So the only bezels I have from my dissembly were
Choke
Ignition
Flashers
Lights
Cigarette lighter
Defroster
Fan/heat
Temp control.
Which know only makes me more confused. On top of the mystery hole looks like things where not in their proper hole homes. And the brake warning light was missing entirely. I think the Mister hole was the lighter, and where the lighter should have been looks like there was a switch installed without a bezel. So now what was the mystery switch for?
Anyways is there a traditional bezel look for a USB port?
You are only confused because you are trying to make sense of what the "last guy" did.
If you stop trying to figure out what the extra hole is for...then everything will become much more clear.
The "Extra hole" was used as a cigarette lighter. It was added after hole #7 was repurposed with a small toggle switch and a big washer. So after hole #7 was occupied, someone later added a hole.
The extra hole is not the mystery switch. The mystery switch is the one that was in hole #7, and it was a small (maybe 1/2 diameter) hole.
If you move the radio power wire to the cigarettel lighter, then the cigar lighter hole makes an excellent USB resource, or the giant DIN hole that someone cut out will likely have something with USB capability.
