OK, I have to share a little story here... and add this as a little bit of trivia for anyone else who disables the horn by pulling the fuse...

I am now the proud owner of Joe's Isuzu. I also live in California, where they have lots of weird smog/emissions requirements. So, off I go to get the VX "smogged" so she's legal here...

The mechanic hooks up the fancy machine, and starts to look puzzled. He calls me over and says that the VX is probably fine, but it just isn't communicating with the system. Seems that sometimes happens when someone plugs something big into the cig lighter or something, because the emissions communication stuff is often in the same circuit as the lighter... sometimes a fuse blows...

Well, that reminds me... there is that matter of the horn fuse...

So, I tell him about the horn and that the fuse is pulled. We replace said fuse, the poor thing starts screaming (inside a concrete block bay, no less) but voila! We have communication with the testing machine!

Fortunately, the mechanics and (most) other customers were very patient, while the poor guy has to do the whole test with the horn blaring. (For you non-Callifornians, this is about 3 - 5 minutes but seems much longer when someone is sounding the horn in an enclosed work bay!)

His only real comment about it was "you know, you might want to have that fixed..."

Ya think? Well, I have two years before the next test anyway...

So, the Dragon passed all the emissions tests with flying colors, and is now a legal and legitimate citizen of California! Whew!
