Looking at the electrical diagrams in the Bently manual there is a change in the horn relay 2001 MY. It appears that the later model for the 7.2 DME may have added a diode and is directional where the earlier is not. I don't have a schematic for the later ignition assembly to compare to, but Maybe try an earlier Relay? Hey Particlewave what do you think
