It took me three attempts at building a housing , but im finally happy with this last try.. 1.8 " monitor wired to a back up cam (well, almost , need more wire) and an led display for reversing radar, all tested and fuctional. the pic in the monitor is actually the neighbors jeep as i pointed a spare camera out of the open door.. but im 85% or better done with this project.... and all the difficult stuff is complete.
