on my 1980 cutlass calais i am trying to get the rally pack dash to work and the book nshows two connectors and the back of the gauge package has spots for two connectors but i can only find one connector am i missing something? and what gauges years wise will fit? my temturatue needle fell off and broke and so did my voltage gauge and my trip meter reset is broken if i could find new old stock or just used i would use it. a wiring diagram for the dash would be nice.
