So, I have a 1983 Camaro Z28 H.O. The gauge cluster does not work properly, which is the 140mph model. Firstly, with the key not in the ignition, the Tach, speedo, and battery needles are misaligned backwards.(See pictures attached) When the turn the key to power the electronics the needles shift, and then when I turn the headlights on the Tach and battery needles align themselves. With the headlights on, the right blinker is dimly lit(although it still works). When driving the Tach goes backwards and the Speedo needle works but is shaky.


Lastly, the blinker doesn't disengage when I turn the wheel. The owners before me had done some rewiring (obviously wrong) and I was just wondering if anyone had wiring diagrams and or knew what they did wrong.
