Here is how I have done it. I have had at least one case where when loading the bike the loop got grabbed.

"I wrap the wire once around the bars so if they break I have extra to work with.
I also helps not bend the wires so much on the throttle side."
Note sure I would go to this trouble on the left:
"Underneath the LH grip I have epoxyed a throttle tube to the bars and now use a throttle side grip which is thinner. This way the heat is the same on both sides."
