Check ground wire, probably one common wire.
Make sure your dash dimmer knob is turned up.
Dash gauges in this year and a few others went through a gray or blue box controller. When things start to go bad in the box the gauges don't work and the box is unrepairable. Switch to direct read mechanical air gauges. All of the other gauges and function are available on VMSpc.
