How to Install a Hidden OEM Dash Cam in a Ford F150 Without Cutting Wires

If you're looking for a clean and factory-style dash camera solution for your truck, a Ford F150 OEM Dash Cam is one of the best upgrades you can make. Unlike windshield-mounted cameras that leave visible cables and suction cups on the glass, an OEM-style dash cam integrates neatly behind the rearview mirror and maintains the original appearance of the vehicle.

In this guide, I'll walk you through the installation process we recently completed on a Ford F150 using a Mercylion OEM-style dash camera. The installation requires no wire cutting, no splicing, and preserves all factory functions.

Why Choose an OEM Dash Cam for Ford F150?

Many F150 owners dislike traditional dash cams because of:

• Visible power cables
• Windshield clutter
• Obstructed visibility
• Cheap aftermarket appearance
  

A hidden dash cam for Ford F150 solves these issues by integrating directly into the mirror housing area.

Installation difficulty:

⭐ Easy to Moderate

Estimated installation time:

20–30 Minutes

Step 1: Inspect the Factory Mirror Assembly

Begin by examining the rearview mirror housing and identifying the factory wiring location.

The OEM dash camera is designed to mount directly beside the mirror assembly, creating an almost invisible installation once completed.

The compact OEM camera integrates neatly into the factory mirror area.

Step 2: Remove the Mirror Housing Cover

1.Locate the mounting bracket included in the Mercylion dashcam box.

2.Use the correct screwdriver to loosen and remove the rearview mirror screw.

3.Install the bracket behind the rearview mirror.

Step 3: Mount the Dash Cam Module

Position the camera housing beside the mirror assembly.

Ensure:

• Camera lens faces forward
  
• Housing does not interfere with mirror adjustment
  

Step 4: Locate the Factory Power Connector

After install the dashcam base plate, locate the OEM connector attached to the mirror assembly. This connector supplies switched ignition power and is the connection point for the dash cam harness. One of the major advantages of a Ford F150 Plug and Play Dash Cam is that no wire cutting is required.

Step 5: Install the Mercylion Y-Split Harness and Hide the Wiring

Route excess wiring inside the mirror housing.

Disconnect the factory connector.

Connect the vehicle-specific Mercylion Y-split cable between:

• Factory connector
• Original mirror module
• Dash cam power cable
  
  

This method preserves all OEM functions while supplying power to the camera.

Why This Matters

Unlike fuse-tap installations, the Y-harness:

• Eliminates fuse box work
• Speeds up installation
• Maintains factory wiring integrity
• Reduces installation risk

The plug-and-play harness allows power sharing without modifying factory wiring.

Step 6: Connect to the Dash Cam App

Power on the vehicle.

Download the app from manual. Connect your smartphone through the built-in WiFi system.

Using the mobile app, you can:

• View live video
• Download recordings
• Change camera settings
• Format memory cards
• Enable parking mode
  
  

Final Installation Result

After installation, the camera is almost completely hidden behind the mirror area.

From outside the truck, the setup looks factory-equipped rather than aftermarket.
