I know this was covered in a minor way a while back. I'd be keen to replace the standard lame horn on my 500. Is this an easy DIY job? Do I need to remove a wheel to gain access to the horn ?

I'm planning the same thing, the standard horn's just feeble. I'm looking at a compact dual air-horn such as a Wolo. The factory horn's deep down below the DRl on the passenger side and as far as I can see it'll need the front bumper off to gain access which I plan to do when the weather improves a bit as I have to work outside.

I've heard the bumper stays on but the front left wheel comes off as the horn is just behind the wheel well...

That may well be so given it's location, I would certainly hope so. I've had a wheel arch liner off but that was the driver's side. There are other reasons I want to take the bmper off but I won't be doing anything till the weather warms up a little.

The horn should just be a swap-over but we'll see when we get there. The existing horn operates from a 15A fuse which wouldn't handle the power of the new one so I think I'll fit a relay and use the existing cable to switch it, taking power direct from the battery. On the face of it it looks pretty simple (famous last words...).

I had to change the front passenger DRL a couple of months ago after a bird strike (wood pigeon direct hit on the light at 70 mph broke the three fixings off the DLR unit!).

This necessitated taking the front wheel off and then removing the front wheel arch liner (not completely off, just removed the fixing screws/nuts of the front half and carefully bent it back).

In the process of doing this it exposed the location of the horn, I hadn't seen it before (!). From what I remember it looked pretty easy to work on, and passing a wire up to the battery for a main feed should be a nice short run.
