Horns Operation
When one of the horn switches is pushed an earth path is completed from the horn relay coil on a PO wire from the engine compartment fusebox, via header C0291 LHD/C0286 RHD, the rotary coupler and horn switches, to earth via fixings E110.

The completed earth path energises the horn relay coil closing the relay contacts. The feed from fuse 16 passes through the relay contacts to the LH and RH horns on PG wires causing the horns to sound.

The LH horn is connected to earth point C0564-1 on a B wire. The RH horn is connected to earth header C0018 on a B wire.
