Brake warning light, The quest for success continues Options

[PaIsa]

So I am back trying to get my brake warning light to work properly. The situation before I started searching for the solution was the following:

Brake warning light was always blinking whatever the car condition. Blinked with the ignition ON. Blinked with the engine running and hand brake applied (normal). Blinked with the engine running and hand brake removed. Blinked with the engine running, hand brake removed and MC wire disconnected. So basically, blinking all the time!

So I was investigating the emergency (hand) brake wiring. Remove the seats, center console, etc. Looked at the emergency brake switch and seemed to work OK. There was a contact (closed circuit) when the switch was in position where the emergency brake would be applied and no contact (open circuit) when the hand brake would be removed. Looked on the wiring for evidence of short to ground but was not able to find anything. The wire goes in the center tunnel and is accesible until the shifter where rather then following the main wiring harness and the speedo cable, it goes under and God knows where it goes!! So I was not able to follow it all the way.

Now I have some disconnected wires near the brake fluid reservoir (already a thread on this trying to understand where these should go). The wires are brown-white and brown-white connected with a brown wire. The brown-white wire that is connected with the brown wire is cut.

So after I reassemble the emergency brake wiring, I did some test again.

Ignition ON, the brake light comes ON. Whit the engine running, no more brake light blinking.

So now I tried with the cut wire (the one near the brake fluid reservoir) reconnected. Brake light blinking all the time. Disconnect the wires, no more blinking when the engine is running.

I am lost. Even writing this I am not sure if I am right with the tests I did and the results I got.

Anyone has any advice? I looked at the wiring diagram, but not sure!!

I would like to have this working but don't want to go crazy with this!!

The car is a 1972.

With no key in the ignition, the "parking light" feature of the turn signals should come on when the turn signal lever is up or down.

Someone has been mucking with the wiring.... That makes it even harder to figure out WTF is going on.
