okay this is a 9-volt battery holder switch on the backside brought enough power and ground wire coming out put the battery inside slide this off here's a little grip right here so it pops right off standard nine volt battery fit inside now they do have different variations different sizes but you can see there's a little bit of gaps meant that fit too so you slide it in push it over it is flirty sensitive so make sure that you line these up correctly and the locks in place and good to go and once you're go ahead and put the cover back over [Music]
