Odd wires

[sdebaker]

1977, non-California, 1800 Spider.
In engine bay, left side, two wires that are not on the wiring diagram in my owner's manual -- light brown with green tracer, paired with dark green. The ends of the wires have 90-degree, female connectors.

What are these?

You might try this diagram and see if it's the same one you have.

Likely went to a temp sensor under the intake manifold for the emissions control system.
