horns

[turbo8]

No connection between horn button and horn on 82 280 Turbo Diesel.
Need help on wiring. Is there a relay? Tested the horn and it works.
Thanks for any advise. Frank

Frank,
The factory horns are electric (not air) and the horn button on the steering wheel should run the horn.

...any evidence of a Previous Owner's handiwork?

On my 1986 345 there is a relay for the horn located next to the fuse panel toward the gas pedal. You might try listening for a slight clicking noise from this area while pressing the horn button.
