In the rear, the light green/gray wire going to the passenger heated grip lighting is a good choice. Not sure of the best choice in front. Ideally, you would want to get something that goes through the load-shedding relay like the rear grip lighting. The gauge lighting wires would be a good choice, but they are ignition switched, not active only after the engine starts. Be aware that the RT already has a 10 amp connector that is hot all the time, up front. This is meant for a second power outlet, like in the rrunk, but is tied to the left suspension tower as a spare.
