Here ya go Lee! Its a little pricey over the $20 gauges, but displays 4 sensors of choice at the same time. You have to buy each module for each input you want but has endless possibilities and is a sweet gauge.

This is also the gauge/wideband I will have in the Cutlass when I start working on it again. They also have a newer DM200 gauge that is larger and displays more, also a scan-gauge one that allows you to use their wideband with it to display wideband data at the same time as other scan data, pretty sweet setup and keeps from needing multiple gauges, but again pricey
