Im trying to hook up an after market tachometer and i have the fill a pod gauge set that attaches up by the window of the driver door. I want to hook up the engine temp, oil pressure, and trans temp gauges. Is there some kind of book that i can buy from you that shows me where to splice the new gauges to? Like i found a diagram that has the tach output wires labeled and how to install it, but i cant find anything for the other gauges on where to hook them up. Do you have a "stock wiring gauge output" book or something like that?
