My garage man is getting me a new horn and he has asked if it's 1 or 2 wires. I can't see as 1) it was pitch black an hour ago 2) as you know, it's right inside the bumper.
Thanks in advance.

Yep 2
Thanks people - I knew I could rely on you 
The horn circuit is a constantly live system. The horn button switch on the steering wheel earths the circuit, so if installing another make sure you don't connect a wire up and have the new horn sounding continuously like I did in a Maplin electronics car park
There will be a + and - on the terminal just make sure the wire you take off corresponds to the other unit when putting back on.

All well and good but if installing a relay like I did, you'll need to connect the +ve side (or a live connection) to the +ve input on the relay and the -ve on the relay to the -ve side of the horn and not just to a -ve earth or you'll have a constantly sounding horn!
Won't need a relay if replacing with original type horn....as it should already have one.
I was being careful, Almost set the 750L alight when I installed the grille spots without a relay
, and as I was fitting a rather powerful set of twin air horns out of a 80's Ford Serra thought I'd be careful and play it 'better safe than sorry'
There should be a horn relay already that the horn passes through? although I'm not 100% sure....
Might be, but if so I don't think its on the fuse block.
