1972 Dash Brake Light

[kna4977]

Was messing around in the engine bay and the electrical plug that goes on to the switch on the master cylinder didn't seem to be fully on, so I pushed it down to where it would seat. Dash brake light came on and stayed on.

Took the plug off and someone at some point had put tape on it I assume to keep it from staying on all the time. I retaped it and put the plug back on. The dash light comes on when the key is first turned on then goes off like it should. I believe this is how it is supposed to function, but don't think tape would have ever been involved originally. What do I need to look into to get it working like it should when fully connected without tape interrupting the circuit?

As far as stopping goes, the truck does like I think it should.
