If I can get inside without the whole thing falling to pieces (those 'unwelcome surprises' :- ), I imagine I could solder a bit of T+E. I think that getting Wagos into that 'well' would be pretty marginal - but, even if I could, the pedantic amongst us might say that they were not, strictly speaking, 'enclosed', mightn't they? [ and I guess it would have to be 3 Wago's, since the CPC of the T+E would have to be 'parked' somewhere]You could try connecting the flex. If that fails, is the well deep enough for you to run t&e and connect using a couple of wagos?
