GKU D700/D900 Dash Cam Hardwire Kit User Manual

1. Introduction

This manual provides comprehensive instructions for the installation and operation of your GKU D700/D900 Dash Cam Hardwire Kit. This kit is designed to provide a continuous power supply to your dash camera, enabling features such as 24/7 parking surveillance and eliminating the need for a cigarette lighter power source. Please read this manual carefully before installation to ensure correct usage and optimal performance.

2. Product Overview

The GKU Hardwire Kit connects your dash camera directly to your vehicle's fuse box, providing a stable 5V/3A power output from a 12V-24V input. It features integrated battery drain protection to prevent your vehicle's battery from being depleted.

Key Features:

• 24/7 Parking Surveillance: Provides continuous power for parking monitoring.
• Battery Drain Protection: Automatically shuts down power when vehicle battery voltage drops below a safe threshold (11.8V +/- 0.2V) to ensure engine ignition.
• Wide Voltage Input: Compatible with 12V-24V vehicle electrical systems.
• Stable Output: Delivers a steady 5V/3A power supply to the dash cam.
• Hidden Cable Installation: Allows for a clean, integrated power solution without visible wires.
• Multiple Protections: Includes short-circuit, over-current, over-voltage, over-temperature, high-voltage surge, and input reverse connection protection.

3. Safety Information

• Always ensure the vehicle engine is off before beginning installation.
• Disconnect the negative terminal of the vehicle battery to prevent short circuits during installation.
• If you are unsure about any step, consult a professional automotive electrician.
• Ensure all connections are secure and properly insulated.
• Do not modify the hardwire kit or its components.
• Verify your dash cam uses a Type-C USB port for power. This kit is designed for Type-C connections.

4. Installation Guide

Follow these steps carefully to install the GKU Hardwire Kit in your vehicle.

Wiring Diagram Overview:

Figure 4: Simplified wiring diagram for the hardwire kit, showing connections for constant power (yellow), ignition/ACC power (red), and ground (black) to enable 24-hour parking monitoring.

• Yellow Wire: Connect to a fuse that provides constant power (always on, even when the ignition is off). This is for parking surveillance.
• Red Wire: Connect to a fuse that provides ACC power (Accessory power, turns on and off with the vehicle's ignition). This powers the dash cam when the vehicle is running.
• Black Wire: Connect to a ground point on the vehicle's chassis (e.g., a metal bolt or screw).

Detailed Installation Steps:

1. Prepare for Installation:

   Ensure the vehicle engine is off. Disconnect the negative terminal of your vehicle's battery to prevent any electrical short circuits during the installation process.

2. Mount the Dash Cam:

   Decide on a suitable location for your dash cam, typically behind the rearview mirror, ensuring it does not obstruct your view. Securely mount the dash cam.
3. Locate the Fuse Box:

   Identify your vehicle's fuse box. This is often located under the dashboard, in the glove compartment, or in the engine bay. Consult your vehicle's owner's manual if needed.

4. Identify Fuse Slots:

   Using a circuit tester, identify a fuse slot that provides constant power (always on) for the yellow wire and a fuse slot that provides ACC power (on with ignition) for the red wire. Ensure the chosen fuse slots are appropriate for the dash cam's power requirements and do not interfere with critical vehicle functions.

5. Connect the Fuse Taps:

   Insert the appropriate fuse taps (add-a-fuse) into the identified fuse slots. Insert an existing fuse into the lower slot of the add-a-fuse, and a new fuse (matching the dash cam's requirement, typically 2A-5A) into the upper slot for the hardwire kit.
6. Connect Wires:

   Connect the yellow wire of the hardwire kit to the constant power fuse tap. Connect the red wire to the ACC power fuse tap. Connect the black wire to a suitable metal ground point on the vehicle's chassis.

   

   Figure 5: Detailed diagram showing how to connect the hardwire kit to the vehicle's fuse box and ground. It illustrates the connection of the red (ACC), yellow (BATT), and black (Ground) wires.

7. Route Cables Neatly:

   Carefully route the power cord from the dash cam to the hardwire kit and then to the fuse box, tucking cables behind trim panels and headliners for a clean, hidden installation. Use cable clips or tape to secure loose wires.

   

   Figure 6: Visual guide demonstrating the steps for routing cables neatly within the vehicle's interior, including tucking wires into the headliner and A-pillar trim, and securing them to avoid obstruction.

8. Reconnect Battery and Test:

   Once all connections are secure and cables are routed, reconnect the negative terminal of your vehicle's battery. Start the vehicle to test if the dash cam powers on with the ignition. Turn off the vehicle and remove the key to verify if the dash cam switches to parking mode (if supported by your dash cam).

5. Operation

The GKU Hardwire Kit operates automatically once installed correctly.

• Vehicle On: When your vehicle's ignition is on, the hardwire kit provides continuous power to your dash cam via the ACC (red) wire, allowing it to record normally.
• Vehicle Off (Parking Mode): When your vehicle's ignition is turned off, the hardwire kit continues to supply power to your dash cam via the constant power (yellow) wire. This enables your dash cam's parking surveillance features (e.g., collision detection, time-lapse recording) for 24/7 monitoring.
• Battery Protection: The integrated low voltage protection circuit monitors your vehicle's battery voltage. If the voltage drops below 11.8V (for 12V systems) or 23.6V (for 24V systems), the kit will automatically cut power to the dash cam to prevent excessive battery drain, ensuring you can still start your vehicle.
