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 require 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 (mobile 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 DT (mobile app):
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.

Pre-installation and application warnings
Firmware notes: This section highlights important information for this specific firmware and will assist in
pricing accordingly, as well as bringing awareness to any operational or vehicle limitations.
T-Harness
compatible THSUN2 Keys required for programming 1Keys required for operation 0
Important: Version 1.06 and higher use different input/output configurations and are NOT compatible with previous
versions of the wiring instructions. Updating an older firmware to 1.06 or higher will require wiring modifications. Damage
to the vehicle may occur if the appropriate wiring modifications are not done.
The optional Plug & Play THSUN2 T-Harness is sold separately.
Important! All T-Harness wires NOT listed in the diagram are NOT required for the installation. Loose wires such as Siren
Output and Hood Input may need to be pulled from the tapped section of the T-Harness. Refer to the “Wiring diagram with
T-Harness” for more information on connections and installation instructions.The OBDII Diagnostic Connector features will
remain the same even when the T-Harness is installed.
Key2GO is mandatory to control the immobilizer override in this firmware.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic
connector.
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.
Important! Smart door handles are NOT functional during runtime.
General notes: This section highlights important information for this specific firmware.
[1] The installation of an aftermarket hood pin is ONLY required on vehicles that are NOT equipped with a factory hood pin.
[2] The siren is ONLY required when enabling the security features during module flashing.
[3] ONLY required if the radio and autolights do not turn off after 30 seconds.
[4] For Security Only installations refer to the "Optional starter disable connection section".
