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.
