My backup lights on my 68 Camaro are disconnected. There is a wire under the car connected to the lamp housing. Today I was cleaning the trunk when I found green wires running from the taillamp wire-bundle, one on each side. Could these green wires be the ones to connect to the backup lights. I guess the lights grounds itself. Through what hole in the trunk can I pair these wires?

Correct, they should be light green.

Got it solved
