Wow I can't believe it's been over a year and it's still not sorted
Well I plan to change that in the morning now.
I have just received a pair of ultra loud twin tone horns
Looking at your picture Robin did you just splice into the existing wires to connect the new horns, leaving the old plugs in place?
Sorry if I sound thick, but am I right in thinking there is just a live and an earth in the original plug?
On my new horns there are two blades on each horn. I'm thinking one is live and the other is earth. So should be easy enough to wire up
