Witter makes his second defence after out-pointing DeMarcus Corley (USA) for the title last year and defending against Arturo Morua (Mexico) last time out in January.
The challenger does not consider Witter's style or his home advantage as a problem in his attempt to become a two-time world champion.
"I am here to get to get the job done and I'm not making any predictions," said Harris, the former WBA champion.
"I just know that come the end of the fight I will be WBC champion.
"I don't know what's going to happen when the fight starts but I'm going to do what I've got to do.
"He has an awkward style. He fights a bit like a coward, but I have faced more awkward people.
"I've got a lot of weapons and I'm going to win that belt. I'm not worried about the judging, the crowd or Witter, nothing."
The Hennessy Sports show in association with title partners GoldenPalace.com will be screened live on Sky Sports and also features the English Super-Flyweight Title fight between Robert Nelson and Andy Bell in an all-Yorkshire encounter.
Also in action is top domestic lightweight Lee Meager, who meets Hungarian Laszlo Komjathi in an international ten round contest.
