Identify electrics

Hi all - was trying to find a mobile towbar electrics fitter, but have had a look, and it seems like they may already been done. Apologies for the ignorance, but can someone confirm for me from these pics (and if so, what type they are)
And how can I tell if they have been enabled to work with parking sensors etc?
Sorry - these look like very ignorant questions!

Do they look like trailer sockets to you ?

They do - but I wasn't sure if they came preinstalled but without wiring. I agree that seems unlikely, but i thought it was worth checking
Is this what is know as 7pin twin electrics?
Thanks

Plug a trailer in and try it

I don't have one. I want to use it for a bike rack, but don't want to buy the rack until I have confirmed the electrics.

Yes twin electrics more than likely been used to tow a caravan
