PROGRAMMING BUTTON DOES NOT OPERATE
The programming button is used to set up your gauge and must be used for the gauge to be properly calibrated.
To enter the programming functions, power on the gauge, as the pointer is coming back to zero, hold in the button.
Does the gauge power up and do a full-sweep self calibration?

Check the button for proper connection:
One side of the button goes to 12V +
The other is connected to the WHITE wire
Pull the plug, probe the WHITE wire pin with a multimeter or test lamp to verify that there is 12V+ on the line ONLY WHEN THE BUTTON IS DEPRESSED
