Introduction
This guide provides information on the installation of the DS3/DS3+ and DS4/DS4+ modules as a digital solution. Using these modules in a
digital configuration requires the module to be flashed with vehicle-specific firmware. Refer to our website (www.directechs.com) and click
on the DIRECTLINK text in the header for additional information.
DS3/DS3+ and DS4/DS4+ modules provide an all-in-one solution for most modern vehicles, and include remote start, keyless entry, security,
and immobilizer bypass capabilities. T-harnesses may also be used in many applications for easy installation.
The following methods are available to configure modules:
• Web: www.directechs.com (DS3/DS3+ and DS4/DS4+)
• Desktop application: Directlink DT (DS3/DS3+ and DS4/DS4+)
• Mobile device: Directlink App (DS4/DS4+ only)
When flashing via Directlink DT (desktop app) or via the Web, an XKloader2 will be required.
To configure via Web or DirectLink DT (desktop app):
1. Disconnect the main module from any (+) 12V power source.
2. Connect the module to your computer using the XKLoader2.
3. Follow the steps in the pop-up window that will be displayed when the module is detected.
Notes:
•Flashing via web is only possible using Internet Explorer on Windows 8, 8.1, and 10.
•This method is not compatible with any other browser (Edge, Chrome, Firefox, etc.).
•When using Windows 11 or newer, Directlink DT is mandatory.
The DS4/DS4+ module is designed to be configured using the DirectLink application through mobile devices.
To download the DirectLink mobile application, visit the Google Play or Apple store. They can also be
configured via Web and DirectLink DT. The DS4/DS4+ features are built in Bluetooth® 4.0, allowing you to
configure and control your system. The DS3/DS3+ module is not equipped with Bluetooth®, therefore is not
compatible with the DirectLink app for mobile devices.
To configure via DirectLink mobile app (Android/iOS):
1. Follow and complete the wiring diagram(s) related to your installation through the app.
2. When installation is complete, select Configure DS4/DS4+.
3. Follow the on-screen instructions.

Firmware notes
IMPORTANT: This firmware does not include functionality to disarm the vehicle's OEM alarm system. The OEM Alarm Inhibit option
is set by default when flashing your module. To ensure vehicle security, we strongly recommend the installation of a hybrid system that
combines a remote starter and alarm.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
Fuses: It is important to check that the fuses are positioned correctly in the module. Proper fuse positioning is displayed on each wiring
diagram.
Refer to the "Vehicle connections" following the installation diagram.
Conditions and Limitations
Remote Start: All doors must be closed and locked to remote start the vehicle.
Power Windows Data feature: Depending on the vehicle's trim level, the Power Windows Data feature may not be supported
during remote start runtime.
Takeover: OEM Remotes or Smart Handles must be used to unlock the vehicle for proper vehicle takeover.
Note: Please ensure that you print and provide the client with the "Quick Reference Guide (QRG)". The QRG contains vital
information and instructions pertaining to this matter.
Footnotes
[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory hood pin or if
not supported in data.
IMPORTANT: In vehicles not equipped with a Factory Hood Pin, you must permanently ground the vehicle's N.C. OEM Hood Pin
input for successful operation. See the 'Vehicle Connections' section for hood pin location.
[2] Siren: The siren is only required when enabling the security features during module flashing.

Module programming
Refer to “LED diagnostics and troubleshooting” for more information and for troubleshooting purposes.
For Convenience-Only and Security-Only programming, see next sections.
1Ensure vehicle is in a safe location and cannot move forward during programming. For
vehicles equipped with a manual transmission, make sure the gearshift is in the neutral
position.
2
Connect the 12-pin main power harness to the module.
DS3+: Wait until the LED turns ON solid red then proceed to the next step.
DS4+: The LED turns ON solid blue for 1 second to confirm Bluetooth communication. Wait
until the LED turns ON solid red, then proceed to the next step.
3Connect the remaining harnesses to the module.
4Press the brake pedal then press the Push-to-Start (PTS) button once (1) to start the vehicle.
The LED flashes green then orange slowly.
5Press the PTS button once (1) more to turn the ignition OFF.
6
Remove the module from the vehicle and reconnect it to your computer. The website
