    i run a 200 amp circuit breaker in place of the fuse in the line under the hood, it works great and you just trip it when your working on the system and reset it when finished.my last car i had a 5.0 mustang i had it installed right under the dash and never had a problem so you will be fine.yes it will be powered the same.
