The Reds recorded a 36-10 win at the John Smith's stadium to climb within six points of the top eight with seven games of the season remaining.
"There are enough games left for us to challenge the eight," coach Harris is quoted as saying by club's official website.
"It's still in our hands. We've got a long way to go. There are a lot of bad habits at the club we're gradually changing into good habits. It was a good win for us and it's important we start picking up these wins.
"I didn't think the performance was fantastic. We've a lot of things to work on but to get a win here is always difficult and to score the points we did is good."
Next up for Salford is a meeting with 10th-placed Hull FC next weekend.
