ok so i got some autometer gauges from a buddy. he got them from some other guy so i cant get the sensors. i have the electric oil pressure and the electric boost/vacuum gauges. they are autometer cobalt series. is it possible to wire the gauges up to factory sensors on my 93 GSR? like hook into the factory map sensor for the vacuum gauge and hook into the factory oil sending unit for the oil pressure? or if its possible to buy the new sensors from autometer should i do that?
