<VV> court lamp hookup?

[Kirby Smith]

The front floor courtesy lights (contracted to "court" lights on the 
Shop Manual schematic) used on Corsas connect in parallel with the dome 
light.  The connection point is under the headlight control switch.  The 
courtesy lights were designed as an add-on to the base light wiring 
circuit.  I expected therefore that the courtesy lights connectors would 
  connect to the dome light power leads and provide a way for the dome 
light circuit to be added on.

The power wires from the headlight switch, the dome light wires, and the 
courtesy light wires have single terminal connectors.  Two into one 
don't go without an adapter of some sort.  I can't recall now how they 
were originally connected when I took them apart 30 years ago.  I can't 
find any plastic plug-based 2-into-1s in my once-removed but 
not-yet-reinstalled parts piles, :) and I can't find any hard metal 
2-into-1 GM terminals lying about.  (If they existed, these would be the 
counterparts of similar devices that are widely available for use with 
crimp-on connectors. Which is not to say that they don't exist.)  I 
could wire up a connector based system, but I would really like to know: 
How is this conection supposed to be made?

Thanks
