Battery disconnect for seats

Hey fellas jus curious I'm sure I have to but better to be safe than sorry I wanna vacuum under seats n sides next to center console n I wanna remove seats do I need to disconnect neg batt terminal before disconnecting cables under seats I'm sure I do jus double checking

 

I've heard of guys unplugging under seats with battery still connected and getting an airbag warning light come on after things were hooked back up. When I took mine out to clean I didn't disconnect battery and I had airbag warning light come on. But, I checked connections and one wasn't clicked in fully and that solved the problem.

As Ron said, better safe than sorry especially as its pretty quick to disconnect a battery. That being said, if you have an aftermarket stereo, be sure to go through and take pics of all your setting if you are happy with how things sound.

 

Thanks fellas
