What have I done

I recently freshened up the motor in my 64 valiant I also removed everything from the engine bay to repaint it, I re-wrapped my existing harness and reinstalled it,I removed the steering column and changed some dash bezels as well. Now I have crazy electrical problems! for starters The blinker mechanism always makes a clicking sound and gets hot,I have no brake lights or rear signal lights( i do have running lights in the rear when the headlights are on).
The front directionals work fine. I checked the firewall plugs and made sure all the pins are making contact,I checked all the sockets and even changed all the bulbs to be sure that was not it.I did have the directional switch put together wrong but i fixed that.I checked the brake switch and that is still functioning but no juice making it to the rear lights.I have a feeling the non stop clicking of the blinker thingy is the key but I'm not sure?
