Introduction
The MA3 firmware for Directed Digital Solutions is compatible with specific Mazda, Scion and Toyota 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 MA3. 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.

Important! In these vehicles, the factory keyless entry module is sensitive to interference and may cease to operate without
notice. Please ensure you disconnect the (-) terminal of the battery prior to disconnecting and reconnecting the connectors at
the start-stop module below the steering wheel to avoid damage to the keyless entry module.
The optional Plug & Play THMAC1 T-Harness is sold separately.
Scion iA and Toyota Yaris Sedan are not compatible with T-Harness THMAC1
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.
No takeover feature is available. The vehicle will shut down as soon as a door is opened.
To remote start the engine, the hood, hatch, and all doors must be closed.
When installing this solution with T-Harness THMAC1 in one of the vehicles from this guide, the vehicle's OEM alarm will
no longer be functional. The installation of a hybrid system (remote starter and alarm combo) is highly recommended to
preserve vehicle security.
It is normal for the key symbol to flash during remote start runtime.
Parking lights for Mazda 3 can also be found in drivers kick. Please refer to www.directechs.com for additional information.
