Technical Hot Rod Steering Columns Turn Signal Questions

Folks,
I have a Ford Model A type steering column in this 34 Plymouth Hot Rod. It has an aftermarket turn signal set up. I am trying to figure the wires out. So far, using a continuity test I have determined that the wiring seems to be:
Red-Right turn signal
Yellow-Left turn signal
Brown-Column light center
Green-Hazard lights (out)
Orange-Column power
There are two more wires, Blue and Black. Anyone familiar with this know what they are for: Horn? Ground? Thanks

 

from another thread on the HAMB

 

I would guess flasher and ground.

 

Thanks Fellas, Squirrel, hey I'm in Hereford AZ....

 

I'm right down the street, near Ramsey rd

 

I try to save things like bolt on turn signal diagrams in my Photobucket album. Most of them are fairly similar as most evolved from a basic design.





The big difference is that most of the older clamp on switches didn't have brake lights and you had separate turn lights front and rear.
