###  **Installation Guide: GPS Tracker with Engine Immobilization**

![TR500-Lite](https://storage.crisp.chat/users/helpdesk/website/-/4/3/d/8/43d837e8d5f88000/imm-wiring_1ewhf98.png)


#### 📦 **Required Components:**
* GPS Tracker device
* 12V or 24V Relay
* 2A Fuse & fuse holder
* Engine starter wire (DO NOT connect to ignition or fuel system)
* Vehicle battery (12V or 24V)
* Cut-off switch (optional for manual override)
* Electrical tools (wire strippers, connectors, etc.)

### 🔌 **Wiring Overview:**
The GPS tracker is wired to the relay which, when activated remotely or automatically, **cuts off the engine starter motor circuit** — effectively immobilizing the vehicle.

### ⚙️ **Step-by-Step Installation Instructions:**

#### **1. Power Connections**
* 🔴 **Red Wire (Tracker Power Input):**
Connect to a **fused +12V or +24V power source** from the vehicle battery (through the fuse box).
Install the **2A fuse inline** for safety.
* ⚫ **Black Wire (Ground):**
Connect to a solid **vehicle chassis ground**.

#### **2. Ignition Detection**
* 🟠 **Orange Wire (ACC/ Ignition Detection):**
Connect to the **ACC wire** of the ignition switch.
This helps the tracker know when the vehicle is ON/OFF.

#### **3. Immobilization (Relay Connection)**
* 🟡 **Yellow Wire (Relay Trigger):**
Connect to the **relay coil's positive terminal**. This wire activates the relay to break or connect the starter motor circuit.
* ⚪ **White Wire (Engine Starter Sense):**
Connect to the **engine starter motor line** (not ignition or fuel line). This wire should go to the circuit that starts the engine motor when the key is turned to START.

#### **4. Relay Wiring (Standard 4-Pin Relay)**
* **Yellow Wire:** Connect to Yellow wire on tracker
* **White Wire:** Connect to constant power
* **Green Wire: **Connect to Starter motor

### 🟢 5. **Starter Wire Cut**
* Locate the **starter motor wire**.
* **Cut the wire**, and connect:
    * One end to Green
    * Other end Green



### 🧪 Before **Testing the System**
1. **Please call our support team on 02 7908 5453 so we configure the Tracker**

### 🧪 **Testing the System**
1. **Turn the key to ACC** — the tracker should power up.
2. **Immobilize REGO on the portal** to activate the immobilizer.
3. Try starting the car — the engine should **not crank**.
4. Deactivate the immobilizer — the engine should crank and start normally.

### ⚠️ **Important Notes:**
* DO NOT connect the immobilization to the **fuel pump** or **ignition coil**. Use only the **starter motor line**.
* Always verify relay orientation (check markings on your relay).
* Double-check connections and secure all wiring to prevent short circuits.
* If you're not experienced with vehicle electronics, consult a professional installer.
