Where does the horn button wire enter the steering column?
Now that the rusty ebay horn with bracket is on the way, I need to figure out the rest of the installation. The horn I have tests and works well. I installed a new horn contact bushing (plastic thing with spring loaded brass ends) and the brass contact plate on the column is clean and shiny all around. I installed the new springy round thing in the pics above.
I have not unwrapped or traced the existing horn wires.
I can't tell exactly how the wire enters the steering column to connect to that brass collar someone posted earlier.
