There is the matching plug under the dash in front of the dead pedal.

Brake controllers come with a similar pig tail for the controller. You have to know how to match the wires up. Popular controllers might sell a ready made cable from their controller to your car and you won’t have to make one.

This is probably the most common brake controller company. I have a P3 and had to make the cable. With my Jeep I could buy one ready made. They might have them ready made for Tesla now. Not sure.

Plenty of threads and videos around on the topic.
