Change "done correctly" to "splicing the black into the yellow/red, but leave the yellow/red connected to the JB" and I'll agree.
Every schematic I've seen indicates that the removal of the yellow/red wire from the JB removes the ground path for the primary coil of the headlight relay, requiring the blue-wire mod to be done to get your headlight back.
You may be right, and I'm not able to study the diagrams at the moment, or review this thread.
I already had the Blue Wire mod done when I did the Two-Wire.
My position has been to take as much away from the JB as possible, I would sell the bike before keeping the headlight relay.
Keeping the JB relays in operation is just asking for trouble later.
