Has anyone ever installed after market gauges on thier Rodeo? I was wanting to add an oil pressure and maybe a voltage gauge to my truck and wondered if you guys might have some suggestions. I have never done this I wonder what all is involved, I think I can handle the voltage part but not sure about how and where the oil pressure gauge would be installed.

You can also try Autometer. They're pretty good.
