Question about temp sending wire
Willcox has a series of tech tips, some specific to your gauge/sender, here:

"Missing insulating washer on gauge" shows 150 F in the example photo. I don't know what that means though. You may want to also confirm your temperature with an IR thermometer.

the reason I ask is many replacement sender units are way off delivering the correct resistance at various temperatures.
As said Willcox have some great docs with info to check it out but in simple terms.
you can check the gauge is displaying correctly by removing the green wire and using resistors of various values from the green wire to ground and see if the gauge itself is showing correctly.
that will tell you if it’s a gauge problem or more likely the sender at fault.
