Dumb question, what happens when you push the brake pedal. Do the lights go out? If so you may have your brake switch installed incorrectly. I have a brake switch and a clutch safety switch, but it is the same switch for both (it has two sets of prongs, it looks like yours only has one set) . The clutch safety uses one set of prongs and the brake switch uses the other. I had to test mine with an ohm meter to make sure I had them installed correctly.

You might also call the technicians at Ron Francis, they can be helpful. Just make sure you have your harness edition when you call. It should be the letter on the bottom of your chassis harness instructions.
