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.

Firmware notes
IMPORTANT: Do NOT turn vehicle ignition ON with ANY vehicle connectors disconnected, including during module
programming. Failure to do so may result with errors in the instrument cluster or hidden error messages.
IMPORTANT: Modifications to the THHON9 are required. Refer to the THHON9 T-Harness modification section for proper use of
the THHON9 T-Harness for steps and connection details.
The optional Plug & Play THHON9 & THHON1 T-Harnesses are sold separately.
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.
Key2GO may be required if the interface does not program using the traditional method. Refer to the "Module programming" section
for more information.
All connectors are displayed from the wire side (unless specified otherwise).
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.
Footnotes
[1] The installation of an aftermarket hood pin is ONLY required on vehicles that are NOT equipped with a factory hood pin or NOT
supported in data.
[2] The siren is only required when enabling the security features during module flashing.
[3] The steering lock connection is ONLY required if the connector is present in the vehicle.
[4] For Security only installations, refer to the "Optional starter disable connection" section.
[5] When using an external relay, use a 1N4002 diode or larger. Directed Part No. 8616 Mini Relays must be used for this connection.
Refer to the "8616 wire and color reference" on the installation diagram.
[6] The PTS wire is mandatory in vehicles equipped with a manual transmission; otherwise it is ONLY required for Pit Stop/Idle mode
shutdown.
