Warning! Safety first
The following safety warnings must be observed at all times:
• Due to the complexity of this system, installation of this product must only be performed by an authorized Directed dealer.
• When properly installed, this system can start the vehicle via a command signal from the remote control. Therefore, never
operate the system in an area that does not have adequate ventilation.
The following precautions are the sole responsibility of the user; however, authorized Directed dealers should:
• Never use a test light or logic probe when installing this unit. Always use a multimeter.
• Never operate the system in an enclosed or partially enclosed area without ventilation (such as a garage).
• When parking in an enclosed or partially enclosed area or when having the vehicle serviced, the remote start system must
be disabled using the installed toggle switch. It is the user’s sole responsibility to properly handle and keep out of reach from
children all remote controls to assure that the system does not unintentionally remote start the vehicle.
• USER MUST INSTALL A CARBON MONOXIDE DETECTOR IN OR ABOUT THE LIVING AREA ADJACENT TO THE VEHICLE.
ALL DOORS LEADING FROM ADJACENT LIVING AREAS TO THE ENCLOSED OR PARTIALLY ENCLOSED VEHICLE
STORAGE AREA MUST REMAIN CLOSED AT ALL TIMES.
Use of this product in a manner contrary to its intended mode of operation may result in property damage, personal injury, or
death. Except when performing the Safety Check outlined in this installation guide, (1) Never remotely start the vehicle with
the vehicle in gear, and (2) Never remotely start the vehicle with the keys in the ignition. The user is responsible for having the
neutral safety feature of the vehicle periodically checked, wherein the vehicle must not remotely start while the car is in gear.
This testing should be performed by an authorized Directed dealer in accordance with the Safety Check outlined in this product
installation guide. If the vehicle starts in gear, cease remote start operation immediately and consult with the user to fix the problem
immediately.
OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN GEAR IS CONTRARY TO ITS INTENDED MODE OF
OPERATION. OPERATING THE REMOTE START SYSTEM UNDER THESE CONDITIONS MAY RESULT IN PROPERTY DAMAGE
OR PERSONAL INJURY. IMMEDIATELY CEASE THE USE OF THE UNIT AND REPAIR OR DISCONNECT THE INSTALLED REMOTE
START MODULE. DIRECTED WILL NOT BE HELD RESPONSIBLE OR PAY FOR INSTALLATION OR REINSTALLATION COSTS.
Remote starters for manual transmission pose significant risks if not properly installed and operated. When testing to ensure the
installation is working properly, only remote start the vehicle in neutral gear, on a flat surface and with a functional, fully engaged
parking brake. Do not allow anyone to stand in front of or behind the vehicle.
This product should not be installed in any convertible vehicles, soft or hard top with a manual transmission. Installation in such
vehicles may pose certain risk.

Introduction
The GM9 firmware for DS4+ is compatible with specific Buick, Cadillac, Chevrolet and GMC vehicles.
It is a complete solution for remote start, security (when security features are enabled), bypass, and features
built in Bluetooth 4.0 allowing you to configure and control your system. This guide provides information
on the installation of the module as an analog unit, however a digital solution could be available for your
vehicle. Please refer to the DirectLink application or www.directechs.com for more information about which
configuration is best for your application.
Warning! This module is designed to be configured using the DirectLink application for mobile devices, however it can also
be configured using the web tool located at www.directechs.com. To download the DirectLink mobile application, please visit the
Google Play or Apple store.

Key2GO
This feature is mandatory to control the immobilizer override in this firmware.
Key2GO has been designed and developed to bypass the advanced encryption layers found in modern vehicles. It uses an array
of servers to generate a duplicate of the original key, allowing the installation of a remote starter without having to give up a key.
The advantage is that this feature allows you to use one original key and the server to configure the bypass in the vehicle.
All Key2GO-compatible firmware are clearly indicated in the function list of each vehicle search result page and will also appear
on the flash page. Any first-time user must re-register to gain access to Key2GO, and some additional information will be required
to complete the registration process, such as your Directed account number and store name.
Key2GO is compatible with XKLoader2 and the online web tool, as well as XKLoader3 and the Directechs Mobile application.
Refer to "Module programming" on page 19 of this guide for instructions on how to program features using Key2GO.
Configuring the system
Important!
Once the DS4+ module is installed in the vehicle following the instructions in "Warning! Safety first" on page 3, launch the
DirectLink application on your mobile device, and select Configure DS4/DS4+. Follow the on-screen instructions to configure the
system.
Note: Your system can also be configured using XKLoader2 on www.directechs.com.
Vehicles equipped with a manual transmission
Additional connections may be required if these functions are not supported by the firmware.
Connection Description
(-) E-Brake Status Input
(Black/White, pin 17)
Must be connected to a working emergency brake in the vehicle. Although most vehicles have simple
(-) trigger emergency brake circuits note some vehicles do not and may require unique integration
methodologies.
(-) Door Trigger Input
(Green, pin 20) OR
(+) Door Input (Violet, pin
13)
Must be connected to a working door trigger in the vehicle, which monitors all doors. The unit must monitor
the door pins to allow the Ready Mode process to be enabled.
Note: Some vehicles may require unique integration methodologies for this circuit. For more information, refer
to www.directechs.com.
(AC) Tachometer Input
(Violet/White, pin 22)
Must be connected to a working tachometer signal in the vehicle (fuel injector, ignition coil, true tach, etc.)
and learned successfully to the DS4+.
RF Systems
An RF System consists of one or multiple remotes, a Control Center (antenna), and an antenna cable – various combinations exist.
An RF System allows the vehicle owner to control the system with enhanced range. Two-way models are available. Please follow
the instructions included with the kit for appropriate installation and programming information.
8504D Combo Sensor
The 8504D Combo Sensor must be paired to the device before it can be used. To enter pairing, turn the vehicle ignition to the
ON position, then press and hold the programming button on the Control Center (antenna) until the LED starts flashing. Once
pairing mode has been entered, your Combo Sensor is ready to use.
Your Combo Sensor is preset for the majority of applications, however it can be adjusted using the DirectLink application, as well

as a compatible LED or LCD remote. Please refer to the instructions included with your sensor for more information on how to make
adjustments.
When used in conjunction with SmartStart
To enable D2D communication between the DS4+ and the SmartStart one of the following actions must be executed:
• SmartStart with Loops – The brown loop must be cut.
• SmartStart with Pigtails – The gray wire must be connected to a ground source.
Loops Pigtails
DO NOT connect the SmartStart 2-pin power harness when using the DS4+. Power and ground will be provided by the D2D
connector on main module. Refer to the SmartStart documentation for further details.
D2D port configuration
The system will automatically configure the D2D ports based on your selections in the module programming. The white D2D port is
reserved for SmartStart. To ensure proper functionality with SmartStart, it is important that it is selected in the system programming
of the DirectLink application or via the online web tool.
Note: Both black D2D ports are reserved for the Control Center (antenna) and 8504D Combo Sensor.
