Electrical wiring ???

I currently have a portable GPS , the question is putting a ciggy lighter under the rear seat for power to use it on the bike? do i wire this directly to the battery or elsewhere. i don't want to blow anything up both are bloody expensive(bike elect and GPS)
.
I was going to do a direct hook-up to the battery but figured i would ask first
I know some of you have done it before.
