Installed this today. Pic is still a "preview" as I have to trim the surplus cable now that everything is in place. Also have to re-attach my camera, and will see if I can rig up some sort of cable guide on the back of the fork or lightbar.
Can't find a listing on eBay for the whole kit I bought which included wiring, relay, connectors etc but its a model 419 http://wolo-usa.com/air.htm
. The sound on the clip on that site is pretty accurate. The wire and connectors that came with it seem a decent quality and the relay works with no delay - time will tell how reliable it is. It also keeps going at the same volume unlike my current one which has recently started fizzling out after a second or so. I did have to go to Halfords to pick up a 25A mini blade fuse as it was supplied with an in-line blade holder (and fuse) but I am firing it via a Fuze Block under my seat. Its nice and loud but not in a
off out of my way way. I was a bit concerned about that because often I only want a please notice that I'm here beep without coming across as aggro.
I saved a good bit on the height by turning it sideways and making a Z shaped bracket. The bracket is screwed into the original location and then bent up in front of the bottom yoke which allows everything to sit a little higher. It could go a little higher or be angled further forward but I had to clear the light bar. The location of the live wires in the pic give a good indication of where I mounted the relay.
Might even have time to wash it tomorrow if the weather is ok
