last week i bought 3 aftermarket gauges for my 97 eclipse 420a engine. the gauges are oil pressure , oil temp, and the vaccum gauge, i am asking do i need to buy sensors for those gauges or the car comes factory with it ???

 

the gauges should of came with the sensors and wiring needed. im a little lost tho what is the vacuum gauge for?

 

yea those guages are just a waste of money for that car. Maybe i can see and oil pressure guage, but the other two i just dont get.
