81.4/5Ω is within the range I'd expect for either one so whichever one you were measuring sounds like it's okay.

That was with the resistor on the back of the gauge still on it, no nuts or connectors. From one stud to the other. I couldn't figure out how to remove it (the resistor) as it didnt come out easily and I figured I would crack it if I tried to pry on it.

Hmmm? The overall behavior of the needle swinging to the left with the sender plugged in & key on and moving to the right with the sender unplugged sounds normal. But the needle positions seem out of range.

Do you know if the procedure of retrofitting that gauge into your cluster involved removing and re-installing the needle? If so, there is a possibility that the needle was not clocked correctly when it was put back in place. It's simply a small round shaft with nothing to "key" the needle to a particular location in relation to the meter movement internals.

No I don't know, I'd have to ask a member here who did it for me.
So I also ran test leads instead of using the installed wires for the sender and 12V and ground. No changes.
I could run to Orielly and try a new gauge sender...
On the gauge if I removed it and adjusted the pointer... Hmmm, I'd have to know where to put it.
