Precautions & Safety
OPERATION. Use of the 2310B outside its intended purpose as described in
this Instruction Manual, could result in damage to the vehicle or surround-
ing property, or cause serious injury or even death. As the installer of this
security system, it is your responsibility to ensure that the vehicle owner is
properly informed of all the details of your installation which are pertinent
to safety.
SAFETY POINTS TO ABIDE BY:
Never start the vehicle’s engine in enclosed spaces that lack adequate1.
ventilation. Extended exposure to carbon monoxide exhaust fumes
can result in death!
Do not disconnect the vehicle’s battery, as it could cause serious prob-2.
lems with modern airbag systems, anti-theft radios and/or vehicle di-
agnostics. Resulting problems could be so severe that you would need
to have the vehicle serviced, at your expense, by your vehicle dealer.
If you ignore this warning and choose disconnect the vehicle’s battery
anyway, rst disconnect the main power wiring harness of the 2310B
and then disconnect the vehicle’s battery.
Do not proceed with installing this system in vehicles that do not3.
have a 24-volt electrical system. This system will not function prop-
erly in 12-volt vehicles, and any damage resulting from such installa-
tion shall be the sole responsibility of the installer.
Do not install the 2310B control module or associated sensors in or4.
near water, or in a location where water could gather. The 2310
control module and accessories are not waterproof, and an electrical
short could occur if water gets inside. Only the siren can safely be
installed in the engine compartment.
Do not install the 2310B control module in an environment of intense5.
condensing humidity or steam, in an area with an unusually large
number of airborne particles, or any place where oil could build up
inside the control module case. All of these extreme environments
could lead to an electrical short and possible cause a re.
Avoid installing the 2310B and its associated sensors near sources6.
of intense RF transmissions which could possibly interfere with the
operation of the system. If you nd the system is randomly working
and not working, consider relocating the antenna wire and sensors.

INSTALLATION
Installation Tips
Steps Toward a Professional Installation:
•Secure all electrical contacts so you cannot easily break the connection
by tugging on the wires. Use solder if required, and securely cover all
connections with electrical tape, heat shrink tubing and/or corrugated
tubing.
•Use only a DMM (digital multi-meter) to test leads or take voltage read-
ings. Do not use “test lights” or “logic probes” (“computer-safe test
lights” included) because they draw a large amount of electrical current
that could overload and destroy sensitive circuitry in the vehicle.
•Manually turn off all lights (such as the dome light) that trigger when
a hatch is opened so you will not run down the battery. If you cannot
manually turn off all the lights, then remove the appropriate fuses and
don’t forget to replace the fuses after your installation is complete.
•Remember to not lock the keys in the car during your installation!
Leave a door open or roll down a window, just in case.
•Consult the vehicle owner about where the Status LED, Control Module,
Siren, and Sensors should be mounted.
•If you cannot nd a suitable constant +24 volt power source under the
dash, run a thick-gauge wire direct to the battery terminal. Do not dis-
connect the battery, but rather connect to the battery terminal clamps
by removing the appropriate bolts.
•When running extension wires (such as a +24v lead to the battery),
use a wire gauge that is at least as big or bigger than the wire you are
extending.
Recommended Tools and Accessories:
•DMM (digital multi-meter)
•Battery-powered drill & driver
•Electrical Tape or Heat Shrink Tubing
•Soldering Iron & Solder
•Corrugate Tubing
•Wire Stripper/Crimper

The 2310 can easily interfaced with vehicles that have (–) negative “Type-B”
door locking systems, in most cases without any optional parts. Most Asian
made vehicles use this (–) door lock scheme.
TYPE-B Vehicles that use a (–) negative door lock scheme have 3 wires at
the master door lock switch. Probe the 3 wires and you should nd one con-
stant (–) 0v ground wire, and the other two wires will show (–) ground only
when the switch is pressed. See Fig-4 on the next page for connections.
IMPORTANT: The 2310 does not support door locking on vehicles that
use vacuum pump door locks or vehicles that require 2 pulses for unlock.
See “Type-E” on page 12.
NOTE: Vehicles with door lock systems other than (–) B-Type will
require purchase of optional parts such as relays and/or motors, as is
explained in the following pages.

OTHER VEHICLE DOOR LOCK SCHEMES:
TYPE-A Most American made vehicles use (+) Positive control “Type A”
door locks. Type-A vehicles have 3 wires at the master door lock switch.
Probe the 3 wires and you should nd one constant (+)12v wire, and the
other two wires will show (+)12v only when the switch is pressed. The 2310
can interface with Type-A only with the use of a pair of optional VISION

IMPORTANT TEST! Type-C systems are very similar to Type-A. Mix-
ing up the two types could damage the vehicle. To test, cut the wire that
shows (+)24v when you press the Lock switch. Next, press the Unlock
switch and see if all the doors unlocked. If all the doors unlocked, you
can safely proceed with a Type-A installation. If the doors did not un-
lock, you either cut a motor wire or you have a Type-C system.
TYPE-C Like Type-A locking systems, Type-C lock and unlock wires typi-
cally show (+)24v when you press the door lock switch. However, Type-C
systems lack factory relays, and power is sent directly from the switch to
the door lock motors . Pushing the lock switch reverses the electrical polar-
ity on the door lock motors according to the switch you pressed—so the po-
larity on the motor for Lock is opposite the polarity on the motor for Unlock.
When neither switch is pressed, the lock and unlock wires typically rest at
(–) ground. The 2310 can interface with Type-C only with the use of a pair of
optional VISION 792H-1C-24 relays. See Fig-6 below for connections.

