• How to Install Car Alarms on Older Cars

    How to install car alarms on older cars does not require a certified mechanic. Even someone not in the trade can perform a DIY install of a car alarm system. For a successful car alarm installation, follow these simple steps:

    Step 1. Read the Instruction Manual Thoroughly

    For the best results in your self-made car alarm installation, be sure to read the installation instructions thoroughly and familiarize yourself with the procedures. Make certain the alarm package contains all of the parts the kit was designed to contain. Most modern alarm systems contain features that may not be applicable to older cars. For example, many newer alarm systems, incorporate a door unlocking feature. Such systems work by using the existing power door locks originally equipped with the car. As a result, if your car did not come equipped with power door locks, this feature will be unavailable to you.

    Step 2. Determine Where the Equipment Will Be Installed

    Most alarm systems use an outdoor loudspeaker to sound the intruder alert. Others may use the horns your car already has. If a loudspeaker or siren will need to be mounted under the hood, find a location that is out of the way, will stay fairly dry and will not interfere with cables, linkages wires, etc. Most alarm systems have an electronic component that must be mounted in the passenger compartment, under the dashboard and near a fusebox or power source. For your DIY install, remember that it will probably be necessary to drill through the fire wall to run wiring from the passanger compartment to the engine compartment. And you will need clearance on both sides of the fire wall.

    Step 3. Before Making Any Connections, Disconnect the Battery

    Safety dictates that the battery be disconnected when any car alarm installation is taking place. Significant fire risk exists when working with battery current, since an accidental short will cause sparks which could result in a fire. Whether the car alarm installation is performed by a certified mechanic or a self-made, DIY install, safety should always be the top priority.
    Step 4. Secure All Connections and Avoid Leaving Wiring Exposed

    Solder all wiring connections and be sure to tape or shrink wrap any exposed areas. Be particularly careful to protect wiring passing through metal openings or under door panels, as access holes or fasteners could wear through insulation and create electrical shorts. Exposed wiring is a safety hazard, so keep all wires tucked safely away under mouldings.

    When you follow the installation instructions and take a few extra moments to secure your components and wiring, the car alarm installation on your older car will be quick, painless and best of all, inexpensive.
