How to Install a Car Alarm in a Mitsubishi Galant

Installing an aftermarket alarm system or simply replacing an old system adds convenience features and piece of mind. Installing an alarm in the Mitsubishi Galant takes about two hours and a working knowledge of automotive electrical systems. Basic alarm systems for the Mitsubishi Galant include a shock sensor, alarm siren, LED light and a control module.

Things You'll Need

• Alarm kit with vehicle wiring adaptors
• Zip ties
• Drill
• Screwdrivers

Instructions

1. Read the alarm manufacturer's manual carefully and identify each of the parts included. Open the hood and remove the positive battery cable from the terminal. Connect the alarm power wire to the positive cable and run it along the firewall to the driver's side.

2. Find an open area in the engine bay and mount the siren facing the engine. Pull the wires to the driver's side of the firewall and feed all of the wires through the firewall and into the cabin.

3. Remove the lower dash panel beneath the steering wheel and open the fuse box. Snap the alarm's door lock module into the existing door lock relay, located above the fuse box. Drill a small hole for the LED light and snap it into place.

4. Mount the shock sensor for the Galant per the manufacturer's instructions and locate the starter wire in the ignition harness in the steering wheel column. Attach the start disable relay and run all of the wires under the dash.

5. Connect the power, LED, siren, door lock and disable relay wires to the control module. Mount the control module as far into the dash as possible by securing it to a heavy wire bundle or cross member with zip ties.

6. Reconnect the positive battery cable and test the alarm. Adjust the alarms sensitivity as needed and secure any loose wires with zip ties.

Tips & Warnings

• Installing an alarm yourself can void the factory warranty.
