Have you checked the connector right at switch for power ? Take a test light and look it to good ground and probe the brake light switch connector. One the two should light the test light. And the other connector if you connected the lights ground to, 12 v Positive, should light up a bit.


a multi tester would help to find where you have power and where you don't , everything needs a ground too , the brake light circuit may run through the directional switch depending on your set up
