Your '69 does not use that cancel ring with the brass contact. That 
contact is only used on the '71-on cars.

On the '69, the current comes in to the horn, which is "hot", and the 
wire from the horn runs to the steering shaft bearing, which is 
insulated from the steering column, where it makes the shaft "hot". A 
ground wire runs up the inside of the steering shaft where the horn 
button makes the connection between that ground wire and the steering 
shaft to complete the connection.

This is one of the most complicated and convoluted circuits in the 
car, and the most commonly misunderstood, but it's a good system that 
has the advantage that it does not have that sliding contact that 
wears out and damages the TS switch.
