Update
So I removed the instrument cluster and replaced the two printed circuit boards along with new LED bulbs and sockets for the dash lights. The fuel gauge was tested and found to be faulty. Replaced with another used one that tested good. Bench tested and everything seemed to work fine. Reinstalled in the car and my gauges all working properly. Not pegging to the extreme high reading. (Happy). Waited till dark to test the dash lights. Bench tested and they glowed bright as they still do now only problem is as I'm driving the headlights along with the dash lights flicker on and off rapidly. First guess is a ground issue. Any suggestions greatly appreciated. Really hoping not to have to take the instrument cluster out again. Ugh !!!
