Im not sure If ya'll are familiar with the Dodge ram overhead console setup.......in my dads 2002 Ram 3500, it has a overhead console that displays the temp, your average gas mileage, miles till empty, and compass. Is there a way to hook up one of those so that you can have your gas mileage and stuff shown as you drive? Im wondering if its factory calibrated, and cant be changed, or if its like the simple vacumm type gauges that you hook up to a vacuum line to use to tell when your getting your best fuel economy. Im trying to come up with a mod that is somewhat unique and doesn't cost alot to do.
