reprogrammed pcm

I just rec'd my reprogrammed pcm from madwolf. Should I disconnect the battery to change it out for my old one or does it not matter?

I always tell people to pull the fuse or disconnect the negative battery terminal, but I never did it on my cars. Too lazy to look for the wrench I guess.
