OK....Fiamms were $16.00 and had red covers....sprayed them black with hi-temp satin black.
Installed 12 gauge hot wire Yellow to Black] with inline 10amp fuse direct from battery and ran the wire up the centre tube...
...to the relay mounted top right rad bracket...used 14 gauge from horn to relay + shrink wrap
Using the original horn mount
and end result...
Sound great - low + hi tone........
