before the installation
➤Please read this entire installation guide before beginning the
installation. The installation of this remote start system
requires interfacing with many of the vehicle’s systems. Many
new vehicles use low-voltage or multiplexed systems that can
be damaged by low-resistance testing devices, such as test
lights and logic probes (computer safe test lights). Test all
circuits with a high-quality digital multi-meter before
making connections.
➤Do not disconnect the battery if the vehicle has an anti-theft-
coded radio. If equipped with an air bag, avoid disconnecting
the battery if possible. Many airbag systems will display a
diagnostic code through their warning lights after they lose
power. Disconnecting the battery requires this code to be
erased, which can require a trip to the dealer.
➤Remove the domelight fuse. This prevents accidentally
draining the battery.
➤Roll down a window to avoid being locked out of the car.
after the installation
➤Test all functions. The "Using Your System" section of the
Owner's Guide is very helpful when testing.

obtaining constant 12V
We recommend two possible sources for 12V constant: The (+)
terminal of the battery, or the constant 12V supply to the igni-
tion switch. Always install a fuse within 12 inches of this connec-
tion. If the fuse will also be powering other circuits, such as door
locks, a power window module, or a Nite-Lite®headlight control
system, fuse accordingly.
IIMMPPOORRTTAANNTT!!
Do not remove the fuse holder on the
red wire. It ensures that the control module has its own
fuse, of the proper value, regardless of how many acces-
sories are added to the main power feed.
➜
IIMMPPOORRTTAANNTT!!
Do not use a 12V test light or logic
probe (computer safe test light) to locate these wires!
All testing described in this manual assumes the use of
a digital multimeter.

6© 2005 Directed Electronics—all rights reserved
finding the starter wire
The starter wire provides 12V directly to the starter or to a relay
controlling starter. In some vehicles, it is necessary to power a
cold start circuit. A cold start circuit will test exactly like a starter
circuit, but it does not control the starter. Instead, the cold start
circuit is used to prime the fuel injection system for starting when
the vehicle is cold.
Use the following procedure to find the starter wire with your
multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the starter wire. The
steering column is an excellent place to find this wire.
Remember you do not need to
interrupt the starter at the same
point you test it. Hiding the
control module and connections is
always recommended.
4. Turn the ignition key switch to the start position. Make sure
the car is not in gear! If your meter reads (+)12V, go to the
next step. If it doesn’t, probe another wire.
5. Cut the wire you suspect of being the starter wire.
6. Attempt to start the car. If the starter engages, reconnect it
and go back to Step 3. If the starter does not turn over, you
have the right wire.
➜

finding the 12V switched wire
The ignition wire is powered when the key is in the run or start
position. This is because the ignition wire powers the ignition
system (spark plugs, coil) as well as the fuel delivery system (fuel
pump, fuel injection computer). Accessory wires lose power
when the key is in the start position to make more current avail-
able to the starter motor.
Use the following procedure to find the (+)12V ignition wire
with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being
the ignition wire. The steering
column harness or ignition switch
harness is an excellent place to find
this wire.
4. Turn the ignition key switch to the run position. If your
meter reads (+)12V, go to the next step. If it does not read
(+)12V, probe another wire.
5. Now turn the key to the start position. The meter display
should stay steady, not dropping by more than a few tenths
of a volt. If it drops close to or all the way to zero, go back to
Step 3. If it stays steady at (+)12V, you have found an igni-
tion wire.
➜

8© 2005 Directed Electronics—all rights reserved
finding the accessory wire
An accessory wire will show (+)12V when the key is in the acces-
sory and run positions. It will not show (+)12V during the
cranking cycle. There will often be more than one accessory wire
in the ignition harness. The correct accessory wire will power the
vehicle's climate control system. Some vehicles may have sepa-
rate wires for the blower motor and the air conditioning
compressor. In such cases, it will be necessary to add a relay to
power the second accessory wire.
finding the parking light wire
Most vehicles use a (+) parking light circuit. The (+) parking
light wire is often found near the light switch. In many vehicles
the light switch is built into the turn signal lever; in these vehi-
cles the parking light wire can be found in the steering column.
The same wire can often be accessed in the kick panel or running
board.
How to find a (+) parking light flash wire with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the parking light wire.
Usually, the area near the headlight/parking light switch is
an excellent area to start, as is the kick panel.
4. Turn on the parking lights. If your meter shows (+)12V, turn
off the parking lights and make sure it goes back to zero.
5. If it does return to zero, turn the parking lights back on

