You should have a wire that exits the steering column through a hole just below the dash. It will have a cover that is screwed to the column if it hasn't been removed. This is where the TS wires come out too but the horn wire is not part of the TS wires. The horn wire attaches to the insulated bushing that is in the top of the column tube and provides a ground to pick the horn relay when you push the horn button. It's the brown wire with the white shrink tubing in my picture.
