A car alarm is an investment that essentially you gives you peace of mind when leaving your vehicle unattended. Installing one may seem daunting, but armed with information, it becomes an achievable goal. However, you will require some knowledge about wire polarity and how to access the wiring of your vehicle beforehand.
It is important to plan ahead before embarking on any task. It will help save time and help you understand what to expect. Therefore, get material on different car alarms and pick the one that you are most comfortable with. Additionally, get information on your car's wiring and their colors as well as polarities and locations.
Prepare the Car Alarm for Installation
Group the wires that you will use to connect according to the purpose they serve and clip the ones you don't require using a paper clip in order to speed things up. Identify which wires go to the kick panel on the driver's side, the ignition switch and the modules for body control.
Inspect Your Vehicle
Ensure that there are no flaws on your vehicle. For instance, if there is no indicator on the dashboard when a door is opened, then the alarm will not be triggered when that door is opened, and therefore, it will not be effective.
Additionally, consult the car manual on which tools will be required for which task. This is to avoid injury and save time. Getting the proper tools to open the paneling is as important as learning about the car's wiring from the manual as well.
Wire Your Alarm
Using the information from your car manual, take out the panels needed to access the car's wiring. Select a suitable area to mount your car alarm; preferably one that is hidden. Support the car alarm using a brace before proceeding to run the external antenna, valet switch and LED light. Wire the relays first if they are part of your car alarm unit. Having done this, take the car alarm wires you had sorted earlier by function and connect them to the car wires appropriately. It is important to check polarity first before making any wiring connections.
Proceed to install the siren, which usually has a negative and a positive wire. Ensure that both wires pass through the firewall before placing the siren on the engine bay. Ensure that there's enough room on the firewall where you connect the siren. Since most car alarm units output a positive siren, connect the car alarm to the positive wire and connect the negative wire to the ground. Replace the paneling and test the alarm.
