I think what you need is a VDO 323-057 AKA Dakota DIgital SEN-04-1. It has the connector you want.

This is supposedly the same electrical characteristics as the gazillion universal ones on Amazon that have the wrong connector, some as cheap as $5 or less.

If this graph (posted elsewhere on this site) is right on though, it is gonna read a little high, maybe 20F, but it is the best I could come up with.

VDO also make this: https://www.amazon.com/VDO-323-050-T.../dp/B001P76H3G

It doesn't hit the graph above as close, but it is off in the opposite direction, so if the other one is way off, it might be something to try. Because it reads a little too cold I might boil it in a pot with a gauge hooked up, just to make sure it isnt reading so low that the gauge doesn't alert you. It might be.
