bucket seats

I want to replace the OEM seats with lightweight bucket seats however I noticed that there are some connections to be unplugged and 2 airbags in each seat

can anyone who changed theirs please let me know how to do it properly? I heard the airbags or seatbelt pretensioners might pop when removing the connections?
 
if your selling your old seats im very interested mate (i know im a vulture;-) ) they will not pop as i have changed mine before. I always unplugged the battery first though so would maybe suggest that to be safe!
 
All mine are off.. no issues bar the annoying light on dash! Just disconnect the battery for ten mins before!

Also, they dont make subframes for aftermarkets, I had to get full custom jobbies at a big cost!
