You don't have to take anything apart to disconnect the battery, although it is an awkward reach.
What I do is to flip open the red cap on the underhood fuse block and loosen the terminal that is underneath it.
This is the positive lead, so you could theoretically short something out, but there is nothing but plastic for much farther than my wrench.
Or you could just pull the ECM fuse. There are two options:
1) Underhood Fuse Block Fuse 7 (BCM)
2) Body Control Module Fuse 25 (ECM/TCM)
