Noob question; Installing intellitronix digital gauge, (tw: LOTS OF DUMB QUESTIONS)

Team,

I got the attached diagram off of mymopar (named "Dodge 6.jpg" its for a 74 Dart) and just got an epiphany, between the two attached image I think one is inverted. If you're looking straight at the printed circuit connector vs behind.

To add a layer of complexity, my printed circuit connector is letters. But I think A is 1, B is 2, 3 is C, and so on...

I am wondering if you will agree with my course of action;

IGNORE the wire colors and just use the position of wires based on the diagrams.

I am wondering about your thoughts on this.
