We tapped into the WHITE wire with the Tan tracer for the brake light signal (red wire on the controller) Test to be sure, it must power on when the brake pedal is pushed.
Battery feed was taken from the battery (under the hood)
The Ground wire (white) was grounded under the dash (see screw in picture )
