They could be for anything matey to be honest. Has your car got rear parking sensors fitted?? If not then these or one of them could be for that maybe?? or they could be for diagnostics but they don't look like a diagnostics port to me. Oh, Cd auto changer maybe if you have not got that too.i added some foam padding in the rear end of car as it was vibrating
the panels were just under rear window/windshield, in front of trunk and behind bass speaker
i found these connectors that are not going anywhere
any idea what these are?
