the ciggie lighter should be fused already, surley you won't need to fuse it at all!

but the ciggie lighter is more then 15amp i think!

i'm sure it's fuse number 3 which is rated at 15amps (ciggie lighter/radio/clock/interior light)....i realised it's already fused but like to be over cautious......lol.......i might put the inline fuse between the switch and horn then

but if it's already fused, it ain't worth the hastle!

if i blows, and it's likely to (cos it's running so much) it will be a but of a fucker to change it.

Got my horn back!!!............i found some spare permanant live spades on the back of the fusebox, fitted an inline 15amp fuse between the spade and the push button i've fitted into the dash, ran the negative straight to the battery and sorted !!

time to book an MOT !!

Good job m8
