i'll ask my roomate to look at a schematic if you have one.. but if i remmeber right the cluster didnt have any chips on it.. it was all analog which would probably mean that the ecu is modulating the voltage to adjust the gauges. might be tricky to do w/o fubar'ing the cluster.. if you have the schematic i'll gladly run it past him he designs heart monitors for a living i think he could handle this
