I don't think that will work if I'm reading the wiring diagram correctly. It appears that all you've done is bypass the fuse and both wires would be hooked up to 12v+. In addition, even if you hooked one wire up to a typical ground wire, then it (transponder) would be on all the time because the wires that you tapped into feed the Headlight high beam relay not the headlight bulb. I suggest that you tap into the White with Red stripe wire coming out of the Hi Beam headlight relay for the 12v+ connection, and any Black with yellow stripe wire you can find for the ground connection. The head light high beam relay is located under the top cover sitting on top of the gas tank (three screws holding it down). (there are four relays there, make sure you have the correct one) or you can just go straight to the wires coming out of the headlight as the instruction online video shows, but I hate working down there in the dark where your own arm and hand constantly block your light and your view.
I'd tap in at the relay up top. Good Luck!
Might want to wait for someone else to chime in, as I'm not always as smart as I think I am.
