If you are really super, super, careful it doesn't make a difference. However, to be uber safe disconnect the negative terminal first. That will prevent any sparks if your wrench should contact any part of the chassis while you're disconnecting the positve cable. The chassis is grounded when the negative cable is connected.
Is your new battery factory filled and charged or did it come with the acid in a separate bottle? If it's the -BS version read my comments in the link above. If it is factory filled and charged put your maintainer on it anyway to make sure it is fully charged before you start using it.
My new battery came from the factory precharged( it was charged on 4/20) and filled ,also I did put it on a battery charger/slow charge ( Turtle), just in case.
I removed the OEM battery( no problems) installed new battery reconnected the pigtail for my battery maintainer ( when spyder is in hibernation, for it's nap). The maintainer at first had a blinking red light, now it has a solid green light. The spyder started up, did not loose any info( mileage, trip A/B, lights, LED'S, headlights, brake, fog, directionals all work) the only thing I had to reset was the clock.
