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.

I've been doing some more research and did find a thread that had a picture in it and I spotted the switch. I circled it in this version of the photo:

Will also try disconnecting the switch on the MC.

Thanks to this thread for the help: Parking Brake Handle removal thread

Wow, talk about the right post at the right time. I just replaced my ignition lock and the big red light started blinking when I turned the car on. I was ready to start going through all the steering wheel connections when I saw this post. I'm a newbe and I never thought of the parking brake. THANK YOU for saving me some really frustrating time.

One maybe useful suggestion. The brown wire is pretty thin and could be easy to break. Mine's now under a thin strip of duct tape to make it more obvious and to give it some protection.
