I noticed that 3rd blank receptacle on the H-D harness...it is unused, as I use my 2 position plug on my Deltran battery tender in the correct mating connections without issue. :small3d002:
OK, there's some progress, but, does anyone know what it's for? Please... don't tell me I've got all of you stumped! :small3d031: Don't make me break out my shop manual, this is much more fun! Besides, if I have to resort to the manual, then I'd have to find my reading glasses.
