Troubleshooting my electrical issues., My first problem was blinking red light on the dash for brakes Options

Edit: Renamed the thread because what started out as one electrical problem has led to others and I'm hoping to capture all the information in this one thread.

Initial Problem:

When I turn on the 72, the red light on the dash (in the top part of the gauge on the left side of the dash) blinks and won't stop. I've made sure the e-brake is all the way off. I'm wondering where is the switch that controls this light?

I've read that when the brake master cylinder is replaced, there is a switch on the MC that needs to be reset. I used a MC from Rock Auto and there is not reset switch button. Only the electrical switch that activates the brake lights.

I have a brown wire that is connected to nothing in the area of the e-brake handle. I've tried grounding it but the light still blinks on the dash.

Any advice would be appreciated.

Update:

I was concerned that maybe I did not wire up the new relay for headlights correctly. Rechecked and is correct.

I didn't realize this at first, but it isn't just the tail lights that are on, but also the headlights. I didn't notice before because they are retracted, but they are powered up when I have the battery connected to the car (even without the key in the ignition).

I tried removing the relay all together, and the head light and tail lights are still on all the time.

I started checking the ground locations. I found one at each headlight, and one close to the relay board. They all look good and no broken wires.

Now I'm wondering if maybe the headlight switch has gone bad? How would I test that theory?
