What a strange and somewhat informative thread.
Well that is an interesting observation. Admittedly I was learning as I went and yes it was quite confusing tracking down the part numbers and actual characteristics offered for purchase. And in fact Glider's diagram is obviously for Touring models and it does not show a hot all the time lead so that agrees with my Dyna schematics except for wire colors.
Here is my summation of which I have gathered from many different sources.
1.The (on bike) Dyna Cust Accy plug #72104-94BK has the following wires, black is ground, the two o/r wires are switched to ignition, r/y 'adds' rear lighting items.
The additional purchase #70264-94A add on pigtail unit comes with two pigtails and plugs into the above #72104-94BK.

2. The (also on bike) Dyna P&A Battery (aka B+ connector) #72260-04 is fed from the TSSM battery terminal and is hot all the time and has one single red positive wire.
The additional purchase #70270-04 add on pigtail unit comes with 3 pigtails and can be also used for additional accessory items, but ground must be created and inline switches installed if hot all the time not desired. This plugs into the #72260-04 shown above..
------------
3. In addition, part number 91843-97 is a cigarette lighter type power outlet with a waterproof end cap. Can be used with gps etc. Approximately 12inches of cable included, and plugs into the above #72104-94BK (or pigtail #70264-94A thereof).

If you don't like splicing into OEM harness wires (which I don't) then you will need this information one day. I just got through cleaning up a mess of spliced in wiring done on my bike before I owned it. I replaced one section of the harness totally. ANY time I can I will use the above plugged scenarios to link ANY and all accessories (up to the maximum fused amperage) avoiding cutting and splicing into the OEM harness.
