i have found over the last few years that the connector/seals are a little firmer to reconnect and more so the square ones,oval and round ones are not to bad.a little bit of spit even helps or a tiny smear of dielectic grease can ease connection, oil based lubes tend to swell the seals a little.funny how the tight ones are always on sensors where you can barely get 2 fingers into them.
Nearly got the gas axe to mine!
