Need electrical guru

I have swapped a later model BB into my 1970 BB car. In the process, I replaced the engine harness as well as the heater/AC harness. To accomplish the later, I had to remove the center instrument cluster. NOW, my fuel gauge is pegged past FULL. Anyone know what wires I have crossed? All the other gauges work just fine.

Just got the new engine fired today and it lit right off. Just need to fine tune the timing and Holley carb settings.

Give the glass with a few taps near the fuel gauge. I guarantee that it might work.
