A cruise servo does require a ground. As I recall some were self grounded through the housing to the inner fender and the later servo's had a wire.

Definitelly not 70s which are the ones for this harness period by the PN ( and that's why I said that ), maybe 80s/90s. This is definitely an underdash harness, but cruise control? dunno. I can't see the plug for the control switch which these harness get. and those 90 degrees plugs, it seems to be for some cluster gauge stud... Just thinking out loud.

That might give a clue to where the different plugs go. It looks like the flat connectors and the bent end ones aren't grouped together so they could go to two different areas.
