I sent you an e-mail, sorry for the delay (been busy)
I'm also posting it here.
Good Luck with your project.
I used a small security camera, I made a template from ABS to mount the camera in,the camera lense is waterproof and is sealed to the trunk lock hole, it took some time to make the templates and get everything mounted properly, there are no modifications to the trunk lid, the key lock parts can be reinstalled at any time to put the car back stock.
In the extreme case that the trunk lock solenoid would fail, I made a tool that can access the lock mechanism by removing the
license plate light.
The only issue that I have is that unlike a mirror the images are not reversed and when looking at the monitor (because the
camera is facing backwards) cars that are passing you on the left, or I should say (since this IS an Impala SS) cars you are
show up on the monitor on the right.
I am trying to locate a small camera that will reverse the image to correct this problem.
I have my monitor and camera hooked up so that any time the car is out of park the camera automatically comes on and also
defaults from the video source to the rear camera (unless you find the hidden switch).
