How to Install a Car Alarm in a Mazda6
- 1). Read the alarm installation manual and identify all of the parts and wires. Open the hood and disconnect the positive battery cable from the terminal. Attach the alarm's power wire to the positive cable and run it along the back of the firewall to the driver's side of the Mazda6.
- 2). Secure the siren in an open area in the engine bay. Point the siren towards the engine to limit water exposure when driving. Secure the wires along the body panels and firewall to the driver side of the engine bay. Feed all of the wires through the existing wire entry hole or drill a new hole.
- 3). Remove the bottom portion of the dash of the Mazda by removing the small panel on the bottom left corner. Pull out the screw and unsnap the clip on the right side of the dash. Secure the alarm control module as far into the dash as possible with zip ties and mount the shock sensor by following the manufacturer's instructions.
- 4). Locate the power lock relay around the fuse box and connect the alarm's power lock module. Drill a small hole in a visible location for the LED light. Snap the LED into the hole and run the wire to the driver's side of the dash.
- 5). Identify the starter wire in the ignition wire bundle behind the steering wheel. Connect the start disable relay and run the wire to the alarm control module. Connect the remaining wires to the control module.
- 6). Reconnect the positive battery cable and test the alarm. Adjust the alarm sensitivity as required and secure any loose wires with zip ties. Replace the bottom dash panel.
