Went back to old Holden where I found the diagram for agro.
I found this diagram aswell
http://gallery.oldholden.com/d/37241...nt_Page_65.jpg
Notice down the bottom of the pages it has the option codes ,BUT that is not the interesting thing I found
Page 65 is for a twin h/light front wired at the factory and the other (page58) is for a dealer upgrade to twin h/lights..
Also notice that the factory has inboard lights as low beam ,outboard as high beam..
The up graded has low\high as inboard and auxiliary hi beam on the outside..
Playwme I'm sorry to say that the two pin plug has nothing to do with being a factory twin headlight front as my van has a single h/light front and not has been changed/damaged at anytime..
