Hello I will help,

You should have a light green wire in that connector that gets 12 volts when you step on the brakes.

In practice you can tie the brake controller feed wire to any of the brake light wires coming out of the brake switch.

Let me know how I can help you with this

Thank you

I assume that is the hot wire going into my control box I need the wire after my control box has controlled the voltage to the brakes

The wire from the controller to the trailer connector is the dark blue one in that same connector.

Let me know how I can help

Thank you
