i have a 1980 olds cutlass calais with the gauges package. the gauges do not work so i took them out about two yrs ago. then life caught up with me,got married etc. now i am working on the car again and noticed a few things missing like the tempurature gauge needle and the volt meter needle minor details if sure. all the diagrams i see show two male plug ins for the dash and there is a spot for two plugs on the back of the gauges but i only have one male plug is this right or am i missing something? help!!!
