How do you do this, I installed some white face gauges and some of them wont move, when I start up the car it jerks a couple of cm's but really doesnt move from there.

 

Make sure your cluster is plugged in all the way first. I'm going through the same exact problems as you. The speedo cable is a real pain in the *** to connect well. My tach is idling at 0, but moves smoothly, voltage works fine, temperature is stuck, fuel seems to be stuck, and the speedo isn't working either. I'm workin on it though, very frustrating
