I am trying to learn how to install a float system on my well. I have an 80 foot deep well. It has a submersible pump which puts water into a holding tank. This water is then pumped to our house with a top mount pump. I have to plug the well in each time the tank gets low. Is there a way for my to install a float to make the submersible pump kick on its own when the tank gets low? I think the its 220 volt.

It is called a pump up float switch. But if your well has a chance of running dry you also need a Cycle Sensor to protect the pump.

With a 1/2Hp well pump you can just wire the float switch to one of the two hot wires to the pump. On larger horsepower pumps you may need a relay like is shown in the wiring diagram on the cistern storage tank drawing.
There exist float switches with piggyback plugs.
What is a top-mount pump? You are referring to an above-ground pump that is topside that fills the cistern vs the submersible one shown in the illustration?
You would probably splice the pigtails in an electrical box if you don't use a piggyback plug.
The high float switch will not connect to that pump.
You could have a second low float switch that keeps the top mount pressure pump from pumping if the cistern is empty. In the illustration, the right-side Cycle Sensor does that job.
This is similar, but is using a submersible pump in the cistern as a pressure pump:
