Here is the Hardwire Parking Kit install with pics on my '21 Prime. One note is the rear camera dose not have usb connection on side, so this is why i installed on the trim instead of widow as it will push the camera further down on rear window. I connected the constant power to red wire of dome light and the acc switch power to the green wire on lane departure sensor connector . Make a small notch at the center edge of the trim where the wire for camera will pop out. This way the trim will not pinch the wiring. Also make sure all the blue clips are on the trim and not on the car body. Just remove them from the body and slide back in onto the trim. Pull the rubber piece off first then squeeze the 2 clips on each side to pull the white plastic out. After you route the wires through, put the black rubber conduit back onto the white plastic before install it back in. *MAKE SURE YOU ROUTE THE WIRE UNDER THE AIRBAG AND UNDER THE BLACK WIRE HARNESS AT THE TOP BEFORE RUNNING THE WIRE ALONG THE TOP TO THE DOME LIGHT OPENING. Install the ACC wire to the Green wire of the sensor connector. Install the constant 12v to the red wire and the black ground to white/black stripe of the Dome light connector. Installed the rear camera base into the trim with 2 blind rivets ( I tried the 3M tape but it won't stick as you all know)
