Horn blowing and service light are they related? 850 1996

96 850 turbo wagon, just completed a head job. Three days later the service light is on and the horn (center fire wall) blows eratically, even when the car is off or driving. The service light goes out in 2min or less. Are these two related and does anyone have suggestions. Currently I have disconected the horn thing and still drive. Oil & temp are fine, boost and diving seems normal.... Also I would like to aquire a vacuum diagram for my records any suggestions?
Thanks

Your service light comes on every 5,000 miles and needs to be turned of by the dealer. I keep hoping my bulb burns out one of these days. It is NOT related to your alarm.
The dashboard horn is for your alarm, and your system is armed. If you don't use a key fob, unlock the driver door twice to turn off the alarm.
