It sounds like there are some wires installed incorrectly.

When connecting the red wire to the stop light switch on your Escape, it should be attached to the purple/white wire. There is another purple wire, but it has orange and is not the correct wire for the brake controller. You can also use a circuit tester like part # PTW2993 to check the wires for function.

Then run the 12 V black wire to the positive battery post using a 20-amp circuit breaker like part # 9506P.

The blue wire runs to the 7-way connector on the back of your Escape, and the white wire is attached to a clean metal surface for ground.
