3 PRONG HEADLIGHT CONFUSION

[ETEL64]

Hey yall, I have been stumped by a simple headlight prong issue. I have two schematics contradicting each other concerning the 3 prong headlight. Question is: If you look at the back of the HL with the prongs in a pyramid shape, which is the Hi, Low, Gnd?

From this pic it looks like the top is the low and the right side is the hi leaving left for the ground .
