What have I broken? No horn & no flashers.

Hello, I would really appreciate any help with the following.
Recently I removed and then reinstalled the steering column in my 68 Plymouth Valiant, it is a column shift auto. I have obviously broken something. Now my horn does not work, one of my friends seems to think that this may be an earth issue. Also my turn signal indicators do not work. And to make things even more confusing my emergency flashers were not working. I swapped out the flasher relay and now the emergency flashers work but I still don't have any turn signals!!