and, using the dash light dimmer control, turn the brightness of
the dash lights up and down. If the meter changes more than a
volt when using the dimmer, look for another wire. If it stays
relatively close to (+)12V, you have found your parking light
wire.
finding the tachometer wire
To test for a tachometer wire, a multimeter capable of testing AC
voltage must be used. The tachometer wire will show between
1V and 6V AC. In multi-coil ignition systems, the system can
learn individual coil wires. Individual coil wires in a multi-coil
ignition system will register lower amounts of AC voltage. Also,
if necessary, the system can use a fuel injector control wire for
engine speed sensing.
Common locations for a tachometer wire are the ignition coil,
instrument cluster, fuel injectors, or engine computers.
➜
nnoottee::Vehicles that use a (-) signal from the switch to the
factory relay may be interfaced directly by changing the
jumper (fuse) on the control module from the positive to
the negative position.

10 © 2005 Directed Electronics—all rights reserved
Use the following procedure to locate the tachometer wire with
your multimeter.
1. Set the multimeter to ACV or AC voltage and a range of 12V or 20V.
2. Attach the (-) probe of the meter to chassis ground.
3. Start the engine.
4. Probe the wire you suspect of being the tachometer wire with the
red probe of the meter.
5. If this is the correct wire the meter will read between 1 and 6
VAC and the voltage will vary as the engine rpm is changed.

the remote start process. This wire can be used to activate an
immobilizer bypass unit.
HH11//22VVIIOOLLEETT//WWHHIITTEEtachometer input
This input provides the control module the engine rpm data.
This wire is connected to the negative side of the ignition coil in
vehicles with conventional ignition coils. In multi-coil and high
energy ignition systems, locating a proper signal may be more
difficult. (See Finding the Wires You Need section of this guide
for finding the tachometer wire.)
HH11//33BBRROOWWNN(+) brake switch shutdown input
This wire must be connected to the vehicle’s brake light wire.
This is the wire that shows (+) 12V when the brake pedal is
depressed. The remote start will be disabled or shut down any
time the brake pedal is pressed.
Locate the factory brake wire using your meter. Find the switch
at the top of the metal arm coming off the brake pedal. There are
usually two wires connected to that switch. With your black
meter lead still in the kick panel, probe the suspected wire with
the meter. With the brake pedal at rest the meter should read
zero. While watching the tester, depress the brake pedal. The
meter should read 12V. Once you have found the correct wire
connect it to the BROWN H1/3 wire on the main harness to
this wire.

HH11//44GGRRAAYY(-) hood pin shutdown input
This wire must be connected to the hood pinswitch. This input
will disable or shut down the remote start when the hood is
opened.
Installing the hood pin switch requires drilling a ¼-inch hole in the
metal lip under the hood. Choose a location that will allow the pin
switch to be depressed when the hood is closed. The pin switch has
a spade connector on the bottom for the wire connection. Run this
wire into the passenger compartment and connect it to the
GRAY (H1/4) wire on the main harness.

The bypass toggle switch is designed to bypass the remote start
in an emergency or to disable the remote start functions
temporarily (i.e., for service on the vehicle or when parking in an
enclosed area). This switch is to be mounted in an easily acces-
sible location in the passenger compartment.
Connect the toggle switch as shown below.
HH11//55BBLLAACCKKground
Remove any paint and connect this wire to bare metal, prefer-
ably with a factory bolt rather than your own screw. (Screws tend
to either strip or loosen with time.) We recommend grounding
all your components to the same point in the vehicle.
note: More problems are attributed to poor ground con-
nections than any other cause. Take extra care to ensure
the ground is a clean metal-to-metal contact and secure.
