Headlight wiring on s13 hatch (not silvia issue)

[GripTerror]

I am making dual projector headlights on my hatch.

I am using a lo beam projector and hi beam projector 9005 bulbs. I have an hid ballast kit for the lo beam but will retain halogen hi beam.

The original headlight lamp has a three prong (sp? name?) socket.

The lo beam and hi beam have a two prong (lol name of that thing) socket... as does the hid kit connector...

I want to retain the lo/high beam stanard knob in car. So when I turn light on lo beams come. When I switch knob high beams come on, and if i flick the switch hi beams flash. I want to basically retain that stock functionality.

I am not sure what the three sprokects/prong whatever on the socket are... I am ASSUMING one is for the lo beam, one is for the high beam and one is ground???

I would have to chop stuff I am assuming... give me a helping hand.
