Going by your operation description it sounds like mine is operating as it should.
Low beams on, if i switch the Superlite toggle to on , nothing happens. It is only when i hit the high beam switch on the floor that the Superlite activates ( if the toggle is in the on position).
I wonder what changed between 69 & 70 to relocate the power wire? If I remove the fuse block it reveals no power source to the location of the connecting point to which your power wire is connected AND where the service manual says to it should be .
Again thank you... I will take photos a bit later to show the lack of power supply inside the bulkhead.
