g ro mmets when wire s are run thro ugh ho les
in the ca r b o dy o r firewall.
4. Pro te ct and hide wires with flexible tubing o r
by wrapping with electrica l tape if po ssible.
Ideally, the wires sho uld be indistinguishable
fro m the vehicle’ s facto ry wiring.
5 . Mo unt all plastic co mpo nents away fro m
so urces o f e xtreme heat such a s the exhaust
ma nifo ld o r turbo charg er to prevent melting .
Also mo unt all co mpo nents away fro m a reas
that receive water directly.
6 . Mo unt all co mpo nents in such a way that
they do no t impa ir o r interfere with the
no rmal o peratio n o f the car’ s mo ving parts.
7 . Mo unt all co mpo ne nts and run all wires so
they canno t be easily reached fro m
underneath the vehicle.

Connector 2 (8-pin connector)
3 x ORANGE WIRES (to flash positive or
negaive parking lights), fig. 1
A. Determine if the parking lights are po sitively
o r negatively switched – Using a VO M meter,
test the wires co ming fro m the parking light
switch. Find a wire which chang es po larity
when the parking lights are turned O N:
(1) Po sitive (+ ) parking lig ht system – If a
wire g o es to + 12 VDC when the parking
lights a re turned O N, b ut do es no t sho w
any voltag e with the parking lights
turned O FF, this is the (+ ) pa rking light
wire.
(2) Neg ative (–) parking light system – If a
wire g o es to g ro und when the parking
lights a re turned O N, b ut do es no t sho w
any gro und with the pa rking lights
turned O FF, this is the (–) parking light
wire.
(3) NOTE:
a. Mo st vehicles have (+ ) parking lig ht
systems. A few (mainly Japanese)
have (-) parking light systems (the (–)
signal usually triggers a relay to send
+ 12 VDC to the parking lig hts).
b. If the vo lta ge o n the (+ ) o r (–)
pa rking lig ht wire varies when yo u
dim o r b righten the interio r lights,
then this is no t the co rrect wire.
B. Co nnect the fused O RANG E WIRE:
(1) Po sitive (+ ) parking lig ht system –
Co nnect the fused O RANG E WIRE
directly to a so urce o f unswitched
+ 1 2VDC at the fuse bo x.
(2) Neg ative (–) parking lig ht system –
Co nnect the fused O RANG E WIRE
directly to a so lid chassis g ro und.
C . C o nnect o ne o r two no n-fused O RANG E
WIREs:
(1) Sing le-wire parking light systems – Mo st
vehicles have a sing le circuit which
co ntro ls all parking lights. In this case,
co nnect b o th no n- fused O RANG E WIREs
to the (+ ) o r (–) parking light wire.
Connector 2 (8-pin connector)
RED WIRE (5A fuse, to +12VDC)
Remo ve the 5 A fuse, and co nnect this wire to
co nstant (unswitche d) so urce o f + 12 VDC.
C o nne ct directly to the vehicle’ s fuse bo x, o r to
the battery (+ ) terminal.
NOTE – Fo r quiet po wer-up, turn the ig nitio n

(1) Turn the pre-intrusion (1 st sta g e)
sensitivity to ma ximum (clo ckwise).
(2) Test the trigg er (2nd stage) sensitivity by
rapping hard o n the vehicle to simulate
an attack. (Do no t hit the windo w.)
Adjust the sensitivity by turning the
trigger a djustment po d clo ckwise (mo re
sensitive) o r co unterclo ckwise (less
sensitive).
(3) O nce trig ger sensitivity is set, test pre-
intrusio n (1st sta ge) sensitivity by lig htly
kno cking o n the vehicle to simulate
so meo ne bumping the car. Adjust the
sensitivity by turning the po d clo ckwise
(mo re sensitive) o r co unter- clo ckwise
(less sensitive).
(4 ) NO TE:
a. C hang ing trigger sensitivity also
affects pre -intrusio n sensitivity.
b. When trigg er sensitivity is set to
minimum, the sho ck senso r ca nno t
trigger the alarm (equivalent to
turning the sho ck senso r O FF).
Pre -intrusio n is also turne d O FF.
c. When sensitivity is set to maximum,
the sho ck senso r is very sensitive.
This may cause unnecessary chirps
and/ o r false alarms.
d. To prevent false alarms, the sho ck
senso r and auxilia ry senso rs will no t
trigger the alarm until 4 o r 6 0
seco nds (depending o n the remo te
used)after the alarm is armed a nd

