New Temp and Fuel Gauge Problem

I replaced the gauges with whatever is supposed to be a direct replacement for the OE. I think I bought them from Classic Industries, but I can't recall for certain. My cluster also has that little capacitor with a single spade terminal on it. It is plugged into one of the sockets that the IVR plugs in. Guess I will start with a new IVR first and then see what happens.
