Firmware notes
Aftermarket alarm: When armed, the aftermarket alarm (if available) will sound, if the trunk is opened, by using the OEM passive
entry request button near the trunk. To avoid this, open the trunk using the OEM fob button, aftermarket transmitter or SmartStart
application. Alternatively, you can disarm the aftermarket alarm before opening the trunk.
T-Harness (THNISS3D):
•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 optional Plug & Play THNISS3D T-Harness is sold separately.
•The OBDII Diagnostic Connector features will remain the same even when the T-Harness is installed.
•All T-Harness wires not listed in the diagram are not required for the installation.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
Refer to the "Vehicle connections" following the installation diagram.
Footnotes
[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory
hood pin, or if not supported in data.
[2] Tach: The tach wire is an optional connection required on some remote starters, which do not support a tach signal in D2D.
