Horn help

I haven't driven my Imperial for over six months and decided to take it out for a spin today. I don't remember ever trying the horn before, but when I tried it today, I got nothing. ??? I read through the FSM info and TS tree. It says to first check that the dash brake indicator light is on when you go to crank the car... the brake light (and horn) are grounded through the steering column. Well, I tried that and no brake light.

Additionally, it says my power antenna and the horn are on the same circuit...and the antenna works, so I'm guessing it's not the fuse.

SO... has anyone had their dash/steering column area open that can tell me what I'm looking for as far as the steering column ground wire?
