Hi all.
Does anybody have a wiring diagram for the twin horn setup on a 1978 6.9, please?
I want to check the wiring of the switch that turns one of the horns off.
The previous owner cut the 2 wires to one of the horns and only had one horn working.
I have replaced the wires to the second horn and now both horns work, but now I need to know where the wire from the switch on the dashboard goes.
It comes out of the fusebox and then stops.
How I hate it when wiring is messed up!!!!!!!
