I can say thank you because I needed to see what the three connections on the bottom of the gauge were. I got one that had no instructions and no markings. This helped me with what I needed. I understand what the others are saying with grounding the body of the sensor but I didn't need to worry about that part anyway, it was a retro-fit.
The hot wire is the wire going into the gauge. The ground is the cylinder head or in this case the pot. No ground wire to the pot and the juice can't flow.
You need to hook up the negative to the sending unit to make it work.

you missed a step. The sender has to be part of the circuit. you need to ground the base of the sensor also. That is why you are getting no reading.
Maybe the gauge is in Antartica at minus 180dc so it will take time to reach positive 100dc in 2 days or so keep boiling

I hooked up the negative to the sending unit and grounded the sensor on the car. Still does not work. Checked twice all connections. Needle 120⁰C
Sending unit isn't grounded
Please explain wiring
Te falta el negativo en el sensor
मेने प्रयोग किया लेकिन सही नही हुआ
पूरा सही बताई प्लीज
Ye and it's not working
Naths Aquatics u need to ground sending unit
kuch bolo ya bhonko bhi saheee ? kiya btana chao rahay ho ?
