I have been on the hunt for a 6-pin Honda DLC connector to power cable. Unfortunately the only product I have been able to find was thanks to @dmonkey but only works for the 4 pin JA55.
Here is that product for the JA55:

I have come across a connector with pins however, where you could create your own cable. My plan is to use the power and ground off that DLC connector to create a power source for one of either led podlights, GPS, or USB charger. All you would have to do is figure out which 2 wires to connect to, then create the adapter like the above finished one available on we-bike. Green is ground, Black/white is power.
Hope this helps someone out, here is the link on eBay:

Here's what I've come up with.
OptiMate CABLE O-77 (I purchased through RevZilla) is a 6-pin Euro5 OBD2 connector on one end (only 2 pins are present and wired), 2P SAE plug on the other.
"40cm (16”) length, 7.5A fuse, rated for 3A (5A max) current, ziptie securing slots on SAE connector."
They were nice enough to provide a pin-out diagram showing you exactly which pins are present as - and +
Though this is intended to be used to charge the battery, it works the other way around all the same and you can power an accessory from it.

I plugged it into the DLC port on my Dax 125, connected a Dynaplug tire inflator which has an SAE power connector to it, and it worked as expected with ignition switched power. The inflator was powered when the key was on, not powered when the key was off.

I did have some trouble releasing the plug, both from the blank panel that holds it on the bike, and from this Optimate connector. Simply pressing down on the release tab didn't lift the opposite end enough to clear the retention bump. The solution I found was to insert a small flat blade screwdriver in the opposite end from the push tab, to lift the cantilever enough to clear the retention bump.

From what I can find, it seems the current rating for the 6P connector may be around a max of 3.5A. So keep that in mind with whatever accessories you continuously power with it. You may need to use this power to trigger a relay with the accessory powered from the battery.

So my test of using the Dynaplug, I wouldn't recommend doing as it can pull ~4.5A

On the older 4P connector I power a Garmin XT2 on my CT125, and that has a max draw of 1.5A. That's held up fine under continuous long term use.
