Anyone who is having the black screen for the camera. Try pinching the silver part of the DVB-T PLUG. That silver part is the ground for the cable apparently and needs to contact the silver ring in the bumper plug. My camera showed black and I thought I was screwed until I did this. Hopefully this helps some people.
Also a pretty solid housing for 20 bucks was a Go Pro Hero Session Underwater housing. But of Dremmel and sealing work and you got a waterproof housing. Mine looks pretty rough but it works.
