Proper way to disconnect battery?

What's the smartest way to disconnect the battery on a C6.
both terminals? which one first...
Just the Red?
I've never been that good with electronics..
Any advice would be appreciated, I know these Vettes can be electrically temperaMENTAL!

I'm going to be under the hood checking O2 wires, spark plugs and wires, and cleaning ....
should I even worry about unplugging the car?

I'm not a vehicle electronics expert either but I have never heard of a suggested method of removing the positive or negative terminal in some order to diconnect the battery, and I've worked on mine quite a bit without any adverse problems. But, maybe I'm missing something...

Which terminal do I disconnect first?

You ALWAYS disconnect the ground wire first, and re-connect the ground wire last. Notice how I used the term "ground" rather than "negative". Because in a positive ground system, in that case you disconnect the positive "ground" wire first.

Thanks, guys.
I knew there was a particular way, in the event I do decide to unhook the batt.

As noted always the ground (In the Corvette this is the "-" or black) terminal first and if disconnecting both terminal also connect it last.
