This is my setup:
The instruments are AutoMeter liquid filled, clocked so that 'normal' is needles straight up and down.
At the 1 o'clock position above the water temp gauge is a yellow LED that comes on at 205F and goes off at 190F.
At the 11 o'clock position above the oil pressure gauge is a red, blinking LED that comes on at pressure less than 25psi.
The fuel gauge is stock and mounted behind a thin pane of Lexan. The G2X is mounted on aluminum standoffs to bring it closer so I don't have to reach so far to set it.
The two red lights indicate which engine map is active, both lights off mean In the center of the dash, the top red light is alternator, the bottom one is CEL.
The gauge from the LC-1 air/fuel is mounted on the windshield with supervelcro. It's a great spot for it since it is only 10mm thick.
