ive hooked gauges up on plenty of cars, but they have all been mechanical. and these new ones i bought have peak, and high and low memory warnings. so once i find out which ones are which, i splice and shrink wrap them with those special wire connectors? and would anyone know an easy point thru the fire wall? and MikeR someone told me you were the guy to talk to about sending units? where could i hook up the oil pres sending unit, someone told me under the oil filter there is a place to do so? And for the water temp im gunna splice the radiator hose and buy one of those adapters, is that a smart idea?
