The steering collum switch cluster includes the turn signals and wipers as well as the hazzard switch. The harness of wires just unplugs about 6 inches down the shaft. To get the horn button off, just pull it off, it should just snap out of the center of the wheel. As for the steering wheel puller, I never needed one to pull the wheel on either of my Trackers. I just removed the big nut in the center and then wiggled the wheel right off the shaft... I would give it a shot before going and buying a wheel puller... you might not need it...
