.

As wires carry electricity they get hot, so it is possible after a lot of use for a connection to melt and no longer make contact. If the connect is outside of the cabin of the car it could get rusty or dirty to the point where electricity will no longer flow. It is also possible that from use and vibrations the wires simply disconnect. In this case you need a wiring diagram for your vehicle, a circuit tester and a lot of patience.
