New Moto Guzzi Door Mats Available Now
Pop an aluminium plate over the gap to hide the wiring. Doesn't need to be thick and you already have mounting points (captive nuts). Wouldn't take much effort to form it around the underside too. Then it should look tidy, rather than missing.
.. I'd just have to reverse those two captive nuts on the bottom to mount it ..
"If I'm seeing the image correctly, then all captive nuts are correct, as is..."
I think the captive nuts that the yellow arrows are pointing at need to be reversed, so they look like the ones the red arrows are pointing at. That will give me four mounting points for whatever cover I come up with, secured with button head bolts from the wheel side, not the plate side.
Nah, your plate would then need to be an elongated Z shape, rather than a capital J | /|__/
