Prepare Van Camera Mounting Spot

What happens here

For the van, the camera will be installed above the rear doors, utilizing the third brake light's location. The presenter first removes the third brake light housing. He then marks a small notch on the bottom edge of the brake light housing, which will allow the camera's wire to pass through without drilling into the metal body of the van. The notch is carefully made to avoid interfering with the reflective material inside the brake light. He uses a drill to make small pilot holes, then carefully enlarges them to form the notch.

Goal: Create a passage for the camera wire through the third brake light housing without drilling into the van's metal.
