astroflex 1100 big problems

Hi All Have an Astroflex 1100 installed in a 2004 GMC Yukon. My vehicle is now stuck at the side of the road. One of the wires the insulation stripped off of it (one that was going to P5) and rubbed against the metal on the brake pedal - sparks flew and my wife turned the vehicle off as she should. However, now when we turn the ignition all we get is the horn sounding. Any suggestions for this newbie? Thanks, Brian

start removing fuses to the astro unit. this will prevent it from turning on.Ted

well, I had hoped this would work, but it did not. When I removed the 4th fuse from the bank of fuses attached to the astro, the horn quits sounding when turning the key to ignition. However, the truck does not start. I removed all 4 fuses and the truck does the same thing. Key turn to pre-ignition, I get dash lights, etc ... when you turn to ignite then I get no click, no turn, no lights on the dash, nothing. The two wires that go to P5 -- the one that was shorted to metal was the one that goes into some type of switch mechanism and back out. The other one looks like ground.
