Thanks to Hornblasters.com, I have successfully installed K5 540 kit on my F150 Harley Davidson in China. Fast shipping, quality product and friendly customer services are the advantages of this company. I have no dissatisfaction at all, and will recommend their product to all truck lovers in Asia.
Welcome to the forum!
Wow! How about posting up some pictures, I have a customer over here in the UK, putting horns on this!
When you say F150 Harley Davidson you mean this?
When I read your post I initially thought you might be installing a K5 on a Harley bike… I think Stinky was thinking along same lines. 
Oooooooohhhhhhh!!! (I kinda feel a bit more stupid than I normally do now) lol
I read it the same way! lol Post pictures:)
