For those without air bags, there is no clock spring.
Since alarm and horn does not work, it could be a fault with the horn units or its wiring.
Attached is a horn wiring circuit.
Remove the horn relay and use a jumper across the Light Green and Light Green/White terminals, if horn come on, the horn units are good. Ensure you have battery voltage at the Light Green wire.
At steering column wire harness, Use a tst lamp to ground the Light Green/Black wire and if horn come on, the problem lies with the horn switch and contact between the steering and column.
To test, an ohmmeter for testing continuity is required.
