I Just picked up a new cluster from the junk yard. Mine is an 87 this is an 88 but it looks the exact same. when I plugged it in the left blinker was on and the key wasnt in. not blinking just on. then when I went to put the blinker on the shifter light flashed then the right one and the ebrake light flashed. and the gas gauge wasnt working. What is going on. Is the wiring all different? anyone experience this? Do I need to find another 87 cluster only?
