Car Security - Basic Connections / Outputs
The leads and connections listed
below will not apply to all alarms. Some alarm
installations will require the addition of diodes
, relays, resistors,
and/or other parts. Always read your installation manual first.
Outputs
Light Flash
Illuminated Entry
Starter Interupts
Door Locks
Horn
2nd Channel / Auxiliary
Siren
LED
Inputs
Light Flash
Light Flash (-) Output with out on board relay
(diagram)
Connect to one side of the coil of an SPTD relay with the other side
connected to (+) 12 VDC, that when energized will turn the parking
lamps on. Some vehicles will not require an additional relay, others will
require more.
Light Flash (+) Output with on board relay
Connect one lead to the lead of the parking lamps that shows (+) 12
VDC when they are on. Connect the other lead to (+) 12 VDC. Some vehicles
may require one or more additional relays.

Illuminated Entry
Illuminated Entry (-) Output Negative Door Trigger
(diagram)
Connect to terminal #85 of an SPTD relay with the other side, terminal
#86 connected to (+) 12 VDC. Connect terminal #87 to ground and terminal
#30 to the (-) door trigger.
Illuminated Entry (-) Output Positive Door Trigger
(diagram)
Connect to terminal #85 of an SPTD relay, with terminals #86 and #87
connected to (+) 12 VDC. Connect terminal #30 to the (+) door trigger.
Illuminated Entry with on board relay
Connect one lead to a vehicle door trigger and the other to ground
for negative door triggers or to (+) 12 VDC for positive door triggers.

Starter Interupts
Starter Kill (-) Output (normally closed relay)
(diagram)
Connect to terminal #85 of an SPTD relay and the anode side of a diode
if not using a pre wired socket that has one included. Connect the cathode
side of the diode and terminal #86 to an ignition (+) source. Cut and connect
the key side of the starter lead in the ignition harness to terminal #87a
and the motor side of the starter lead to terminal #30.
Starter Kill (-) Output (normally open relay)
(diagram)
Connect to terminal #85 of an SPTD relay and the anode side of a diode
if not using a pre wired socket that has one included. Connect the cathode
side of the diode and terminal #86 to an ignition (+) source. Cut and connect
the key side of the starter lead in the ignition harness to terminal #87
and the motor side of the starter lead to terminal #30.
Starter Kill with on board relay
Cut and connect the key side of the starter lead in the ignition harness
to one lead (usually specified) and the motor side of the starter lead
to the other lead.

Door Locks
Door Lock Outputs
(diagrams)
First
determine the switch type then wire accordingly.
Most of today's alarms have at least a pair of negative outputs
that will provide enough current to energize the coil of one
relay each. Some will provide
both positive and negative outputs (may require adding
diodes),
or a dip switch to select polarity.
Others may have two on board relays with leads for the normally
closed, normally open, and common terminals of each relay.
These are the most common types of door lock outputs,
but I could go on. If you are uncertain
of which type of outputs your alarm has, if any, after reading your
owner's manual, use your meter. Check for positive DC voltage first.

Horn
Horn Blow (-) Output
Connect to the lead from the horn switch that shows ground when the
switch is pressed. Some vehicles will require the use of a relay to supply
(+) 12 VDC to the horn it self. If the horn does not sound when the key
is in the off position, you will need to add at least one relay.

2nd Channel / Auxiliary
2nd Channel / Auxiliary (-) Output(s)
These negative outputs will be connected to the coil of a relay or another module to control
any number of functions of the vehichle or other components;
trunk release, garage door opener, remote start, windows up and/or down, etc.
These outputs may also be a pulsed or
latched type. Some alarm and keyless entry systems may have one or the other
or both. Check your installation manual first.

Siren
Siren (-) Output
If the alarm you are installing has this output connect it to the negative
lead of the siren. Connect the positive lead of the siren to (+) 12 VDC.
See your installation manual for more info.
Siren (+) Output
If the alarm you are installing has this output connect it to the positive
lead of the siren. Connect the negative
lead of the siren to ground. See your installation manual for more info.

LED
LEDs
Many of today's alarms have a port to plug the LED directly into them.
If yours does not, there will be a dedicated lead that has a positive or
negative output. If the output is positive, connect it to the positive
lead of the LED and connect the negative lead of the LED to ground. If
the output is negative, connect it to the negative lead of the LED and
connect the positive lead of the LED to (+) 12 VDC. Do not connect
the leads of an LED to both (+) 12 VDC and ground without a resistor.
