Alligator alarm connection diagram: do-it-yourself installation

Today, for many people, a car alarm is not only a security system that prevents car theft, but also a device that allows you to conveniently operate the car. An alarm system such as the Alligator has a number of additional functions (automatic engine start, opening windows, trunk, etc.), which undoubtedly please the car enthusiast and provide maximum comfort from use.

How to connect an alarm

The Alligator car alarm connection diagram provides detailed information necessary for installing a security system with your own hands. Below we present the features of connecting different wires for two types of devices - with and without automatic start.

Scheme without autostart

First, let's look at the instructions for installing the Alligator alarm system, which should be taken into account when installing such systems. Basic nuances:

The control unit must be hidden from prying eyes. Most often it is installed behind the dashboard. It is better to avoid placing it in the engine compartment due to the risk of water ingress and high temperatures.

When installing an Alligator, the siren is placed under the hood. When choosing a location, make sure that the device is protected from moisture and moving elements. If it is necessary to extend the wires, this must be done inside the car to avoid oxidation.

Limit switches are placed on all opening compartments. Any metal surface is used for fastening, except for places where moisture accumulates. The free stroke length must be at least 6 mm.
The LED can be placed anywhere without taking into account the Alligator alarm installation diagram. Most often, the dashboard or the area behind the rear view mirror is used for installation. It is important that the blinking light is visible from the outside, including to an intruder.

Valet button. When installing this key, it is important to use hidden places. In this case, the driver must have access to the product when necessary. In order not to forget the location, you can indicate it in the Alligator alarm connection diagram.

The transceiver module is placed on the windshield at the top. It has a temperature sensor, so it is advisable to avoid places near a heat source.

If necessary, the shock sensor is placed in the central part of the body, and the controller is placed on a flat surface. Plan everything in such a way that you will have access to the sensor for adjustments in the future.

Particular attention is paid to the Alligator alarm connection diagram from the position of connecting wires. The following colors are used for the bottom row:

white-brown - plus of the brake sensor (for automatic transmission) or minus of the handbrake controller (for manual transmission);
purple - “plus” door contacts;
black-green - hood connection input;
brown - “minus” door trigger;
red-white - power supply circuit of the main unit with a microprocessor from the battery with a 5 A fuse;
violet white - engine control using the oil pressure regulator and the battery discharge lamp;
gray - “negative” output of the signal channel / ignition blocking / automatic closing of windows / output for opening door locks;
white-orange - starter blocking using a relay;
white-blue - output in the connection diagram for activating the Alligator alarm.

Now let's look at how to connect the Alligator alarm to the upper connectors. The following colors are used here:

red - 12-volt input, connects directly to the battery;
pink - output for powering the circuit, connects to the output of the ignition switch, where 12V is generated;
orange - “plus” for powering the electrical circuit of accessories;
purple - starter power output or blocking;
white-pink - power output of the second electrical circuit.

Autostart circuit

The connection diagram for the Alligator alarm with auto start differs little from the option discussed above. The difference is that for automatic starting you need to install a relay or auxiliary unit near the ignition switch. To attach, you need to remove the plastic trim on the steering wheel using a screwdriver or wrench. The connection is made taking into account the diagram that comes with the package.

When connecting the lower connector, the black-green one is used to connect the engine temperature controller, and the violet-yellow one is the “positive” starter interlock wire, necessary for remote starting.

Is it worth installing the alarm yourself?

The presence of a connection diagram allows you to install the Alligator car alarm yourself. In addition, to successfully complete the task, you must have skills in installing electrical wiring, plumbing tools, perseverance and accuracy. Having minimal knowledge is usually not enough, because even experienced electricians do not always take on the task of connecting such equipment.

Pros:

minimum expenses;
understanding of all processes, ease of maintenance and repair;
the ability to create different blocking and triggering modes to increase efficiency;
Increased uptime (with careful installation).

Minuses:

installing an Alligator alarm with auto start yourself is a difficult task for beginners;
large amounts of time (even with experience);
possible loss of warranty on the car if something goes wrong.

It is not advisable to install expensive Alligator alarms with your own hands, because you need to have special tools and disassemble many elements in the cabin. If you have a new car, it is also better to entrust the installation to specialists (even if there is a connection diagram).

Tamper resistance

There is one online resource where they offer to purchase a manufactured code grabber - a device that cracks alarm codes. This device looks like a key fob, but it fits most Alligator systems. The code of one-way key fobs, as well as the code of various pagers, is emulated. The exception, supposedly, will be one of them: we are talking about a key fob with a “diode” display (S-250/275).

Screenshot of one harmless site

Any car alarm that uses the keeloq code can be hacked. Let us clarify that this statement also applies to models with a “diode” display. It would be strange if something new was used in the S-275 or S-250 - both systems are budget. Draw your own conclusion.

You can immediately find a resource offering other similar equipment. But all Alligator models will be listed there.

Another site with code grabbers

Anyone who knows how to use search will find confirmation. We wish you success.

Malfunctions

There are different types of malfunctions, but the most common ones are:

The alarm doesn't respond and nothing happens when you press the key fob. In such a situation, first of all, you urgently need to remove the alarm using the service button, then check and replace the battery. If everything is fine with the batteries, then most likely the fault is in the key fob itself, then it’s better to buy a new one (two key fobs are almost always sold in the package).
The alarm does not close the car doors. Most likely, there is a malfunction in the door lock or the alarm fuses have failed; it is better not to delay with such a problem and contact a service center.
The alarm goes off on its own from time to time. First of all, adjust the alarm sensitivity. If this does not help, then try changing the location or replacing the shock sensor; replacing it with a working sensor almost always helps.

Operating modes

The driver will have to choose one of three operating modes. The first is “panic”, which triggers an audible alert. Press the lock open/close button. Pressing again will turn off the alert. The second mode is Valet, which disables the autostart of the Alligator system, for example, during maintenance or repairs. The activation process is as follows:

turn on/off the ignition;
hold the Valet button on the key fob for 4-5 seconds;
wait for the sound signal;
Check that the activity indicator is turned off.

The third mode, as mentioned earlier, is Antihijack. Blocking the electrical circuit will prevent the thief from getting far. As soon as the system detects penetration, the engine is promptly blocked. Automatic shutdown and autostart of the Alligator system, with instructions on how to start it from the key fob, you can find out the details, allowing you to quickly intervene in the process.

Car alarms are suitable for domestic and foreign cars. It is selected taking into account the required level of protection, set of options and characteristics of the vehicle’s electrical circuit. The ergonomic keychain of the Alligator system and its instructions allow you to quickly understand the functionality. Depending on the modification, the control panel is equipped with an LED screen that displays the operating parameters of the power unit. The systems are purchased and installed at an authorized center. You can perform the adjustment yourself, based on actual operating conditions.
