Was there a special episode or is it just a continuing joke, as in

Hard to remember OR describe. In a 69: Hot to the horn. Return 
from the horn goes back to the steering column where it connects 
to an insulated bearing thru to the steering column itself (so yes, 
normally the column is at 12 V. The horn ring switch connects the 
column to a wire that runs down the hollow column and across the 
(insulating) flexible coupling, connecting to the steering gearbox 
shaft. The steering gearbox has a ground wire from its top to the 
frame of the car (since the front axle beam is otherwise insulated 
from the body by its rubber mounts.)

Power comes from the hot side of the coil, thru an in-line fuse 
holder, joins a 2-wire cable and runs to the reverse gear switch at 
the Rt side of the nose of the tranny. The second wire comes back 
and connects to a Tee which splits to the backup lights on each 
side.

On my 69, I have had lots of trouble with getting these to work. I 
FINALLY discovered that the problem was that the bumper WAS 
NOT GROUNDED! In spite of being securely bolted to the body 
there was NO electrical connection. Next time I get that car out I 
will heat up those bolts to break the rust free and exercise them.

Quick comment on screws, bolts, and electrical connections in 
general: For any kind of fastener exposed to weathering,  
ESPECIALLY if it gave you any kind of trouble getting it apart or 
making a good connection, put a dab of any kind of grease on it 
before you put it back together. 

I do this on anything I take apart, including turn signal lens screws 
and bulb contacts.
