Slowly but surely I am getting my VFR set up for waterproof USB power supplies. I got one installed tonite.
A company called http://3brpowersports.com/products.php has got just what I want but just like everything these days....they proud of their chit.
I removed all the fairings plus I removed the headlight composite from the upper fairing so I could have some access to measure for the clearance needed for the connector in the location I picked.
They call this the "Panel Tapp" Splash proof usb power port...
Using a 7/8" "boring bit" I drilled a hole and installed the port.
Here with the upper fairing installed without the headlight composite you can see it does clear.
From the battery I wrapped this spot with a triple layer of electrical tape for added protection against chafing.
Along the frame rail on the left side I zipped tied the wire to the linked brake lines.
..and then around the head stem.
I taped this connector to further help prevent any possible corrosion. I used red tape because I ran out of black.
They also have available "Tapp Capp" USB cable seal kit. You can use your own usb cable and put this waterproof seal on it. They also have some pre-fabbed sealed cables also but remember I said they're proud of their chit?
Not actually going to use this cable but here's a pic to give you an idea.
