Last season, the Toffees suffered capital punishment at the hands of city rivals Liverpool in a 2-1 semi-final defeat - a memory Howard and his team-mates would like to banish.
"The way Wembley makes me feel, makes the team feel and makes the fans feel gives you drive to get back there," he said.
"It's always tough to lose to Liverpool in those circumstances on the big occasion so getting over it's never easy.
"You kind of puff your chest out when you know you're going to go to Wembley - everyone gets excited, the ticket requests all come in and people are singing the songs.
"So it's important but for us to get to it we've got to take care of Wigan.
"The draw's been favourable, we got a home draw finally, so that's good."
