Well its a little screw behind the speedo... You have to take the whole speedo out, disconnect all the cables from it, they just pull out. Then its just a gold screw directly behind the speedo, so looking from the front, it should be down the bottom behind the 0, but on the back..... you'll see it. The screw is really small and either gold or silver and you just unscrew it and take it out. It should be near a light bulb on the back. Hope this helps but its really hard to explain. Maybe you want to meet up or something. Where abouts in Syd do you live. **** I just read that yours is a 1999 and I've got a 95, maybe its the same. Ask envy imports 99074144, I took mine out and asked them which screw it was! Or they can do it for $30.
