![TR500BLE](https://storage.crisp.chat/users/helpdesk/website/-/4/3/d/8/43d837e8d5f88000/t500ble-immobilization_1oqbwyr.png)

### ⚠️ WARNING:
* **Only interrupt the engine starter wire.**
* **Do NOT connect to fuel pump or ignition system.**
* This setup **prevents the engine from being re-started**, but does **not kill a running engine**.

### 📦 What You’ll Need:
| Item | Description |
| ---- |
| TR500 GPS Tracker | With immobilizer capability |
| Relay (12V or 24V) | Standard 4 or 5-pin automotive relay |
| 2A Fuse & Holder | To protect power circuit |
| Vehicle battery | 12V or 24V supported |
| Electrical connectors, tools, and insulation materials | For safe installation |

### 📊 Tracker Wire Function Table:
| Pin No. | Wire Color | Function |
| ---- |
| 1 | Red | Power + (connect to battery via fuse) |
| 2 | Black | Ground (connect to chassis or battery -) |
| 3 | Orange | Ignition Detection (connect to ACC) |
| 4 | Yellow | Relay Control (connect to relay) |

## 🔌 Wiring Steps

### 🔴 1. **Power the Tracker**
* **Red Wire ** → Connect to vehicle’s +12V or +24V power through a **2A fuse**.
* **Black Wire** → Connect to a reliable **ground point** (vehicle chassis or battery negative).

### 🟠 2. **Ignition Detection**
* **Orange Wire ** → Connect to the **ACC wire** of the vehicle’s ignition switch.
    * This lets the tracker detect when the vehicle is turned ON or OFF.

### 🟡 3. **Relay Control Output**
* **Yellow Wire**.
    * This wire activates the relay when the immobilizer function is triggered.

### 🔁 4. **Relay Wiring (Standard 4-Pin Relay)**


| **Relay** | **Connect to** |
| Yellow Wire | Yellow Wire on GPS Tracker |
| White Wire | Constant Power |
| Green Wire | Starter Motor |
**Note:** The relay cuts the starter motor signal when activated, so the engine won't crank when someone tries to start it.

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


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

## 🧪 Testing Procedure:
1. Turn the key to ACC — verify the tracker powers up.
2. Start the engine normally — confirm it cranks and starts.
3. Send the **immobilize command** from the tracking app or platform.
4. Turn off the engine and try restarting — the engine should **NOT crank**.
5. Send the **unlock command** — the engine should start again.

## 📝 Notes:
* Do **NOT** wire the relay to fuel or ignition systems.
* This setup is designed to **prevent re-start**, not to **kill** a running engine.
* Always insulate and secure all connections to avoid shorts.
* Consult a professional installer if you're unsure.