TYPE-D All vehicles without power door locking and vehicles without door
lock motors are Type-D. The 2310 can interface with Type-D only with the
use of a pair of optional VISION 792H-1C-24 relays and the purchase of op-
tional VISION 316-24 door lock motors. See Fig-7 below for connections.
TYPE-E Vehicles which have vacuum pump locking systems are not sup-
ported by the 2310 at this time.
TYPE-F Vehicles that use a single wire to control door locking are Type-F.
Typically, doors lock by open-circuiting the control wire and unlock by
grounding the control wire. However, some Type-F vehicles do the exact
opposite — ground the control wire to Lock and open-circuit the control
wire to Unlock. Yet other Type-F vehicles use (+)24v instead of ground.
The 2310 can interface with Type-F only with the use of a pair of optional
VISION 792H-1C-24 relays.
MULTIPLEX Many vehicles now use computer-controlled locking systems
that send varying pulse widths on the control wire, often in conjunction
with resistors. Also known as “multiplex” door locks, the control wire leads
from the lock switch straight to the Body Computer (BCM) or to the fuse
box. You can test for the presence of resistors (typically 250Ω to 7.5kΩ in
size) by cutting the control wire, setting your DMM to measure Ohms, and
measuring the “switch side” of the control wire between ground or (+)24v
while pressing Lock or Unlock. Multiplex door lock systems are not sup-
ported by the 2310 at this time.

This is a general purpose power output wire for +24v devices only. Never
connect +12v devices to this wire! This wire can be used to power the in-
cluded Siren (see page 9) and/or to power the Status LED (shown above).
But always keep in mind the 1-Amp rating of this wire! If you connect to
the Siren and/or LED, you should not connect this RED wire to anything
else. But if you connect the Siren to the +24v battery, then you have more
freedom to connect multiple, low-power 24v devices to this RED wire.
This is a general purpose ground that can be used to power any combina-
tion of devices up to 5-Amp. Keep in mind this is an Output, not an Input.
As such, you still must connect the two System Ground wires, as described
on page 16. DO NOT use this ground for your door locking connections!

This wire is a general purpose power output for automotive devices that
cannot run on 24v. It is commonly used to power optional devices that are
also grounded by the 2310’s GWA Output (see page 8). Take care not to
exceed the 1-Amp rating, especially when powering multiple devices.
The Status LED is used as a visual theft deterrent when the system is

This wire must be connected to the (+)24v Igni-
tion line (showing 24v when IG switch is turned
on). You must connect this wire to trigger the siren
when the ignition goes on while Armed, for Engine
Idling compatibility (pg. 32), for Manual Disarming
(pg. 37), for Feature Programming (pg. 34), and for
Transmitter Learning (pg. 39).
There are two (–) ground inputs to the 2310, both marked “02” at the wire
tips. Because both wires are connected internally, the 2310 will function
ne if you only connect one. However, the reason for having two grounds
is increased security through wire redundancy. Hence, we strongly recom-
mend you connect both wires, connecting each to a different ground source
on the vehicle. There is no meaning whatsoever to connect both wires if you
connect both to the same ground point! And keep in mind that most security
system installation problems result from a bad ground connection, so select
your ground points with care!
This wire is the main (+)24v power input to the 2310. Be sure to connect
this wire securely to a constant 24v source, but connect this wire last so the
siren doesn’t go off.
If you cannot nd a constant 24-volt source under the dash, you may need
to run a wire directly to the positive battery terminal in the engine com-
partment. If you need to extend this 24v power wire, use wire thicker than
the H2-1 wire. Do not bypass the fuse! If you blow the fuse, replace with
a 15A blade type.

NOTE: All wires in this harness are black. A number is printed in at
the tip of each wire, corresponding to the numbers mentioned below.
IMMOBILIZER HARNESS
H3 3 Points of Immobilization
H3
There are 3 pairs of wires in the H3 harness (see page 7) that lead to 3 in-
ternal 20-Amp relays inside the 2310 control module. The relays function
as “ Normally Open ” immobilizers. Normally Open means that the each
wire pair (e.g., Wire-08 and Wire-09) are normally not connected together.
But when the system is Disarmed and then the Ignition turned on, the im-
mobilizer relay switches and connects the two wires together, allowing the
engine to be started. (None of the immobilizer relays draw power until the
Ignition goes on while Disarmed.)
NORMALLY OPEN RELAY WARNING
When considering whether or not to immobilize the fuel pump and/or Ig-
nition lines, keep in mind that all immobilizer relays used in this 2310B
security system are “normally open.” This means that even if a thief kills
power to the security system, the engine still will be immobilized. Only
when the system is Disarmed and the Ignition is later turned on will the
immobilizer relays Switch Closed, allowing the engine to be started.
The potential problem is that if something undesirable were to happen
to the relays that are connected to the fuel pump and/or Ignition lines,
there is the possibility the relays could switch back to their normal state
of “open,” forcing an immediate shutdown of the engine even while the
vehicle is in motion.
The installer therefore assumes all risk of connecting to the Ignition or
Fuel Pump lines! KIRAMEK offers information on how to connect the
2310 to the Ignition or Fuel Pump lines in the event the installer abso-
lutely must connect to those points. HOWEVER, it is strongly recom-
mended for maximum safety that you choose instead to severe only the
Starter line at 3 different points (shown in Fig-12 on the next page).
This is almost as secure and makes for a much safer installation.
