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 HONDA4 firmware for Directed Digital Solutions is compatible with specific Acura and Honda vehicles.
It is a complete solution for remote start, security (if applicable), bypass interface, and convenience. This guide
provides information on the installation of the module using HONDA4. If you would prefer using this system as
a digital solution, go to www.directechs.com and search for the make, model and year of the vehicle. This will
allow you to find the proper firmware and corresponding installation guide.
Warning! This module can only be programmed via the web tool, which can be found on www.directechs.com or using the
Directechs Mobile application for mobile devices. Features and functions will become accessible when you connect the module
using the XKLoader.
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 THHOC5 OR THHOC6 Keys required for programming 1Keys required for operation 0
The optional Plug & Play THHOC5 OR THHOC6 T-Harnesses are sold separately. See "Wiring diagram with T-Harness" to
determine which T-Harness option is compatible with your specific vehicle. [5]
The Honda Pilot, Ridgeline & 2003-2006 Acura MDX are NOT compatible with optional T-Harness THHOC5 & THHOC6.
The OBDII Diagnostic Connector features will remain the same even when the T-Harness is installed.
All connectors are displayed from the wire side (unless specified otherwise).
Refer to the "Vehicle wiring reference chart" following each installation type.
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 connection is ONLY required when enabling the security features during module flashing.
[3] The Green wire is ONLY required for starter disable and antigrind applications.
[4] If available, the vehicle High Speed F-CAN connections are ONLY required for the Automatic VIN Detection, when using
the DirectLink application and/or SmartStart advanced features.
[5] Connect this wire ONLY if the Trunk Release feature is not supported in data. See "Vehicle application guide" on page
6 for more information on supported features.
