grounding actual sensor for water temp gauge

[300hpbound]

There are NUMEROUS threads as to where to install an aftermarket water temp sensor for the 1g, but that's not what i'm having an issue with.

I have the gauge completely wired in but it still doesn't work and I know that it's because I haven't grounded the actual sensor itself. But frankly I have no idea how to go about that. They say in the instructions that "the sensor is ground through the threads" but I don't think they understand we still use pipe tape or permatex to make sure it seals so I have no idea how to ground the sensor. Could someone snap a pic of how they ground it or give me a little detail as to how to go about it?

It's an autometer pro comp electrical gauge by the way.

Have you tried leaving a few threads exposed at the upper end of the sensor? This should be enough to allow for a good ground. You may want to test ground it with a piece of wire to make sure it isn't already grounded and you have another problem. Normally, teflon tape will allow the threads to 'bite' through enough to still allow grounding of the sensor... Unless you are trying to build the threads up by 1/4" or something.
Otherwise you could solder/ wrap a wire around the body of the sensor.

Thank you for the response. after talking to a few people that I used to work with they stated the same thing, it should have grounded even with the teflon tape around the threads. I re-checked all my wiring and I think I just don't have a solid bite on the wire i'm tapping off for switchable 12v. I'm going to pull it apart and solder it so I know the connection is good. Otherwise the light works so I know that's fine and the ground is dedicated which is good. And I know the sensor is easy enough that it's wired in correctly so i'm going to check my power tonight and hopefully it works. Thanks for the help man
