Comments on: How to Install a Car Alarm

on 12/25/2009 Thanks for this info!

on 9/18/2008 For wiring diagrams for your specific vehicle relating to installing your new car alarm system then check out the website with it all: http://www.caraudiohelp.com/car_alarm_install_guides/car_alarm_install_guides.htm

on 5/29/2008 I bought a remote starter from autoalarmpro.com and it came all set up for my 03 sierra including a installation guide that showed exactly waht wire from the remote starter connected to what wire in my truck. The install went pretty easily. I had to call tech support for some clarification and they were a big help and very nice. I higly recommend their systems.

on 5/21/2008 hey, i install my alarm. the car alarm i have, it ave both a remote start and an alarm on it. i hooked everything up but i didnt hooked up the starter.i just wanted the alarm to work but is there a way that the alarm disarm when the car is running? the remote works to lock and unlock the doors but it arm itself about a minute after i unlock the doors. it keeps on doing that even when the car is on. is there a wire to disarm it when the car is running? or something is screw up somewhere?

on 3/29/2007 HI I PUT THE ALARM I MY HYUNDAI ELANTRA 2007 INMEDIATLY THE ELECTRICS STEERING BLOCKED AND DONOT FUNCTION THE ESTEERING .I NREMOVE THE ALARM AND PERSIST , I NEED HELP . MY EMAIL IS PUPPYMANO@AOL.COM I APRECIATE YOUR ATTENTION THANKS

on 2/25/2007 i have a question.. there is a wire hanging from the alarm through the firewall, it is red and black,(red stripe with a black stripe). the place that installed this alarm claim that wire is supposed to hang. yet the alarm keeps blowing the fuse in the fuse box. when i engage the alarm, it works until i put my lights on, and im thinking this wire is a ground of some sort? any help?

on 8/8/2006 Never probe anything in a yellow loom or wires taped with yellow electric tape. The majority of cars use this to indicate airbag wires. A voltmeter is best, but if the car is pre 1996, a test light should do fine.

Also, it's a good idea to loom all your alarm wires, or use electric tape to tape it all up. The tape will make it much harder for a thief, but it can also make it hard if you ever have to service it.

You can also get tricky and tape some of your wires (maybe your power wires) with yellow tape or loom, and make it look like airbag wires!

Always remember; an alarm is only as good as its installer.

on 8/8/2006 Parts: 1. diode 2.normally close relays.
Step 1. Connect the positive of the diode to the positive wire of the siren.
Step 2. Tap the orange alarm wire, which is then connected to pin 85 of 1st relay, pin 86 of the relay is connected to the negative of the diode. Pin 30 is connected with a constant 12 volt, pin 87 is connected to pin 86 of the 2nd relay.
Step 3. Locate the black/white domelight output of the alarm and connect it to pin 85 of the 2nd relay.
Step 4. Pin 30 of the 2nd relay is connected to a constant 12 volt and pin 87 is connected to the positive of the car horn. Only when the alarm is triggered will the car horn honk.

on 6/30/2006 If you live in a lower crime area and just want people to stay away from your stereo, light your car up. Put a few LEDs in visible spots. Hook your lights or parking lights up. Most novice thieves will avoid LEDs. Most amateur thieves will avoid flashing lights.

on 6/30/2006 The first thing a professional thief will do is pop the hood. If he sees a siren or a wire loom that looks out of place, he will cut the wires and your alarm is done. Hide those wires, hide that siren, make him think for a second. Make it so he has to pull the cable off the positive terminal to make the thing shut off.

Keep your alarm going for as long as possible. A backup battery and a 2 way paging system may help if you live in a higher crime area.

on 6/30/2006 Car alarms have many fancy detectors. If this is your first time installing a car alarm you will realize it's a very tedious process. Just do the basics. Find your door switch wire (only a positive or a negative detection wire is required), and install the shock sensor. If you want a glass breakage sensor or a radar sensor, wait till later. Just get started and see if you can tough it out.

on 6/30/2006 If you are new to installing car alarms, you probably have noticed there is no specific manual to installing them for your car. Location is critical. Out of sight, yet not out of sound, shock or view. The easiest place for me to start was directly behind the battery and beyond.
The main unit goes greatly in most cars behind the glove box. Most factory installers put it on the drivers side. Running wires to the drivers side is quite easy and not too pricey. The trick is to keep the system on (especially if you have a paging system) and to think like a criminal (how is it possible to break into my own car).
Keep your sensors in locations that define what your sensor will detect. For example, Shock sensor. Mount it directly on a piece of metal inside the car. Don't even use double sided stick tape. Duct tape that bad boy on plastic to metal. You can always lower the sensitivity (or put some thick tape on) afterward if it goes off when you start your lawn mower.

The previous owner of my car had a factory guy do it, he put the shock sensor on the plastic steering wheel shaft and got his car stolen. Now that I've installed it, it does what it's supposed to do. Punch any part of the metal and it will trigger.

The glass breakage sensor would logically need to be located around glass that would break. Any small windows in the car, preferably on the drivers side, would be best. It detects a certain frequency.

Use your own judgment, you can do it. There is no reason to pay $100 an hour to have a foreign system installed in your car when you can do it yourself for free and gain knowledge and experience.

on 11/22/2005 To teach the system, turn the key on and off for about three times until you hear a chirp or beep, then try arming and disarming.

on 11/22/2005 On vehicles with airbags, ALWAYS use a voltmeter to test wires. NEVER use a test light! The current draw from a test light is enough to trigger the airbags if you probe the wrong wire.
