Relays. I don't remember which is which but up near the front of the car are the relays that switch power for the A/C, foglights, and obviously some other things. I don't have my wiring harness handy but it would identify each one.

Ha sorry, I'll see what I can find. What series car, TII or N/A, 5 speed or auto? I'm guessing S4 because of the color but depending on the other criteria those relays could control any of the following according to the 1988 Factory Wiring Diagram:

-Dimmer switch
-Headlights
-Air conditioning
-Electric fan (TII only)
-Auto trans (auto only)
-Power steering

It doesn't look like any of them control the horn, but then again I've found the Wiring Diagram to be wrong on several occasions.

I think the horn is controlled by the CPU.
