Hi Brian,
Yes where your arrow is located, is where the bulb w/ mounting bracket is screwed in. When you took the car apart, there should have been a little gold star type washer that nests between the bracket and the deck lid to create a ground.
The wire is routed to the left of the decklid, down and out the round hole (bottom left). the smaller hole is for the mounting tab that secures the wire to the decklid before going into the trunk.
In the attached unrestored Silver Jade picture, you can see the tab of the trunk light bracket and mounting screw placement inside the decklid.
In the attached unrestored Wimbleton White picture, you can see the routing of the wire out the bottom of the decklid.
Hope that helps!
