Where does this harness hook up to?

If you look at the picture you can follow the wire harness to the grommet above the booster. The horn wires are there and connected, the electric choke wires are there and connected, the oil pressure sending unit wire is there and connected,as is the temp sending unit wire and it is connected also. the car is not running yet so I can't tell whats working or not yet. What I need is a member with a 1974 to look and see first if their car has this harness and if so where does it go? For all of you who have responded thank you but it's still a mystery. I do not have my A/C compressor yet and I am wondering if it has something to do with that. A picture of someone who has it would be greatly appreciated.
Thanks
Bob
