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.

Got it working!

An electrical genius I know was able to come tonight and spent about 4.5 hours tracking it down. He knew it was going to be something stupid, but not sure what.

He came to realization that it was ground related pretty early on. Then just started tracking circuits.

To avoid blowing fuses, he took an 1156 light socket and bulb and ran that between the to ends of the fuse. This way, we would have power, but not enough to do any damage.

Turns out that one of the light sockets had shorted out. I have removed the light socket for both the flashing brake light and, I believe, the flashing seat belt light.

With the new relay, I've now got working turn signals!

My hazard light switch appears to be damaged so I'll have to source a new one of those, but it doesn't affect my ability to drive the car. I've also got to replace my high beam/low beam relay as it is sticking.

I'll post some pics tomorrow. I was wiped out and left the workshop a mess and the car in pieces. But happy!
