disconnecting the battery before I install a head unit?

You don't need to disconnect the battery. It's always a good idea, but for a simple HU install, it's not all that necessary IF you know what you're doing (ie: don't cross positives and negatives). For simple plug and play harnesses I wouldn't even think twice about it, can't screw anything up that way.

if you are using a harness.. connect the car harness to the radio harness first, then plug it into the car... there is almost no chance of messing it up... but if you are even slightly scared of popping a fuse then disconnect the battery...
