Our cars and their computer systems are very delicate as far as the electrical system. All the power runs from Positive to Negative.
(as in Positive voltage is applied almost everywhere and the computers control the grounds)
Because of this it is very important to disconnect the Negative first and re-connect it last.

I remove negative first because the entire car is connected to the negative terminal via ground cables , so theoretically when you touch anything metal on your car its grounded to Negative, with that said the reason i remove negative first is that way when you remove positive you don't accidentally short positive to ground with your ratchet or something during removal. This in my opinion is the ONLY reason negative is removed first
Regardless in my opinion it does not really matter which way you disconnect it as long as you don't create a short on accident which you have a higher chance of if you don't remove negative first. , Power is flowing or it is not , someone mentioned about everything being ground switched , this is simply not true , both methods are employed as far as ground switched vs power feed switched.

Negative ground... Always disconnect the negative terminal first.
I had a hell of a time just getting the old battery out. I swear they installed the battery first then everything else when manufacturing the car. Damn fuse box just wouldn't get out of the way, not enough slack on the wire harness.
