Air-conditioning connector on 1.5 diesel

[Crossland bassboy]

Hi. I very recently brought a very good Crossland Elite 1.5ltr automatic diesel and I would like to top up thr air-conditioning but thr adapter I used on a recent hyundai L pipe doesn't fit (r134) or even onthe H pipe, has anyone tried to re gas their air-conditioning and which adapter on the gas kit did you use. I'm reluctant to push to hard to make this kit fit on the L pipe fitting. Any help would be appreciated.

It's OK the reason I can't fit the toggle is that is for the r134 air-conditioning my Crossland is r1234yf so different attachments. My next question is the air-conditioning starts every time I start the car. How do I set the system so it only aircons when I want it to. I've tried in the comfort setting but this only displays rear window wiper onto automatic with reversing. Is there a way I can un set the air-conditioning
