Ok, to know where everything goes:
Fill up the gas tank. Note the position of the gas needle.
Take the car out for a good drive and note the position of the temperature needle when the engine is at it's normal operating temperature.
At idle, note the position/rpm of the tach needle.
As soon as you get back, take all needles off and note which goes to what.
Turn key to on (important!)
Place gas and temp needle in before noted positions.
Turn key to ignition and start car.
At idle, place tach needle in before noted position.
M/KPH can be found through the diagnostic mode with the fuel/units/reset button combination. This is the trickiest part of all. I've tried the way that the companies said to do it but it was never even close to being accurate. So, I took it out in a vacant parking lot, put it in diagnostic mode, and drove straight at a slow consistent speed. By looking off of the display, you can place the needle exactly where it needs to be. It may take a couple of times to be perfect.
I hope that helps.
