The cruise control/horn problem does sound like a steering wheel wiring problem. Disconnect the battery for 10 minutes before attempting to remove the airbag, as the air bag system keeps a residual electric charge to deploy the bags even with loss of electricity. 10 minutes will be more then safe. Remove the airbag, and hopefully it will be something as simple as an unhooker connecter in the steering wheel. When I had my Ranger and changed wheels, I beleive there was 1 connecter with all the wires, so it would be great if that solved your problem. Good Luck!
