Severe duty equipment operation. In addition, such systems may themselves be damaged or their operation affected by operating your vehicle. (Citizen band [CB] transceivers, garage door openers and other transmitters whose power output is 5 watts or less will not ordinarily affect your vehicle's operation.) Because we have no control over the installation, design or manufacture of such systems, Ford cannot assume responsibility for any adverse effects or damage that may result if you use this equipment. Malfunction of aftermarket electronic equipment should be resolved by the equipment manufacturer. Aftermarket equipment installation When installing aftermarket equipment, avoid using fasteners that are too long for the application or are in an area which might damage vehicle components, including wiring, brake lines, fuel tank and lines, powertrain components, exhaust system and suspension. Also, do not make electrical connections to vehicle electrical systems not specifically designed for aftermarket equipment installations. Refer to the "Electrical and Vacuum Troubleshooting Manual" for electrical system information. Do not install any components into the Powertrain Control Module (PCM) or PCM harness. Connecting into this system may affect engine and transmission operation. As an example: connection of aftermarket electrical equipment into the brake light circuit or any other circuit which is connected to the PCM, anti-lock brake computer, air bag system or any other vehicle system which will cause vehicle malfunction. Contact during a crash with aftermarket equipment in a vehicle can result in a personal injury. 7
