Swaping the seats in my VRS facelift for suede ones help please

So i have purchased some half leather half suede seats for my vrs facelift mk3.

i know how to fit them physically but i know i need to disconnect the battery to disconnect and connect new seat wiring.

My worry is if i disconnect the negative for 10 mins then disconnect and swap seat over and reconnect it, how will this impact the car as it is start stop ?

i know if i swap them without disconnecting it's a risk of deploying the airbags and ill get error messages even if i avoid deploying them.

Obviously the battery will remain and be reconnected not changed what can i expect ? or am i best to stump up the funds and have them fitted for me

Also will be selling of my seats when done they are in A! condition no wear but have some minor marks that will clean out on drivers seat literally 2 the size of a 5p coin

rears are as new my car has only done 40k miles , will have a set of door cards as well but no switches in them, will need these gone ASAP well soon as new ones are fitted

will only be asking £250 collected for the set, Collection from Scarborough
