I have Autometer Nexus Gauges. Not the ones to get if you're cheap. They are expenssive but I LOVE them. They are easy to install because they actually have a control module that you install under the dash and all the sensors plug into it and one wire goes up to the first gauge and then they daisy chain from there. The gauges work perfect and have never stuck. They use a stepper motor inside. The cheapest place to get them or anyother Autometer Gauge I've found is from www.thunderbolt-motorsports.com who is a seller by that name on eBay. He's a good $50-$100 cheaper per gauge then anyone else on the net. I searched them out long and hard before I bought. I have four in Carbon Fiber Pods on top of my dash. EGT, Oil Pressure, Fuel Pressure and Nitrous Pressure. I'm buying four more from him and a four pod pillar. I'm getting Trans Temp, Water Temp, Oil Temp and Boost. You can see a demo of the Nexus Gauges on their site.
