Wiring Information
R e v . 1/ 28/ 00
SEC-8028
Yellow ~ Main Battery Connection (+) Fuse ~ 5 Amp MAX
Connect to a constant 12-volt source. Alpine recommends this wire to be
connected directly to the battery. Do not share this power lead with any
other components or accessories. Use a 5-amp fuse in-line at the battery
lead to protect against short circuit.
Red ~ Ignition (+)
Connect to a 12-volt ignition source. When selecting the N/O starter
interrupt, it is necessary to find a “true” ignition source for the Red wire.
When selecting the N/C starter interrupt, you may use an accessory lead.
Black ~ Chassis Ground (–)
Connect directly to a metal surface that has been cleaned from any paint or
coating. This wire should be as short as possible and should not be
connected directly to the battery.
Blue ~ Siren (+) 1.5 Amp
Connect to the Blue wire of the siren. Connect the Black wire of the siren to
chassis ground. If more than one siren will be used, use a relay to drive
all of the sirens.
Orange ~ Starter Interrupt Output (+) 200mA
Connect the Orange wire of the security system to the Orange wire of the
supplied relay. Connect the Black wire of the starter interrupt relay to
chassis ground. The starter interrupt can be configured as a normally open
(N/O) or normally closed (N/C) circuit.
NORMALLY CLOSED STARTER INTERRUPT–Normally Closed is
the factory default setting. This configuration will assure that the vehicle
will always start as long as the security system is disarmed, even in the
event of a security system malfunction or component failure.
NORMALLY OPEN STARTER INTERRUPT–This configuration adds
more security for the customer by not allowing the vehicle to start even if a
would-be thief finds and removes the main unit or main power connection.
Open the Main Unit. Locate the jumper labeled JP1. This is the only jumper
selection inside of the main unit. Jumper JP1 will select either normally
open or normally closed starter kill relay operation. The factory default is
normally closed, or in the “OFF” position. To select normally open starter
disable, place jumper JP1 to the “ON” position. When using this feature, it
is important that the Red (ignition) wire be connected to a “true” ignition
source-12 volts through the “On” and “Start” cycles. This feature must be
enabled. See the Jumper Selection section for more details.
Yellow/Red ~ Extension LED Output (+) 20mA
Connect to the Yellow/Red of the extension LED. Connect the Black wire of
the extension LED to chassis ground. Up to 4 additional LEDs can be added
in series with the original LED. Do Not Parallel LEDs. The correct mounting
hole size is 15/64".
Red/White ~ Valet/Disarm Switch Input (–)
Connect the Red/White wire to the Red/White wire of the Valet/Disarm
switch. Connect the Black wire of the Valet/Disarm switch to chassis ground.
Brown/White ~ Door Switch Input (+ or –)
Determine the vehicle’s door pin polarity. Refer to the Programming section
if positive door input is required. Connect the Brown/White wire to the
vehicle’s door pin wire.
Green/White ~ Hood /Trunk Wire (–)
Connect the Green/White wire to the vehicle’s hood pin and/or trunk pin
wire. If both hood and trunk pin are connected to this input, you must diode
isolate each wire.
Yellow/Green ~ EXT-1 Output {(–) 1-Second or Latched} 200mA
Connect the Yellow/Green wire to control an optional accessory when the
EXT-1/Valet button is pressed and released. Some examples might include
devices such as a remote starter or window roll-up modules. Refer to the
accessory’s owner’s manual for installation instructions.
Yellow/Black ~ EXT-2 Output {(–) 1-Second or Latched} 200mA
Connect the Yellow/Black wire to control an optional accessory when the
EXT-2/EXT-3 button is pressed and released. Some examples might include
devices such as window roll-up modules or a trunk actuator. Refer to the
accessory’s owner’s manual for installation instructions.
Yellow/Brown ~ EXT-3 Output {(–) Continuous or 1-Second} 200mA
Connect the Yellow/Brown wire to control an optional accessory when the
EXT-2/EXT-3 button is pressed and held for more than 2 seconds. Some
examples might include devices such as a trunk actuator or a garage door
opener. Refer to the accessory’s owner’s manual for installation instructions.
Blue/White ~ Arming Output (–) 200mA
Connect the Blue/White wire to control an optional accessory that will be
controlled when the security system is armed. Some examples might
include devices such as window roll-up modules or additional optional
sensors. Refer to the accessory’s owner’s manual for installation instructions.
Blue/Green ~ Digital Pager Data Output
The Blue/Green wire is only for use with the optional SEC-8205 Multi-
Channel Digital Paging System. Connect the Blue/Green wire to the
Blue/Green wire of the optional SEC-8205 Multi-Channel Digital Paging
System. Do not use this wire with a conventional vehicle paging system.
Blue/Yellow ~ Dome Light Surv. Output (+ or –) 10 Amp MAX
NEGATIVE TYPE- Connect the Blue/Yellow wire to pin 85 of a
standard Bosch type automotive relay. Connect a fused 12-volt source to
pin 86. Connect chassis ground to pin 87. Finally, connect the vehicle’s
dome light wire to pin 30 of the relay.
POSITIVE TYPE- Connect the Blue/Yellow wire to pin 85 on a stan-
dard Bosch type automotive relay. Connect a fused 12-volt source to pin 86 and
pin 87. Finally, connect the vehicle’s dome light wire to pin 30 of the relay.
Yellow/White & White ~ Parking Light Flash Input (+ or –) 10 Amp MAX
Determine the correct polarity of the parking light circuit for the vehicle.
Connect the Yellow/White wire to a constant 12V+ source or to chassis
ground, depending upon the vehicle. Connect the White wire to the vehicle’s
parking light wire.
Black/White ~ Ignition/Impact Disable Input (–)
Connect the Black/White wire to the optional remote starter module’s nega-
tive output while engaged. (AKA-the sensor inhibit or sensor interrupt wire)
On-Board Door Lock/Unlock Relays (15 Amp MAX)
The SEC-8028 includes two on-board relays for locking and unlocking the
door lock system, without the need for external relays. The relays are switched
internally when the security system is either armed or disarmed. For wiring
diagrams, call Alpine FastFax and order document number 20030.
White/Blue ~ Priority Unlock Output (–) 200mA
If the Priority Unlock feature is selected, the SEC-8028 door unlock wires
(White/Green and Green/Blue) should be connected directly to the driver’s
door unlock motor wires as reverse polarity. This will unlock the driver’s door
upon disarm. The White/Blue wire should then be connected to the door
unlock wire for the type of door lock system that the vehicle requires. The
remaining doors will unlock when the TX button is pressed a second time
within five seconds after disarm. Some vehicles with factory keyless entry
may have the necessary wiring available at the keyless entry module. This
feature must be enabled. See the Feature Programming section for more de-
tails. Additional relays may be required for this feature. For wiring diagrams,
call Alpine FastFax and order document number 20040. Use only the un-
lock portion of these diagrams for the White/Blue wire.
