ok, i want 2 get my horn working, the relay has been removed and there is not much wiring i can see...

i chnaged the horn so it doesnt earth through the body of the horn like the old ones so it has a + and a -

i know i can just run a positive to the horn and switch the negative but am just wondering whther i need a relay?

cheers

relay is just so you can run a thinner "trigger" wire back to the horn button, it is not needed. but you may need thicker wire to run to your horn button and back without a relay (not that i can imagine a horn pulls many amps?)

well most of my wiring is already 2.5mm cause i had 2 rewire a fair bit of it... 2.5mm is pretty much double the usual wiring for it, but i got the wire free so itsno biggie
