After a few weeks of researching, talking to members here, and testing I finally have the first working wiring diagram to make a Honda Access Dusk Sensor / Auto Light (same thing, different name in different countries) work with the 1992 - 1995 Honda Civic.
This was tested on the Hatchback and as-per following the Honda factory service manual and Honda factory electrical manual for the wiring diagram for the Headlight Combination Switch.
Credit goes to Deshlong for finding a JDM Accord diagram that helped me understand how the unit worked.
These are examples of what they look like.

---------------------------------------------- Auto Light Sensor = ALS
Parking/Headlights = PHL
Combination Switch =CS
The following diagram will help you understand and modify your ALS harness.
If your PHL are off at the CS then you can push the big button on the side of the ALS IN, and when it becomes dark the sensor will take control of turning the PHL on automatically.
The ALS will only work if the ignition key is supplying power to the vehicle.
If you do not want the ALS to control the PHL then just push the big button on the side of the ALS OUT.
WARNING - I, nor Honda-Tech takes any responsibility for your actions. If you so do choose to try this then you do so at your own risk.
I suggest you solder the wires when splicing and use heat shrink. Please do not just twist the wires together and use electrical tape. You will more than likely short something leading to blown fuses, fires and headaches.
For those that do not understand the relay and how it works.
When Pin B and Pin D energize the coil in the relay from the Ignition Switch being turned, they close a switch inside the relay making Pin A and Pin C connect. That allows power from the WHITE wire to bypass the CS and supply it to the Headlights or Parking Lights (depending on which relay).
That is all this setup is. A light sensitive sensor that bypasses the CS.
I recently got the following equipment, it actually belongs to some Honda model other than EG or EK.
These connectors need to be removed as they are useless to incorporate this equipment in civic EG, for this I figured out the following line/wiring diagram.
and the actual wiring takes the following shape...
Installed and tested, the system works perfectly alright.
