Padgett Posted February 24, 2016 Report Share Posted February 24, 2016 Had wondered when I saw that there were no markings on the '93 dial. Wonder more that it either reads "some" or none" and just those two positions which makes me thing it is a on-off switch. Question is what happens if you put a real pressure sender on the engine. Does it then give real reading or does it not work at all ? Anyone try ? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted February 24, 2016 Report Share Posted February 24, 2016 the cluster operates the same as 91/92, just that the overlay changed. if you stick an actual sensor in place of the switch/resistor combo that it probably has, then it will read "correctly".
