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.
