tion immediately and consult with the user to fix the problem immediately. After the remote start module has been installed, test the remote start module in accordance with the Safety Check outlined in this installation guide. If the vehicle starts when performing the Neutral Safety Shutdown Circuit test, the remote start unit has not been properly installed.
Installation points to remember Important: This product is designed for fuel-injected, automatic transmission vehicles only. Installing it in a standard transmission vehicle is dangerous and is con- trary to its intended use. Before beginning the installation: • Please read this entire installation guide before beginning the in- stallation.
➢ Virtual tach Virtual Tach is a new feature for Directed this year. It is the default RPM-sensing method for new remote start systems. Virtual Tach gives the installer the performance of a hardwired tach wire, with the conve- nience of voltage sensing. It is far superior to any voltage-sense feature you’ve tried before.
Component locations and finding wires For detailed information on where to locate components, and how to find the wires you need, please refer to the Direct Tech web site at www.directechs.com. Making your wiring connections Before making your connections, plan how your wires will be routed through the vehicle.

Relay for Positive (+) Disarm Wire H1/2 GREEN/WHITE FACTORY REARM This wire sends a negative pulse every time the remote start shuts down or the doors are locked. This can be used to pulse the arm wire of the vehicle’s factory anti-theft device. Use a relay to send a (-) or (+) pulse to the arm wire.
Page 16
H1/4 WHITE/BLUE (-) ACTIVATION INPUT This input comes from the factory set to 1 activation pulse. This means that it is necessary to have 1 ground pulse on the white/blue wire for the remote start to activate or to deactivate. The same holds true for the remote control activation when set to a two pulse setting it is necessary to press the button twice for the remote start to activate or deacti-...
Page 17
H1/6 BROWN (-) HORN OUTPUT This wire supplies a (-) 200 mA output that can be used to honk the vehicle horn. It outputs a single pulse when locking the doors with the remote, and two pulses when unlocking with the remote. This wire also outputs pulses for 30 seconds when Panic Mode is activated.
Page 18
H1/8 BLACK (-) chassis GROUND connection We recommend that you do not use a factory ground. Ground all your components to the same point in the vehicle, (preferably the kick panel). Scrape away any paint and use a factory bolt or make your own ground with a self-tapping screw and a star washer.
Heavy gauge relay interface The heavy gauge wires are used to energize high current circuits in the vehicle. It is crucial that these connections are made correctly so that they are capable of handling the current demands. For this reason, scotch locks, T-taps and other such connectors should not be used.
PINK/WHITE (+) PROGRAMMABLE OUTPUT FOR ACCESSORY OR IGNITION Connect this wire to the second ignition or accessory wire in the vehicle. (Selectable by using menu 2 feature 6.) Note: For vehicles that do not have a second ignition or accessory wire, this connection is not required.

Figure A Figure B Important! Always use the Vehicle Safety Check section of this guide to verify that the vehicle cannot be started in ANY drive gear and that the override switch is functioning properly. H2/2 VIOLET/WHITE TACHOMETER INPUT WIRE This input provides the module with information about the engine’s revo- lutions per minute (RPMs).
Page 23
H2/3 BROWN (+) BRAKE SWITCH SHUTDOWN WIRE 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 depressed.
Neutral safety switch interface Some vehicles do not have an electrical neutral safety switch. Instead, the ve hicle has a mechanical neutral safety switch that physically in- terrupts the starter wire and is used when the vehicle is in any drive gear.
eral Motors product or a Dodge Dakota pickup, please call Directed Electron ics Technical Support for an alternative shut-down method. Do not return the vehicle to the customer until this feature is properly installed! D2D and programmer interface The 4-pin red port is for interfacing with an XK module through D2D, or you can use it for programming with the Bitwriter®.
Programming jumpers ➢ Light flash (+)/(-) This jumper is used to determine the light flash output polarity. In the (+) position, the on-board relay is enabled and the unit will output (+)12V on the WHITE wire, H1/9. In the (-) position, the on-board relay is dis- abled.
Plug-in program switch The Program switch plugs into the blue two-pin connector. Tach learning ➢ Virtual tach To program Virtual Tach: After the install is complete, remote start the car. If the car does not start on the first attempt, let the remote start at- tempt again.
➢ To learn the tach signal 1. Start the vehicle with the key. DRW-96 HOLD 2. Within 5 seconds, press and the Pro- gram switch. 3. The LED will light constant when the tach signal is learned. 4. Release the Program switch. ➢...
Remote control learn routine The system comes with two transmitters that have been taught to the receiver. The receiver can store up to 4 different transmitter codes in memory. Use the following learn routine to add transmitters to the sys- tem.

Function Reset Features: This resets features all of the security system to the factory default settings. Note: This feature does not delete the remotes from the security system or reset the Virtual Tach setting. Virtual Tach Reset: Deletes all previously learned values for Virtual Tach, and on the next remote start sequence the unit begins virtual tach initialization.
Learn Routine will be exited if: • Ignition is turned off. • Program switch is pressed too many times. • More than 25 seconds elapses between programming steps. ➢ Remote Configuration Lock, Panic On/Panic Off Unlock, Panic Off Trunk release Remote Start timer mode car finder...
Operating settings learn routine The System Features Learn Routine dictates how the unit operates. The programmable operating settings of this unit can be changed when- ever necessary through the computer-based Learn Routine. The Program push-button switch, plugged into the blue port, is used together with a programmed transmitter to change the settings.

5 UNLOCK OUTPUT— , 2 PULSES: This will program the unlock output to one or two pulses. When the dou- ble pulse unlock feature is turned on, the BLUE (3) wire will supply two negative pulses instead of a single pulse. This makes it possible to directly interface with double pulse vehicles without any extra parts.

When programmed to the latched output the status will only stay active for 10 minutes. Both outputs activate 10 seconds after remote start. 9 ANTI-GRIND With the anti-grind On (default) the ground-when-locked output will be active during remote start operation. This activates the optional starter kill relay and prevents the customer from re-cranking the car with the key, when doing key takeover.

Important: Make sure there is adequate clearance to the front and rear of the vehicle before attempting this test. a. Make sure the hood is closed and no other shutdown circuits are active. b. Set the emergency brake. c. Turn the ignition key to the run position but do not start the en- gine.
Troubleshooting The starter cranks for six seconds but does not start. • Either the wrong ignition wire is being energized, the system’s ignition and accessory wires have been connected backwards, or the vehicle has two ignition circuits. Try activating the unit with the ignition key in the “run”...

Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank if active. Check connections. The two red heavy gauge input wires on the relay satellite should have solid connections. “T-taps”, or “scotch locks” are not recommended for any high current heavy gauge wiring.
Page 47
The vehicle will start and run only for about 10 seconds. • Is the remote start programmed for voltage sense? Try program- ming the unit for low voltage reference. If this does not work, a tach wire should be used. Check diagnostics.
