Kn1z 19a361 A
Part number KN1Z-19A361-A is a genuine Ford OEM Vehicle Security System (VSS) module and perimeter anti-theft upgrade kit engineered specifically for modern Ford vehicles, including the Ford Ranger, Ford Explorer, Ford Expedition, and Ford Bronco. Designed as an authentic Motorcraft / Ford Accessories electronic module, this plug-and-play component upgrades factory keyless entry systems to provide two-stage perimeter impact shock detection, audible horn chirp anti-theft alarms, and cellular-connected smartphone remote start functionality when paired with the optional FordPass Connect cellular telematics modem.
Electronic Architecture and Perimeter Shock Detection
The engineering architecture of the Ford KN1Z-19A361-A module interfaces directly with the vehicle high-speed Controller Area Network (CAN-Bus) gateway. The module features an internal, precision piezoelectric accelerometer shock sensor capable of detecting multi-axis physical impact, glass breakage vibration, and unauthorized vehicle tampering.
The module operates on a two-stage perimeter detection algorithm. A light physical impact—such as a basketball bouncing off the fender or heavy nearby truck vibrations—triggers a warning 'warn-away' stage, sounding brief horn chirps to deter potential thieves. A heavy, violent physical impact—such as someone shattering a window or attempting to pry open a door—triggers the full emergency panic alarm: sounding continuous horn blasts, flashing exterior LED exterior lights, and sending an instant push-notification security alert to the owner smartphone via the FordPass mobile application.

Vehicle Compatibility and Factory Upgrades
The KN1Z-19A361-A module is designed for a broad spectrum of modern fourth-generation and fifth-generation Ford truck and SUV platforms. It is the primary factory accessory security module for the Ford Ranger (2019–2023), Ford Explorer (2020–2024), Ford Bronco (2021+), Ford Expedition (2018–2024), and Lincoln Aviator/Navigator platforms.
On many base XL and XLT vehicle trims that rolled off the assembly line with basic factory remote keyless entry, this module acts as the missing physical hardware bridge required to activate perimeter alarms and remote start. Once plugged in and activated, drivers can use their existing factory three-button key fobs to trigger remote start by pressing the Lock-Unlock-Lock button sequence, avoiding the necessity of carrying bulky aftermarket key fobs.

Plug-and-Play Installation and FORScan Programming
A major advantage of genuine Ford security modules is DIY plug-and-play installation. Installing the KN1Z-19A361-A requires zero wire tapping, cutting, or soldering. The kit includes a specialized OEM 'T-harness' that unplugs from the factory Gateway Module (GWM) located directly behind or above the OBD-II diagnostic port. You plug the T-harness into the gateway, reconnect the factory plug into the harness, zip-tie the security box securely to a solid metal structural bracket under the dashboard, and mount the sensitivity jumper wire.
The module features a small rotary potentiometer dial that allows users to adjust impact sensitivity from level 1 (least sensitive) to level 10 (most sensitive). While the perimeter alarm features operate automatically upon plug-in, activating remote start features on certain trim levels may require enabling remote start in the Body Control Module (BCM) and Instrument Panel Cluster (IPC) using Ford dealership FDRS diagnostic software or the popular DIY FORScan OBD-II diagnostic software.
How to Install Ford Security Module KN1Z-19A361-A in 5 Steps
Follow these five mechanical steps to install and tune the Ford perimeter security module in your vehicle.
Disconnect Negative 12V Battery Terminal
Isolate the vehicle electrical system by disconnecting the negative battery cable with a 10mm wrench before touching CAN-Bus modules.
Locate the Gateway Module Behind the OBD-II Port
Reach under the driver-side lower dashboard to access the factory Gateway Module (GWM) harness connector.
Connect the Plug-and-Play Inline T-Harness
Unclip the factory gateway wiring plug, insert the KN1Z-19A361-A T-harness inline, and snap the locking connectors securely.
Secure Module to Rigid Steel Structural Dash Bracket
Use heavy-duty zip ties to anchor the module firmly against a solid metal dash crossbar so vibrations transmit accurately to the sensor.
Calibrate Shock Potentiometer and Test Alarm
Reconnect battery, set the sensitivity dial to position 5, lock the vehicle with the fob, and strike the B-pillar to test the alarm threshold.
