Check the fuses. 2. Check for voltage to the horns at the horn connector. Push the horn button or jump the wire to ground to actuate the relay. If you have voltage the horns should be operable, so search elsewhere for the problem. 3. Check for voltage at the horn button. While there, check to be sure the button's contacts touch each other when pushed. If everything's ok, go to the relay. 4. With someone pushing the horn button, check for voltage (on the low-current wire coming from the dash) on the relay. If there is voltage, the relay isn't working, right?

Relays are extremely useful for handling high-amperage electrical accessories like large electric fans, fuel pumps, and HID headlights. They are activated by an electric coil and controlled by a switch. When the relay is closed, no power goes to the accessory in question. When you flip the accessory switch, an electric coil in the relay opens, sending power to the accessory.

Fusible Links, another kind of fuse, are used in many cars and are almost always found in the wiring harness in the engine compartment. These are molded, single-purpose links in the wire which are designed to melt under extreme conditions (usually a crash which might crush wires together, causing a huge short circuit). Your car's schematic will show their use and location.

The high-current wire from the battery might go through an appropriate fuse on the fuse panel or there might be an in-line fuse near the horns (it depends upon the production engineering decisions as to the most economical placement, but your schematic drawing will show its location).

Modern vehicles often include steering wheel controls to let you safely operate your factory audio system without taking your hands off the wheel. These functions include volume controls, track forward/back, and hands-free calling controls. In most cases, those controls won't work after replacing the factory radio. Thankfully, steering wheel control adapters help integrate these controls with many new stereos, so you can keep using these handy controls with your new stereo.

Like most seemingly complicated things, automotive electrical systems are collections of very simple assemblies. And lucky for us, there’s no secret as to how these things work. It boils down to basic technique. Do a few things right and you’re assured many trouble-free years of service.

Insert the DIN tools into the holes on either side of the unit until you hear a click. The tools serve to release the spring clips and also hook onto the sides of the stereo so that you can pull it out easily. Spread the tools apart slightly then pull the stereo out of the dash.

An electronic throttle control actuator is responsible for metering air flow into the engine which controls engine speed. A throttle control sensor located near the foot pedal supplies feedback data to the computer which activates the actuator. The throttle control system is integrated into the ABS, cruise control and traction control systems. In older vehicles throttle action was performed by a manually controlled throttle cable which is actuated by the driver's right foot.
