Intermittent brake warning light
I have an intermittent brake warning light issue for a few months now. Disconnected the emergency brake switch and tested; switch is good and light still comes on with it disconnected. I should add the light is very random and sometimes fades on and off. I replaced the brake master cylinder because it's 20 years old, still comes on. The worst of it is, it disables the cruise control when on. Harness?
