It sounds like you are having a problem with the stoplight switch (red) wire on your Draw-Tite Time Delayed, part # 5504. If this wire is not connected properly to the right wire you will encounter the problem you are having.

I would make sure that the red wire is connected securely to the right wire on your vehicle. I would recommend you use a circuit tester, # PTW2993, to check for voltage on the wire when the brake is applied and no voltage when the brakes are not being used.

I attached a link to an FAQ page on wiring vehicle for a brake controller from scratch that you might find informative.
