Trying to replace my reversing camera has turned into a real nightmare. I had to use an inspection camera to even spot it the cable connector. There is no way it could come out through the 20mm hole. appears the only way to access is by removing the rear flashing. have got this far by removing a couple of screws and lots of sika flex but have got stuck here. looks like there may be a hidden screw behind the high level brake light. Think I may have to cut the as I can't see me prising that off without breaking it. Anyone ever done this on a Burstner TD 690G? Any help would be appreciated.
