87 300TD Horn Emergency!

[gorsuchmill]

I believe the alarm connection for the radio (after market) is causing the horn to go off repeatedly. The horn intermittently goes off and today has been nearly non-stop. I've been told there is a grounding clip or something that triggers the alarm if the radio is removed, and wonder if that was never adequately attached when the radio was installed. I pulled the radio and could not find such a connection. Please help with the following:

1) What specifically am I looking for?
2) If I can't find it is there an easy way to bypass it with another wire or bypass the system altogether?
3) Which fuse controls the alarm horn? I've pulled #2, #6 & #9 to no avail.

I thank you and everyone else annoyed by the incessant honking thanks you.

Why not unplug and disconnect the horn for now

That might be my course of action, though I'd prefer a long term solution.
