Well, I did it.
First I needed to make a little box to hold the voltage regulator board that is currently located inside the male end of the 12v GPS cable.
So... I found a motorola wall charger for an old cell phone. It's the rectangle wall charger with the fold-up plugs. I pryed it open, pulled it all out, and cleaned up the insides.
I took the gps charger plug and opened it up and took out the voltage regulator board.
I unsoldered all of the existing leads from the voltage regulator board.
On the power "in" side of the board, I soldered on new 10" pigtails.
On the power "out" side I resoldered the shortened thin leads that go the the GPS interface plug.
I then wrapped the voltage regulator board and newly soldered wires with 3M electrical tape.
I placed the regulator board into the modified motorola wall charger "box" that I made.
I taped that up nice and double side taped it up under the fairing.
Hooked up my newly installed power outlet to a relay to power it only when the tailight is on (key on) using Eastern Beaver's adapter.
I cut the power cable much shorter.
I then cut my + and - wires on my power outlet receptacle that I wired in a week or so ago and soldered in my 10" pigtails and remade the connection that I had just cut (basically I spliced my pigtails into the outlet receptacle wires.
Now my GPS cord is hardwired, I don't need to plug it in and have it fall out, I don't need to use either my GPS or my cell phone charger, and it's powered off when I turn the key off (thanks to the relay).
I works great.
All connections were soldered and shrink tube wrapped.
