How Does GCH Backup Camera Integrate Into Third Brake Light of 2021 Chevy Silverado 3500

Updated 09/12/2025 | Published 05/24/2025

Question:

With the third brake light built or at least looking seamless in the spoiler on a 2021 Silverado 3500, how does this install without drilling a hole for the wire to come through the cab? Based on the mounting video for the ford, there is a bezel with the install kit that makes space for the wire to pass through. This install doesnt look like a bezel, it looks more like it wedges under the existing brake light.

Hey Gabe, I attached a picture that shows how the bracket and wire will be once the Custom Third Brake Light Camera for 8" Factory Monitor # GCH37FR you referenced will look once installed. The bracket fits under the light lens and the wire under the spoiler basically.

Hey Gabe, did the installation of the third brake light camera go smoothly with the bracket fitting under the light lens as shown in the picture? I'm asking because your experience could help others with similar setups.
