I can't stand idiot lights and I don't want to replace the speedo on the truck so I am adding a Tach, oil pressure, water temp and voltage meter.
Here is the way I mounted the oil pressure and temp gauge:
The panel isn't mounted yet so I can paint it. The temp stays at a constant 185. The oil pressure sender isn't hooked up yet. I had to use PB blaster on the water temp sender to get it out and it hasn't soaked in enough on the oil one yet.
I'm pretty happy with the way it looks. I have something special in mind for the tach install.