A. Do o r Lo ck – Te st the do o r lo ck b y pressing
the lo ck a nd unlo ck butto ns. If the do o r lo ck
do e s no t respo nd, shut do wn then reco nnect
the a larm unit’ s p o wer, o r ma nua lly pe rfo rm
the do o r lo ck/ unlo ck prio rity le arn o peratio n
(see a bo ve).
B. Testing wire co nnectio ns – O ften, when trying
to trace a pro blem b etwe en a trigger input,
wiring, and the alarm brain, o ne place to
test is at the alarm brain itself. Set the VO M
fo r (+ ) o r (-), depending o n the trigger, then
pro be the appro priate wire near the alarm
brain while te sting the trig ger. Fo r instance ,
to determine why a
(-) do o r trigg er is no t wo rking, pro be and
test the BLUE WIRE o f the 6 -pin co nne cto r
near that co nnecto r. If the BLUE wire sho ws
(-) when the do o r is o pened, the n the
pro blem may be caused by the user no t
arming the alarm co rrectly, o r the alarm
brain may be defective. But if the BLUE wire
do e s no t sho w (-) when the do o r is o pe ned,
the pro blem may be a lo o se o r d efective pin
switch o r wire co nnectio n.
C . Senso r de la y times – The vario us se nso rs
have a sho rt delay fro m the time the alarm is
arme d until the senso r can be trig gered.
Therefo re, a fter arming the alarm, wa it until
after the delay pe rio d b efo re testing the
senso r to be sure that senso r is o perating
pro perly:
(1) Hardwired triggers – 4-seco nd delay.
(2) Sho ck (auxiliary senso rs) and Current
sensing – 60 seco nd de la y fo r facto ry
remo te and 4 -seco nd de la y fo r the
o ptio nal ENFO RCER remo te.
D. Trig gered zo ne recall – When the alarm is
arme d, trigg er any o ne zo ne o f the ca r. Then
disarm the alarm. The number o f flashes o n
the LED will indicates which zo ne was last
triggere d, reg ardless o f when it was trigg ered:
(1) 1 fla sh – The ignitio n was trig g ered.
(2) 2 flashes – Panic was trigg ered.
(3) 3 flashes – Sho ck o r auxiliary senso r was
triggered.
(4) 4 fla shes – A do o r was o pened.
(5) 5 flashes – The ho o d o r trunk wa s
o pe ned.
(6) 6 flashes – The current senso r was
triggered.
This memo ry display will sto p o nly after 15
seco nds o f inactivity.
TIPS FOR TESTING THE ALARM
When the adapter is po wered up fo r the first
time and if the ada pter will be wo rking with the
facto ry remo te, then it is necessary to manually
teach the adapter the co rrect do o r lo ck/ unlo ck
po larity as fo llo ws:
1 . Disa rm the a la rm
2. Fo r a succe ssful le arning, It is impo rtant to
manually lo c k the do o r lo ck switch o n the
do o r p ane l.
3 . Turn the ignitio n switch O N.
4 . Within 1 5 se co nds, turn the VEPLe switch o n
fo r 4 seco nds. The siren will chirp o nce to
co nfirm the a larm has entered the po larity
learn mo de. Then the alarm will
auto matically lea rn the arm input, disarm
input and disarm defeat input.
5 . Turn the ignitio n switch O FF and siren will
chirp twice to indicate a sucessful learning.

SOLUTION
See procedure on page 19.
Check blue or blue/white wire depending on which switch)
at brain with VOM. If ground when door or hood or trunk
open, and not when closed, then problem with wire harness
or brain. Otherwise, check switch, wire, or connection.
Connect trigger wire to under-dash courtesy lights, or
connect individual pin switches to each door.
Reduce shock sensor trigger sensitivity, and double-check all
door and hood/trunk pin switches.
Check all openings to see which is not closed properly.
Reprogram to restore chirp.
Check the connection.
Check the main brain ground, make sure good contact, and
not grounded together with siren.
Connect these two wires to separate sources of +12VDC.
Feature not available for -) parking light systems)
Wait 4 sec. hardwired triggers) or 15 sec. current sense)
after arming before testing.
SITUATION
Door locks not responding.
Under passive arming switch sensing), siren does
not chirp when the last door/hood/trunk is closed.
Not all doors trigger the alarm.
Too many false alarms.
More than one chirp when arming active mode).
Siren does not chirp.
Siren chirps or LED flashes while driving.
Siren continually emits a strange quiet sound.
Cut main power wire red wire), and alarm looses
power.
Testing of hardwired zone, or auxiliary sensor, or
current sensor does not trigger alarm.
POSSIBLE PROBLEM
Door lock/unlock polarity not learned.
Door/hood/trunk pin switch not connected, or
broken, or its height is not adjusted properly.
Door switches are isolated by diodes.
Shock sensor or door pin switches, or current
sensing.
Alarm detects open circuit, does zone bypass.
Set for chirp delete.
Yellow wire of 8-pin connector loose.
Poor main brain ground.
Fused orange wire and fused red wire
connected to the same source.
Tried to test the triggers too soon after the
alarm was armed.
