Dometic fridge connection brick

[Antique]

Morning all

Having lived with a niggling problem for the last few years I have decided to replace the Dometic connection brick (see pic)
Whilst replacing the wiring like for like is simple enough I am concerned regarding the thermo couple and ignition plug-in connectors. Would anyone know if they have a certain removal/installation procedure or a simple pull push fit?

Any help much appreciated
All the best

They just pull out.
