The green is engine coolant temp sender. The "brown" is actually tan and is supposed to connect to an idle stop solenoid on the carburetor.

Thank you!

I have the same wire on my 74. Green is for temp sensor and the brown is for something else, not sure. It is hot all time key is on. In fact, it fell onto manifold and blew fuse for radio so I'm not sure what it goes to. I have an idle stop solenoid on mine that I connected to AC clutch hot wire so it is only energized when AC is on.
