After replacing the dashboard with a 100% identical replacement, the speedo, tach and some other gauges in the cluster stopped working. It lights up, engine temperature works, A/T indicators work fine but nothing else works. While I was trying to ensure that all grounds are connected using a voltmeter, one of the connecters to the combination meter is not showing 12V in the ground pin while the engine was running. Trying to trace where the grounds should be connected and noticed these 4 wires right under the steering column that are not connected to anything. I am positive that i didn't disconnect them. This is something from the previous owner. Would greatly appreciate if anyone has any idea where they should go and what should they connect to? Thanks!!
