I am in the final stages of completing the restoration of my 230sl - built June 1964. I need some detail on what happens at the steering wheel to activate the horn. My car has only one (driver's side) horn and there are two wires connected to it. I will be adding the other horn soon once I procure it.
What wires should I be looking for on the steering column that would activate the horn when the horn ring is depressed? Where on the steering column do these wires exit?
Finally, for the passenger side horn, I believe other posts here indicate the wires pass from the engine compartment through a hole near where the air filter cannister sits. Where do those wires connect in the engine compartment - what part of the harness? Are they routed along the back of the firewall?
Any help is appreciated.
