76 dart temp gauge problems!

They both have the same number of light slots and the same place for the resistor only difference I can see is the way they use the bulk connection with the boards paths.

Who knows what result you would get. HI BEAM blinks for right turn ? Fuel level increases as engine warms ? A blazing fire ?
The 76 inst' panel is different from all others. It's circuit board is too. Good luck with it.
