4 speed console wiring question?

Yes all 67 and 68 have the same harness. 69 also has a harnes for light and lighter. I am sure I have several of each . But getting to them may be a project. I also have the special short lighters for the console. The 69 and up harness is 3 wires and plugs in near the radio. one wire is a ground, 66-68 have reverse lights on the shifter.
