Ok ive tried to do this off my cluster so i can use the digital read outs of the tach, speedo fuel etc but i cannot get it to work. I need it so i can set my gauges since i just replaced the faces they are off a bit. I inserted the key pushed and held the button rotated back to accessory and dont get test in the odmeter. What am i doing Wrong?

>>how to
>>scroll down

press and hold the odo button down before inserting the key. start the car up and keep holding the button. it'll take a sec or so before the gauges sweep, and you're alowed to scroll through the options.

Turn the car OFF. Push down and hold the odometer button, then turn the ket to ON. WAIT there, still holing the odometer button down. It takes a few seconds.
When it says "test" in the odomter, let off the button and the gauges should sweep. Then go ahead and start the car, and it should stay.
