I have a Battery Charger Lead (SAE). This makes it simple to attach a battery tender during bike storage. The charger lead is also fused (10amp) inline.
I discovered that I also have the [https://www.amazon.com/Honda-08A30-MCS-100-Accessory-Wire-Harness/dp/B00656YJ82/ Quartet Accessory Wire Harness] Honda 08A30 MCS 100 Although there's a link on Amazon, it is unavailable for purchase there.
Installation instructions can be found on the ST-Owners forum https://www.st-owners.com/forums/attachments/0007-st1300-quartet-harness-installation-20051207-01-01-pdf.5357/ with a photocopy of the original 4-page install instructions https://www.st-owners.com/forums/attachments/honda-quartet-harness-power-plug-installation-instructio-pdf.5965/ (both are linked from [https://www.st-owners.com/forums/threads/st1300-quartet-harness-installation.7714/ this forum post])

===New Stuff / Old Stuff===
Trying to figure out what wiring was already done (and removed!). There is one hole in the glove box - plugged with a rubber grommet. That one is about an inch or so. There are three holes cut into the locked compartment. The 1 1/4" bottom hole is sealed with duct tape. There are two more holes fore and aft at the top of the compartment.
Maybe I should get this $20 [https://www.easternbeaver.com/Main/Bike_Specific/ST1300/st1300.html#Quartet_Simplified_Harness_for_Honda_ST1300 "Quartet" simplified harness] from '''Eastern Beaver'''. It is made to simply connect to the existing wiring harness' "accessory" connector (located under the left side front cowl) and provides two outputs: a switched and an unswitched. Mating connectors and terminals are included so you can wire up whatever you want. See the [https://www.st-owners.com/forums/threads/st1300-quartet-harness-farkle-wiring-guide.26091/ ST1300 - Quartet Harness Farkle Wiring Guide] article on ST-Owners. '''This connector is already present, and unused - mated to the Quartet harness.''' I may be wired incorrectly? I need to re-check the voltage at the head end. If I ever decide to put power in the rear of the bike (e.g. top box, saddlebags), Eastern Beaver sells a wiring harness for that: ST1300 PC-8R Fuse Panel '''Electrical Connection''' used to sell connector parts, but as of this writing 2024, they only offer a cigarette lighter power plug for the ST-1300 https://electricalconnection.com/index.php/brand/honda/st1300/ This looks exactly like the broken / abandoned one I found inside the fairing on my bike.
