63' electrical question?

[ABX131]

It looks as though the original wiring harness was removed and an EZ wiring system unit was installed. The only thing that works and is hooked up are the headlights, brake lights, ignition and anything to the engine required to make it start. There is a trio unit of guages under the dash that also works but nothing in the actual dash guage cluster. My question is regarding the factory knobs along the bottom of the dash. The first is the headlights, in order, what are the rest? There is one unit missing, the ignition I assume because the key is in the column now...
