Fuel gauge after motor swap

I have a 98 wrangler with a 99 dodge 5.9L swapped into it. For whatever reason I cannot get the fuel gauge to read at all. Sometimes when I turn the car on it will sweep all the way up and then quickly drop to empty and the low fuel chime will go off. First thing I did was clean up all the connectors and the ground, that didn't work. Then I replaced the pump thinking it was the sending unit, that didn't work. Replaced the relay in the fuse box, that didn't work. Continuity from the main harness plug to the gas tank reads good on a multimeter. I am at a loss as to what else I can do. I know I can always get an aftermarket gauge, but I would really rather keep the 'stock' look. Any help or recommendations would be greatly appreciated.

Mods: if this is more suited for the electrical forum please feel free to move it.

That is part of the harness that is modified to run the dodge pcm. My guess would be somewhere in the
harness between the pcm and sending unit. You will need the factory service manual and get the pin outs at the
pcm connectors to verify where each wire is going and to make sure it is correct. Good luck.
