ok...rookie mistake, do i need the dash harness, or engine harness, to make the gauges work? The harness under the hood is brand new, and also the one in the dash....and from I can tell/understand they are for a 99+ style Ram 1500/2500/3500 (that information is from Chrysler). Thinking about selling and just buying something less of a headache, this is going to consume my pocketbook to heavily I fear..
