The side of the harness connector that is showing in the images is one piece. Delphi part number is 8900675 .
The side you are missing is actually comprised of two separate connectors. Whether you need them both depends on whether you are still running a fast idle solenoid on your carb.
If not, you only need the connector that plugs into the bigger cavity on the left. It then heads straight down the inboard side of the valve cover and plugs onto the compressor clutch coil two pin terminal. That shell part number is Delphi 2977253 use terminal 2965142:

The shorter one (on the right) is the connection for power to the fast idle solenoid. If you need that shell, it is part Delphi 2984528 and use terminal 2971962.

These connector shells and pigtails are on the shelf everywhere:

They are sold separately and wicked cheap (like $.20 each). When you get them, just assemble the terminal to the shell and then splice the pigtail to your existing harness.
