Here is a work in progress of my friends 09 civic coupe. He wanted stealth gauges so I made them in the center console pocket. The gauges are hidden behind tinted glass so they aren't visable when off. The gauges he wanted were Oil Pressure, Oil Temp, and boost. Also I added a PLX M-300. I modified the Plx unit so it would have a remote display so it can be mount virtually anywhere in the vehicle. He wanted the gauges to dim when he put the parking lights on so I made a circut to drop the power to the gauges so they weren't so bright at night. Also he wanted it so when you park the car somewhere you can put a lid over them to cover them up. I made three plates for him. One is 2x2 twill carbon fiber, one is 2x2 red kelvar, and the last is yellow kelvar. Here are some pic(not the greatest but you'll get the idea)
