Brake lights do not work

[Jtink]

I'm helping my neighbor install a turn signal, dlbrake light kit.
The turn signals were plug and play and work just fine.
However the brake lights are a two wire pedal.
It screws to existing pedal and wires connect in the floor.
However the brake lights do not work.
The wires in the floor are dead. They have no power, on my gas cart I had to jump two wires in the dash to send power to the wires in the floor.
This electric cart doesnt have the wires mine did.
Are there different wires I need to jump?
