My rear window is tinted on my 2018 Ford Fusion so I want to install a rear camera and smart rearview mirror with screen in my car. However, I will be installing the camera to the outside of the vehicle. I need to know if there's a way to pass the cable from the exterior rear camera into the car without having to drill a hole. If there isn't a way to do this then obviously I'll work on drilling the whole. I'm just trying to exhaust my options. Thank you!
